What is the histologic organization of skeletal muscle?
Skeletal muscle is composed of long, thin, cylindrical, multinucleated cells called muscle fibers (or myofibrils).
Each fiber has a motor endplate at its neuromuscular junction and is surrounded by connective tissue called endomysium .
Groups of fibers, or a fascicle, are surrounded by a connective tissue layer called the perimysium .
Fascicles are grouped together and surrounded by epimysium.
