Nervous and hormonal systems together perform the function of control and coordination in human beings.” Justify the statement.

Nervous and hormonal systems together perform the function of control and coordination in human beings. The nervous system consists of nerves or neurons which controls and coordinates all the functions in the body. Nervous system consists of sensory receptors which collect information from the external environment in the form of stimuli and then sent them to the brain in the form of electric impulse. In the brain, Information is interpreted and instructions are sent to effector organ i.e., muscles which revel responses. Nerves needs assistance from the hormones because they cannot reach each and every part of the body. Coordination in humans is brought about by the secretions of endocrine glands. Endocrine glands are ductless glands which secrete chemical substances called hormones directly into the blood. An organ which responds to such a hormone is known as target organ. Hormonal control is mainly based on feedback mechanism and tells the body to either pace up or slow down; as per the situation. Nervous control, on the other hand, is more of a direct control. Both of them complement each other. Thus, it can be said that nervous and hormonal systems together perform the function of control and coordination in human beings.
