Skeletal muscle
Most skeletal muscle fibers are attached by tendons to bones
Skeletal muscle cells are large, cigar-shaped, and multinucleate
Also known as striated muscle because of its obvious stripes
Also known as voluntary muscle because it is the only muscle tissue subject to
conscious control
Skeletal muscle cells are surrounded and bundled by connective tissue
Endomysium: Encloses a single muscle fiber
Perimysium: Wraps around a fascicle (bundle) of muscle fibers
Epimysium: Covers the entire skeletal muscle
Fascia: On the outside of the epimysium
The epimysium of skeletal muscle blends into a connective tissue attachment
Tendons: Cordlike structures
Mostly collagen fibers
Often cross a joint because of their toughness and small size
