Study Notes
Skeletal Muscle
- Enables movement of the body by contraction and relaxation
Muscle Characteristics
- Smooth muscle: contraction speed is slow (non-striated, involuntary control)
- Skeletal muscle: under voluntary control, striated, central nucleus
Muscle Functions
- Main function of the muscular system: movement, support, and protection of the body
- Main function of smooth muscle: contraction and relaxation of hollow organs and blood vessels
Muscle Anatomy
- Deep fascia: structure that separates muscles from skin, contains adipose tissues
- Skeletal muscle: accounts for approximately 40% of total body weight
Muscle Response
- Skeletal muscle: has the ability to respond to stimuli by producing electrical signals
