HUMAN NUTRITION

Detailed explanation-1: -Human behavior, in all its complexity, is partly the product of interactions between two key physical components: the nervous and endocrine systems. These two systems help regulate the electrical and chemical processes that relay information throughout and between the brain and body.

Detailed explanation-2: -Median nerve. The median nerve supplies muscles that help bend the wrist and fingers. It is a main nerve for the muscles that bend the thumb. The median nerve also gives feeling to the skin on much of the hand around the palm, the thumb, and the index and middle fingers.
