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.
