What is nervous system tissue?

How many types of nervous tissue are there?

Nervous tissue is composed of neurons and supporting cells called neuroglia, or ” glial cells.” There are six types of neuroglia. Four are found in the central nervous system, while two are found in the peripheral nervous system.

What is nervous tissue and its types?

Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. … These cells have three principal parts: the dendrites, the cell body, and one axon.

Why is nervous tissue unique?

Our nervous tissue allows us to experience stimuli and then make a response. … Neurons are highly specialized nerve cells that generate and conduct nerve impulses. Dendrites are responsible for responding to stimuli; they receive incoming signals towards the cell body.
