Question

nervous and hormonal systems together perform the function of Control and coordination of human beings justify the statement

Answer 1

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 receive the stimulus from surrounding environment and send the message received 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 effectors 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, only 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.

Answer 2

this system of control and coordination can be divided into work parts
(1) nervous system
(2) hormonal system
both the systems are control and coordination the various function in human body.
nervous system control the various function by the units called neurons.
neurons receive the information by the sensory nerves system and transfer them through motor actions
the hormones system are the chemical secreted by endocrine glands. the endocrine glands do not have ducts so they are called ductile glands
hormones also control the function of various organs of the body.
that the nervous system and hormones system in human body together perform the function of control and coordination.
