Answer . This tissue is very different because this is the only tissue that carries brain signals from the brain to the body.
neurons (brain cells) & neuroglia (support) --------------------------------------------------- . Multipolar Neurons (3+ processes) They are the most common neuron type in humans (more than 99% of neurons belong to this class) and the major neuron type in the CNS Bipolar Neurons Bipolar neu…rons are spindle-shaped, with a dendrite at one end and an axon at the other . An example can be found in the light-sensitive retina of the eye. Unipolar Neurons Sensory neurons have only a single process or fibre which divides close to the cell body into two main branches (axon and dendrite). Because of their structure they are often referred to as unipolar neurons. . (MORE)

Skin is supplied with nervous tissue. That is why you feel the various types of sensations from the skin.
Nervous tissue is the main component of the two parts of thenervous system which are the brain and spinal cord of the centralnervous system. It is also the main component of the branchingperipheral nerves of the peripheral nervous system, which regulatesand controls bodily functions and activity.
Nervous tissue sense stimuli and transmits signals from one part of an animal to another. The functional unit of the nervous tissue is the neuron, or nerve cell, which has a unique structure that is specialized to transmit signals called nerve impulses. A nerve cell consists a body and two or more e…xtensions called dendrites and axons, which may be as long as a meter in humans. They perform the major function of transmitting nerves impulses. Anatomically, a nerve tissue comprises of many neurons that are joined by the connective tissues. Functions Are: 1. Sensory input 2. Integration 3. Controls of muscles and glands 4. Homeostasis 5. Mental Activity (MORE)
The functional unit of nervous tissue is known as the neuron. Thisis made up of the cell body, axon and dendrite.
nervous tissue are the nerves going to the heart that control an individuals heart rate. It also sends messages to the important functions of your body.
Nervous tissue is the only tissue in your body that cannot replace or regenerate itself.
Nerve tissue consists of nerve cells, nerve fibers, dendrites, andneuroglia. It is packed closely together and most are stronglybranching. Its function are to regulate and control body processes.
2 types of nervous tissue\n. \nNeurons- generate and conduct nerve impulses\n. \nNeuroglia- non conducting, support and protect the neurons, their presence does speed up conduction
The spinal cord and all nerves are composed of nervous tissue. The myelin sheath conducts nerve impulses.
The organ it is found in is the brain, but another main part of the body it can also be found in is the spinal cord.
Sympathetic innervation of the heart is from cardiac accelerator nerves descending from the uppermost thoracic sympathetic ganglia and the cervical sympathetic ganglia. Parasympathetic innervation comes from the vagus nerve (Cranial Nerve X). These nerves continue into the walls of the heart and pro…vide autonomic innervation, which can only modify the rate and contractility of the heart. Inside the heart, intrinsic pacemaking comes from the sinoatrial node, which automatically paces the heart due to the existence of "funny currents" (seriously, that's what they're called) that depolarize the node. The SA node is located in the right atrium and the depolarization follows tracks to the left atrium and the atrioventricular node. The AV node can automatically depolarize, but it does so at a lower rate than the SA node, so the SA node overrides the AV nodal rhythm. From the AV node, the electrical signal goes through Bundles of His and Purkinje Fibers to deliver a wave of depolarization to the cardiac muscle. These cells are modified cardiac myocytes between the endocardium and the myocardium specialized for the transmission of electrical impulse. Technically, these are not nerves, though they function similar to nerves. Beyond that, there are gap junctions between cardiac myocytes in the intercalated disks that allow for the coordinated contraction of cardiac muscle. In other words, the cells are arranged like a net and the depolarization and contraction of one cell leads to the depolarization and contraction of the cells next to it that have not yet been depolarized.

the job of the nervous tissue is that it is to react to stimuli andis to conduct impulses to various organs in the human body.
The nervous system and the entire coordinating center of the body, such as, brain and the spinal cord.
The peripheral nervous system is composed of sensory neurons and the neurons that connect them to the nerve cord, spinal cord and brain, which make up the central nervous system
Nervous tissue's main purpose is to react to stimuli and sendimpulses to various organs in the body which then return and relaya direct response to stimulus. Nervous tissues are made up ofmillions of nerve cells which are known as neurons.
That is correct. In case of the embryo, you have three layers, in initial period. The cells from the ectoderm enter the mesoderm to form the neural tube. So the neural tube is formed by invagination of the ectoderm in the mesoderm. Your nervous system is developed from this neural tube. In vertebr…ates, ectoderm gives rise to hair, skin, nails or hooves, the lens of the eye, the epithelia (surface, or lining, tissues) of sense organs, the nasal cavity, the sinuses, the mouth (including tooth enamel), the anal canal and nervous tissue , including the pituitary body.

