Our brain is in control of many very important body functions and sensations like these for example: sleep‚ muscle movement‚ memory‚ sexual activity‚ emotions‚ hunger and thirst.

Endocrine Vs Nervous System The endocrine system acts with nervous system to coordinate the body’s activities. Both systems enable cells to communicate with others by using chemical messengers. The endocrine system uses chemical messengers called hormones that are transported by the circulatory system (blood). They act on target cells that may be anywhere in the body. The endocrine system is slower than the nervous system because hormones must travel through the circulatory system to reach their
