Answer:
The working together of
various organs of human being in a systematic, controlled and efficient way to
produce a proper response to various stimuli is known as coordination. In humans,
the nervous and hormonal system together perform this control and coordination.
Nervous System
consists of receptors that receives the stimulus from surrounding
environment and send the message conveyed by them to the spinal cord and
brain in form of electrical impulses through the sensory nerves. The
motor nerves then transmit the response to the 'effector'. The
effector are mainly the muscles and glands of our body,
Thus,
endocrine glands secreting hormones are directly or indirectly
controlled by the nervous system.
Hence,
control and coordination in humans (or animals) depends on two things for transmitting
information i.e., chemical signals of hormones and nerve impulses.
If they
depended only on nerve impulses through nerve cells, a limited range of tissues
would be stimulated. Since, they get additional chemical signals as well, a
large number of tissues are stimulated. This is why animals can show a wide -
range of response to stimulus.
