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