General All living cells have the ability to react to stimuli. Nervous tissue is specialised to react to stimuli and to conduct impulses to various organs in the body which bring about a response to the stimulus . Nerve tissue (as in the brain, spinal cord and peripheral nerves that bra…nch throughout the body) are all made up of specialised nerve cells called neurons . Neurons are easily stimulated and transmit impulses very rapidly . A nerve is made up of many nerve cell fibres (neurons) bound together by connective tissue. A sheath of dense connective tissue, the epineurium surrounds the nerve. This sheath penetrates the nerve to form the perineurium which surrounds bundles of nerve fibres. blood vessels of various sizes can be seen in the epineurium. The endoneurium , which consists of a thin layer of loose connective tissue, surrounds the individual nerve fibres. Although the system forms a unit it can be divided into the following parts: the central nervous system (CNS) which consists of the brain and spinal cord, the nervous system consists of the nerves outside the CNS which connect the brain and spinal cord to the organs and muscles of the body and the automatic or involuntary nervous system consists of nerve centres and fibres inside as well as outside the central nervous system. There are three main types of neurons , which are classified according their function: Those that conduct impulses from the sensory organs to the central nervous system (brain and spinal cord) are called sensory (or afferent) neurons ; those that conduct impulses from the central nervous system to the effector organs (such as muscles and glands) are called motor (or efferent) neurons . Interneurons (also known as connector neurons or association neurons) are those that connect sensory neurons to motor neurons. Structure of a Motor Neuron A motor neuron has many processes ( cytoplasmic extensions ), called dendtrites , which enter a large, grey cell body at one end. A single process, the axon , leaves at the other end, extending towards the dendrites of the next neuron or to form a motor endplate in a muscle. Dendrites are usually short and divided while the axons are very long and does not branched freely . The impulses are transmitted through the motor neuron in one direction, i.e. into the cell body by the dendrites and away from the cell body by the axon . The cell body is enclosed by a cell (plasma) membrane and has a central nucleus . Granules, called Nissl, bodies are found in the cytoplasm of the cell body. Within the cell body, extremely fine neurofibrils extend from the dendrites into the axon. The axon is surrounded by the myelin sheath , which forms a whitish, non-cellular, fatty layer around the axon. Outside the myelin sheath is a cellular layer called the neurilemma or sheath of Schwann cells . The myelin sheath together with the neurilemma is also known as the medullary sheath . This medullary sheath is interrupted at intervals by the nodes of Ranvier . . A motor neuron . Nerve cells are functionally connected to each other at a junction known as a synapse , where the terminal branches of an axon and the dendrites of another neuron lie in close proximity to each other but never make direct contact. . A Synapse . Classification of Neurons On the basis of their structure, neurons can also be classified into three main types: . Unipolar Neurons. Sensory neurons have only a single process or fibre which divides close to the cell body into two main branches (axon and dendrite) . Because of their structure they are often referred to as unipolar neurons . . Multipolar Neurons. Motor neurons , which have numerous cell processes (an axon and many dendrites) are often referred to as multipolar neurons . Interneurons are also multipolar. . Bipolar Neurons. Bipolar neurons are spindle-shaped, with a dendrite at one end and an axon at the other . An example can be found in the light-sensitive retina of the eye. . A diagram showing the different neurons . Functions of Nerve Tissue . Nervous tissue allows an organism to sense stimuli in both the internal and external environment . . The stimuli are analysed and integrated to provide appropriate, co-ordinated responses in various organs . . The afferent or sensory neurons conduct nerve impulses from the sense organs and receptors to the central nervous system . . Internuncial or connector neurons supply the connection between the afferent and efferent neurons as well as different parts of the central nervous system. . Efferent or somatic motor neurons transmit the impulse from the central nervous system to a muscle (the effector organ) which then react to the initial stimulus . . Autonomic motor or efferent neurons transmit impulses to the involuntary muscles and glands . (MORE)
Yes, fatty tissue is in the nervous system. Without fatty tissue being in the nervous system, you may be a target for serious medical problems that could be fatal.
The heart is an organ made up of tissue. Body tissue is another name for the cells you are made of.
Nervous tissue consists mainly of nerve cells and glial cells.Glial cells are the most abundant cell types in the central nervoussystem.
Brain, spinal chord, skin, eyes, nose, inner ear...pretty much anywhere you can feel, sense, or move.
Yes. The brain is composed of two kinds of nerve cells neurons (which are either afferent, interneurons, or efferent) and neuroglia (which has several subtypes).
No, it is an organ, because it is made out of lot of tissues like muscle tissue, connective tissue, etc.
Yes. For example, some nervous tissue ennervates the smooth musclethat constricts the respiratory passages, or causes you to cough ifsomething "goes down the wrong tube."
Neural impulses cause diaphragm and chest cage to move down wards and outwards respectively so that air can move into lungs Cough reflex is mediated by nerve impulses/reflexes
To relay sensory information to the brain for interpretation and motor information to the muscles for voluntary or involuntary control. Nervous tissue also fulfills many other roles, like innervating organs that may release hormones.
The two are related in that nervous tissues helps detect stimuli,and muscle tissue helps avoid or embrace it. This is important toanimals to be able to avoid dangerous stimuli.
It controls the function of the muscles of the wall of the stomach and the muscular sphincter. Also, the nervous tissue controls the secretory function of the stomach.
There are several characteristics of nervous tissue that make themeasy to identify. Nervous tissue is made of many cells packedclosely together, and most are strongly branching. There are twomain groups of cells: the neurons, and the glial cells. You willfind nervous tissue in the brain and spinal c…ord, and in the nervesand their associated ganglia.

