explain the structure of nerves tissue
Answers
Answer:
ANSWER :
Nervous Tissue
→ They are highly specialized tissue due to which the animals are able to perceive and respond to the stimuli.
→ Their functional unit is called as nerve cell or neuron.
→ Cell body is called cyton which is covered by plasma membrane.
Dendron
→ Short hair like extensions rising from cyton are Dendron which are further subdivided into dendrites.
Axon
→ Axon is long, tail like cylindrical process with fine branches at the end.
→ Axon is covered by a sheath.
→ Axon of one neuron is very closely placed to the dendrons of another neuron to carry impulses from one to another neuron in the form of electrochemical waves.
→ This close proximity is called as synapse.
Explanation:
Nervous tissue is made up of different types of nerve cells, all of which have an axon. An axon is the long stem-like part of the cell that sends action potential signals to the next cell. ... Functions of the nervous system are sensory input integration, control of muscles and glands, homeostasis, and mental activity.
