Study Notes
Muscle Filaments and Contraction
- Actin filaments are responsible for muscle contraction.
Skeletal Muscle
- The main function of skeletal muscle is to move the body's skeleton.
- Skeletal muscle tissue can be voluntarily controlled.
Cardiac Muscle
- Cardiac muscle appears striated or striped due to the regular arrangement of its contractile units.
Muscle Contraction
- During muscular contraction, muscle fibers shorten.
Skeletal Muscle Structure
- The basic functional unit of skeletal muscles is the motor unit.
- The connective tissue that surrounds the entire skeletal muscle organ is epimysium.
- A bundle of several skeletal muscle fibers is known as a fascicle.
- The connective tissue surrounding each fascicle is called perimysium.
- The connective tissue that surrounds individual skeletal muscle fibers is endomysium.
- The cell membrane surrounding a skeletal muscle fiber is called sarcolemma.
- Skeletal muscle fibers contain multiple nuclei, not just one in the center.
