Question

5 differences between chemical coordination and neural coordination

Answer 1

Nature has designed human body in a different way. It consists of organs which are under control of brain and peripheral systems. This regulation of internal system of body is termed as ‘homeostasis’. Its examples include maintenance of a constant level of water in body and a constant temperature of body. In humans, Nervous and chemical coordination are two basic components of regulation of organs. Both these systems function simultaneously to control various functions of body like movement, thinking and emotions. Both of these systems sense changes in the external environment and adjust internal environment accordingly to avoid harm to the body organs.

Nervous Coordination

Human nervous system has got two divisions, central and peripheral nervous systems. Central nervous system comprises of brain and spinal cord. Brain is divided into three parts and it receives signals from spinal cord, gets those signals interpreted and then sends signals for action according to the input signals back to the body through spinal cord e.g. if we touch a hot object, signals travel through spinal cord to brain and brain orders the touching part to withdraw immediately but all this process occurs in milliseconds.
