Differentiate between chemical coordination and nutral coordination
Answers
Answer:
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.
Chemical Coordination
Chemical coordination is under the control of endocrine system of body which consists of different glands at various locations of body. There are a total of 20 glands in the body. These glands secrete different chemicals called hormones which have got several functions depending upon their origin. E.g. thyroid gland in neck and which is responsible for regulation of metabolism and adrenal gland in the lumbar region which regulate heart rate. Every hormone has different site and duration of action.
Answer:
In contrast to chemical coordination, the nervous system coordinates functions in the animal body on a more localized level as it delivers nerve impulses to contract body muscles or regulate gland activities.
