N-H Coordination

Body coordination is important to help us avoid injuries as well as adapt to changes around us. As the parts of our body communicate in unison with each other, a series of movements occurs in response to a stimulus.

There are two types of body coordination; nervous coordination and hormonal coordination.

The nervous system generates fast responses while the hormonal system generates slow and long responses.

Nervous Coordination
The centrel nervous sytem is the control centre of the body, where impulses are received and interpreted, and response impulses are sent to the relevant parts of the body for the appropriate responses.

The central nervous system communicates through electrical impulses, which are transmitted through interconnecting nerve cells.

Hormonal Coordination
The hormonal system consists of the endocrine glands, which secrete hormones. The blood system is involved in ensuring that hormones reach the target areas. The responses are usually projected in the form of growth, which is a slow response.
