All the living organisms respond and react to
changes in the environment around them.
The changes in the environment to which the
organisms respond and react are called
stimuli such as light, heat, cold, sound, smell,
touch etc.
Both plants and animals respond to stimuli but
in a different manner.

Control and Coordination in animals is done with
the help of two main systems:
(i) Nervous system
(ii) Endocrine system

Nervous System
Control and coordination in organisms
are provided by nervous and muscular
tissues.
Nervous Tissue: This tissue is composed
of an organized network of nerve cells or
neurons specialized for conducting
information via electrical impulses from
one part of the body to another.

Receptors are specialized tips of some nerve cells that detect information from the
environment.
Receptors are located in various sense organs:
Ear: Acts as phonoreceptors, responsible for receiving sound and helping in
hearing and maintaining body balance.
Eyes: Acts as photoreceptors, receiving light and facilitating vision.
Skin: Acts as thermoreceptors, sensing temperature changes and facilitating the
perception of heat, cold, and touch.
Nose: Acts as olfactory receptors, responsible for the sense of smell.
Tongue: Acts as gustatory receptors, facilitating the sense of taste.
