Muscle Tissue Structure Comparison
- Compare and contrast skeletal, cardiac, and smooth muscle tissue relative to structure, body location, and specific function.
- Structure:
- Skeletal muscle has long, cylindrical fibers with striations and multiple nuclei located peripherally.
- Cardiac muscle, also striated, has branching fibers with a single central nucleus, and its striations are less prominent than in skeletal muscle.
- Smooth muscle lacks striations and consists of spindle-shaped cells with a single nucleus.
- Location:
- Skeletal muscle is attached to bones, controlling voluntary movements.
- Cardiac muscle is found only in the heart, responsible for pumping blood.
- Smooth muscle lines the walls of hollow organs, such as blood vessels and the digestive tract, facilitating involuntary movements like peristalsis and vasoconstriction.
- Function:
- Skeletal muscle is responsible for voluntary movements, posture, and joint stability.
- Cardiac muscle maintains rhythmic contractions to circulate blood.
- Smooth muscle moves substances through various organs, such as food through the digestive system or blood through vessels, often through slow, sustained contractions…
