The Muscular System 1. Muscles are responsible for all types of body movement Three basic muscle types are found in the body –Skeletal muscle –Cardiac.
MUSCLES. 40-45 % of body mass only system converting chemical energy into mechanical 2 types -skeletal (striated) -smooth.

Excitation–Contraction Coupling Action potential reaches a triad: Action potential reaches a triad: –releasing Ca 2+ –triggering contraction Requires myosin.
Muscle Contraction The role of skeletal muscle is to aid in movement and maintain posture. In order to do this it must contract. Twitch: a brief mechanical.