Unmyelinated tissue is substantially slower in conducting impulses along the axon. With myelinated axons, the action potential (impulse) jumps from node to node greatly increasing the speed of the impulse.
Nervous tissue is composed of nerves containing neurons, specialized cells. Muscle tissue contains myocytes, which have completely different structure than neurons. Also, muscle is organized in many fibers covered by connective tissue; these fibers build up stronger fibers etc. Neural tissue has dif…ferent organization. (MORE)
Nervous tissue is made up of different cells working together toperform a given function -- in this case, to carry messages fromone part of the body to another.

Cardiac muscle is found in the heart. The other two types of muscle are smooth and striated (skeletal) muscle. Cardiac muscle, the third kind of muscle (the other two being skeletal and smooth muscle.
The differences between these two tissue types is nervous tissues use electrical impulses to carry out their function while on the other hand muscle tissues rely on contracting of muscles to carry out their functions. Also nerve tissues are formed up from nerve cells called neurons whereas muscles t…issues are formed from different types of cells related to their function. Nervous tissues function is to send signals around the body and to communicate within cells whereas muscle tissues function is mainly on movement and protection. Samad golzadeh (MORE)
Heart has cardiac tissue. It is striated like skeletal muscle, but is under control of the autonomic nervous system.
they all make up parts of our body. i just figured that out myself. insert hand hitting head here.
No, the nervous system is derived from the ectoderm. The mesoderm mainly makes muscles, red blood cells, and some kidney cells.
The nerve tissue vaccines are no longer available due to poor efficacy and life threatening adverse effect of neuroparalytic reactions. The currently available vaccines are the modern tissue culture vaccines (MTCV) and include Purified Chick Embryo Cell (PCEC) vaccine, Human Diploid Cell Vaccine (HD…CV), Purified Vero Cell Vaccine (PVRV), Purified Duck Embryo Vaccine (PDEV). The vaccines are available in lyophilized form with sterile water as diluent, are stable for 3 years at 2 to 8Â°C and should be used within 6 hours of reconstitution. All tissue culture vaccines have almost equal efficacy and any one of these can be used. These vaccines induce protective antibodies in more than 99% of vaccinees following pre/ post exposure prophylaxis. The main adverse effects are local pain, swelling and redness and less commonly fever, headache, dizziness and gastrointestinal side effects. Systemic hypersensitivity reactions in vaccinees have been reported with HDCV particularly following booster injections but not with PCEC/ PVRV. Intradermal vaccination may cause more local irritation as compared to the intramuscular route. Along with proper wound care and rabies immunoglobulin (RIG) post exposure prophylaxis is effective in preventing 100% of rabies cases. Failures occur due to delay in initiation or non use of RIG when indicated. (MORE)
yes. cniddarians have both muscle and nerve tissues.There are nervebranch thoughout the body. It can control the contractile of themuscle like tissur for feeding and locomotion.
Nevous tissue forms in the brain, spinal cord and nerves. Mostly in the brain, though.
A nervous system, which can be used with other tissues like epithelial and muscle tissue, and they make up a stomach. Hope this helps
Livestock is pretty much enervated the same way as a human. Brain, spinal column, major, and minor nerve branches all the way to the pain receptors in the skin, autonomic and voluntary nervous systems. (Would be nice if I didn't get logged out in mid answer.)
