Structure of Skeletal Muscle
- Skeletal muscle is organized into muscle cells, bundles of cells, and connective-tissue coverings that transmit force.
- Muscle cells in skeletal muscle are also called muscle fibers because they are long and fiber-like.
- Connective tissue around skeletal muscle carries blood vessels and nerves while helping transmit contraction force.
- Force transmission is necessary because contraction inside muscle fibers must be transferred to tendons, bones, or other muscles.
