Study Notes
Skeletal Muscle Structure
- Skeletal muscle cells are elongated and known as myofibers
- Each myofiber contains many nuclei (100-300)
- The nuclei in a myofiber are located on the periphery of the cell
- Myofibers are arranged in parallel and do not branch
- Connective tissue is present between myofibers
- The cytoplasm, or sarcoplasm, of a myofiber contains many myofibrils
- The presence of myofibrils creates a striation pattern in skeletal muscle
