Question

About neural tissue and its types parts functions?

Answer 1

Nervous tissue or nerve tissue is the main tissue component of the two parts of the nervous system; the brain and spinal cord of the central nervous system (CNS), and the branching peripheral nerves of the peripheral nervous system (PNS), which regulates and controls bodily functions and activity. It is composed of neurons, or nerve cells, which receive and transmit impulses, and neuroglia, also known as glial cells or more commonly as just glia (from the Greek, meaning glue), which assist the propagation of the nerve impulse as well as providing nutrients to the neuron.

Nervous tissue is made up of different types of nerve cells, all of which have an axon, the long stem-like part of the cell that sends action potential signals to the next cell. Bundles of axons make up the nerves.

Functions of the nervous system are sensory input, integration, control of muscles and glands, homeostasis, and mental activity.

Answer 2

Hello 
______________________________________________________________
About 98% of neural tissue is concentrated in the brain and spinal cord, which are the control centers for the nervous system.
______________________________________________________________
@ The nervous system includes all the neural tissue in the body.

@  Neural tissue contains 2 kinds of cells:
1. neurons: the cells that send and receive signals
2. neuroglia (glial cells): the cells that support and protect the neurons

@  The organs of the nervous system include:
- the brain
- the spinal cord
- sensory receptors of sense organs (eye, ears, etc.)
- the nerves that connect the nervous system with other systems.

@  The nervous system has 2 major anatomical divisions:
1. the central nervous system (CNS)
2. the peripheral nervous system (PNS)
