Question

Explain the following terms: (i) synapse (ii) stimulus and (iii) impulse

Answer 1

Answer:

here is answer

Explanation:

1.Synapse

In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target efferent cell

2.All the living organisms (plants and animals) respond ans react to changes in the environment around them. the changesin the environment to which the organisms respond and react are called stimuli ( singular- stimulus)

3.Nerve impulse-

A nerve impulse is a wave of electrical activity that passes from one end of a neuron to the other.

A nerve impulse is an electrical signal that travels along an axon.

Answer 2

The explaination of the terms - sypnase, stimulus and impulse is given below :

(i) Sypnase

Between two cells of nerve, there is presence of a junction which has a small gap through which the signal passes. This junction is known as or termed as sypnase.

(ii) Stimulus

It is the response of any living ones towards any action.

(iii) Impulse

It is the other name of the signal which travels through the nerve's length. It is the information which passes via the nerve fibre.
