Human Movement

Humans can move from one place to another through coordinated movements and postures. The movement produced by the human body due to the contraction of muscles and bending of bone joints is called human movement. Human movements are controlled by the nervous system. Hence, the human movement incorporates the use of muscles, ligaments, joints, and bones.  Kinesiology is the field that deals with the study of human movements.
