Nervous Tissue

Question 1 What are the function of nervous tissue?

Question 2 Define the term neuron?

Question 3 Explain the structure of nerve cell?

They are highly specialised for being stimulated and then transmitting the stimulus very rapidly from one place to another.

Brain, spinal cord, nerves are made up of nervous tissue.

Nervous tissue contain unit cell called nerve cell or neurons.

The impulses travel one one neuron to another neuron.

 

(1) It consist of cell body which contain central nucleus and cytoplasm from which long thin hair like part arises called dendrons.

(2) The axon is a single, long, cylindrical structure that conduct electrical impulses  away from neuron’s cell body.

(3) The dendrons further branches into dendrites.
