Why nervous system can reach only the cells connected by nervous tissue - isn't the whole of our body connected with nervous tissue if not which parts are not connected?
Why - because we're not magical. If there isn't a nerve then there isn't any sensation (or motion/control).
Biggest example of no connection is the brain itself ... it can NOT feel itself.
Another cute example is calluses - they insulate the nervous system from the outside world.
For even weirder results ... check out the blind spot (which you can't see, and you can't tell that you can't see).
What else can I help you with?
What type of tissue Contains schwann cells?
Schwann cells are glia that myelinate the neurons of the Peripheral Nervous System
What tissue are in the nervous system?
the brain,spinal cord and the nerves
Axons and dendrites usually are found in cells of which tissue?
Axons and dendrites are found in nerve cells, which are part of the nervous tissue. Nerve cells, or neurons, are responsible for transmitting electrical and chemical signals throughout the body to facilitate communication between different parts of the nervous system.
What represents a correct sequence of levels within the hierarchy of life?
These are the choices, it wouldn't let me put it in the main question. a. brain, spinal cord, organ system, nerve cell nervous tissue b. organ system, population of cells, nervous tissue, brain c. organism, organ system, tissue cell, organ d. nervous system, brain, nervous tissue, nerve cell e. organ system, tissue, molecule, cell
What system receives and proccesses info and controls how the body reacts and moves?
The nervous system receives and processes information from the body's senses, then coordinates the body's responses by sending signals to muscles and glands. This system controls bodily functions and movements by integrating sensory input with motor output through a complex network of neurons.
What germ layer does the tissue of the peripheral nervous system develop from?
All nervous tissue arise from ectoderm. Whether central or peripheral. It is anatomical division. Functionally all nervous cells are connected to each other.
Nervous tissue consists mainly of neurons and collagen fibers?
Actually, nervous tissue is composed of neurons, which are responsible for transmitting electrical signals, as well as glial cells that support and protect neurons. Collagen fibers are mainly found in connective tissue, not nervous tissue.
Is the nervous system a network of cells and tissue?
Yes, for the most part.

Schwann cells are glia that myelinate the neurons of the Peripheral Nervous System

What are nueron in nervous tissue?
neurons are just the cells that make up the nervous tissue.
What is made of nervous tissues?
nerve cells make nervous tissue and muscle tissue is made up of muscle cells
The majority of nervous tissue is composed of supporting cells called?
Non-conducting support cells of the nervous system or 'Neuroglial' cells represent a range of cells which function to maintain the nervous system. Some common ones are: Astrocytes envolved in providing nutrients and creating the blood-brain barrier Microglia are the immune cells of the nervous system Oligodendricytes and Schwann Cells produce the myelin sheaths which insulate the axons of neurons Ependymal cells secrete cerebrospinal fluid That's just a few
What is the differences between the nervous tissue and nervous system?
Nervous tissue is made up of different cells working together to perform a given function -- in this case, to carry messages from one part of the body to another. Different nervous tissues working together make up nervous system organs, such as nerves, the spinal cord, or the brain. These organs work together in the nervous system, a collection of organs performing a body function. So, in sum, the difference between nervous tissue and the nervous system is one of size and scope: nervous tissue makes up nervous organs, which make up the nervous system.
