Answer 1

Answer:

$\huge{Your\:Answer:-}$

Ans 1 :- Receptors are groups of specialised cells. They detect a change in the environment (stimulus) and stimulate electrical impulses in response. Sense organs contain groups of receptors that respond to specific stimuli.

2 Ans :- There are three general categories of cell-surface receptors: ion channel-linked receptors

G-protein-linkedreceptors, and enzyme-linkedreceptors.

3 Ans :-1)sensory neurons—receive impulses and carry them from the sense organs to the spinal cord or brain.

2) interneurons—connect sensory and motor neurons and interpret the impulse; only in the brain and spinal cord. An impulse travels along the neuron pathways as electrical charges move across each neural cell membrane.
