Document Summary

Myology - study of the muscular system. Constitute about of our body weight. 3 kinds of muscle tissue = cardiac, smooth, skeletal (muscle fiber) Muscles designed to serve 1 primary purpose = converting chemical energy in atp high energy phosphate bonds into the mechanical energy of motion. Move from place to place, movement of body parts and body contents in breathing, circulation, feeding and digestion, defecation, urination, and childbirth. Supports communication=speech, writing, and nonverbal communications (birds) Holding some joints in place by maintaining tension on tendons (opposing antagonistic muscles) Antigravity muscles - resist pull of gravity and prevent us from falling or slumping over. Sphincters - internal muscular rings that control flow of materials in, out, or through the body (ex. Movement of food, bile, blood, and other materials) Some made out of smooth muscle, some made out of skeletal muscle. As much as 85% of our body heat (majority of body heat comes from.
