7
Q
Smooth (Visceral) Muscle
A
- makes up walls of hollow organs
- walls of ducts, bronchioles, and blood vessels
- muscle operates involuntarily
- responsible for peristalsis of digestive system
8

- functions involuntarily: pumping the heart
9
Q
Skeletal Muscle
A
- Attached to bones of skeleton
- maintains posture
- maintains large proportion of body heat
- voluntary system
10
Q
Muscle Action
A
- Muscle works in pairs to produce movement
- Prime mover contracts: the antagonist must relax
- Beginning and end of a muscle
- Muscles composed of individual cells - fibers, held together in bundles by connective tissue
- Covering muscle is fascia - connective tissue that covers a muscle
- Tendon attaches muscle to bone
11
Q
Prime Mover
A
