Microscopic anatomy of skeletal muscle
Perimysium
Connective tissue surrounding a fascicle
Sacromere
Contractile unit of muscle
Sarcolemma
Plasma membrane of the muscle cell
Myofilament
Thick and thin. Constructed from proteins, principally myosin or actin.
Endomysium
Thin connective tissue investing each muscle cell
Fascicle
a discrete bundle of muscle cells
Muslce Fiber
a muscle cell (myocyte)
Epimysium
connective tissue ensheathing the entire muscle
Tendon
cordlike extension of connective tissue beyond the muscle,serving to attach it to the bone
Myofibril
elongated contractile threads found in striated muscle cells. Several sarcomeres lined up end to end
