Muscular System & Homeostasis stabilize body position produce movements regulate organ volume move substances w/in the body produce heat

Muscular System includes 700 voluntary muscles combination muscle & CT

Skeletal Muscle almost all cross a joint when contract extend force on tendon  pulls on one of articulating bones usually, 1 bone remains stationary or near its original position & other bone moves – muscle whose tendon is attached to stationary bone = origin – muscle whose tendon is on moving bone = insertion

Skeletal Muscle fleshy part of muscle = belly (gaster)

Relationship of Skeletal Muscle to Bones: Lever Systems

3 Types Levers in Human Body

How Muscles are Named see handout – know “basics of naming muscles” – be able to identify what region or part of body any of listed muscle are located – know names of highlighted muscles
