Every skeletal muscle in your body is made up of hundreds of thousands of tiny muscle fibers (or muscle cells).
Each muscle fiber is wrapped in a connective tissue sheath, called an endomysium.
Several muscle fibers gathered together into a bundle are called a muscle fascicle.
Each fascicle is wrapped in a collagen sheath, called a perimysium.
Many muscle fascicles together make up the whole muscle, which is wrapped in a connective tissue sheath, called the epimysium.
Each skeletal muscle fiber has a nerve ending that controls its activity, an artery and one or more veins.
The muscles are wrapped in a connective tissue deep fascia sheet that binds them into functional groups.
The muscle connects to the bone via a tendon.
