What type of nerves are spinal nerves Are they Afferent Efferent or Mixed?
mixed
What type of nerve sends messages from sense organs to the brain?
This is simple; don't overthink it. The nerves that carry sensory impulses to the brain are the sensory nerves.
How fast do nerves impulses travel?
Nerve impulses travel through nerve fibers via a action potential and the speed at which the impulse travels depends on the type of nerve fibre. This can range from 100m/s in the case of touch to 20-30 m/s when you're thinking.
Are nerves and nerons the same thing?
You may mean 'are nerves and neurons the same?' They are not the same Nerve : Any of the cordlike bundles of fibers made up of neurons through which sensory stimuli and motor impulses pass between the brain or other parts of the central nervous system and the eyes, glands, muscles, and other parts of the body. Nerves form a network of pathways for conducting information throughout the body. Neuron: Any of the impulse-conducting cells that constitute the brain, spinal column, and nerves, consisting of a nucleated cell body with one or more dendrites and a single axon. Also called nerve cell. (American heritage Dictionary)
What is the type of cell also known as a neurone?
There are many neurons in the human brain (~ 100 billion) but glial cells outnumber neurons by 10 fold. Therefore, the most abundant cell type in our brain would be glial cells of which astrocytes (a type of glial cell) is the most numerous. http://en.wikipedia.org/wiki/Neuron
What type of nerves are spinal nerves Are they Afferent Efferent or Mixed?
mixed
What is the nerve cells type of cells job?
it nerves around
What type of nerve sends messages from sense organs to the brain?
This is simple; don't overthink it. The nerves that carry sensory impulses to the brain are the sensory nerves.
What part of the body does nerve entrapment affect?
refer to a particular type of pinched nerve, in which peripheral nerves are chronically compressed resulting in pain or loss of function in an extremity. The most common nerve entrapment syndromes affect the median, ulnar and radial nerves of the arms.
What type of nerve cells receives stimuli for the sense of small?
Olfactory nerves, definetly. We're studying this currently in my grade.
What is neuralgia?
Neuralgia is a sharp pain that affects nerves, whether it be individual nerves or a group of nerves. Neuralgia is a special type of pain in that it occurs without the stimulation of a pain receptor. How does the pain occur? When the nerve or nerves it's affecting are irritated or damaged.
What is the type of canal that runs through bone and contains blood vessels and nerves?
a nutrient foramen
Can the nervous system repair its cables?
The nervous system is comprised of nerves called neurons, not 'cables'. Different nerve cells can reproduce to create newer nerve cells to replace damaged cells.
What type of nerve stimulates muscle cells to contract?
Somatic type of nerves stimulate the muscle cells to contract.
What nerve is particularly vulnerable to injury in a shoulder dislocation human anatomy?
All nerves forming the brachial plexus are vulerable to injuries. Most commonly affected are axillary nerve, suprascapular nerve and the radial nerve. The axillary nerve is injured in 37% making it the most commonly injured structure with this type of injury.Suprascapular nerve at 29%, and the radial nerve (22%).
What is the peripheral nervous system?
It includes nerves arising from brain and spinal cord innervating different parts of the body respectively called as, cranial and spinal nerves. Comprises of all nerves which connect the central nervous system with receptors and effectors. Nerves connecting the receptor organs to the CNS are called sensoryor afferent nerves; they contain sensory fibres only. Nerves connecting the effector organs (muscles and glands) to CNS are motor or efferent nerves; they contain motor fibres only.A third type of nerve, the mixed nerves have both sensory and motor nerve fibres. Nerves connected to brain are called cranial nerves while those connected to spinal cord are spinal nerves. On the basis of presence and absence of myelin sheath around the axons the nerve fibres are myelinated or nonmylinated, respectively.• Each nerve is composed of many nerve fibers enclosed within a connective tissue sheath. A nerv fiber is along axon or dendrite of a neuron, which could be either sensory or motor or both. The periphery of something is its edge, or outside parts.Thus that part of the nervous system which is not designated the Central Nervous System (the brain, spinal chord and retina) would be regarded as the peripheral nervous system. It consists of sensory neurons, clusters of neurons called ganglia, and nerves connecting them to each other and to the central nervous system.
What type of mixture contains two or more substances that are evenly mixed?
homogeneous mixture
