Skeletal Muscle Structure

Myosatellite cells

stem cells that function in the repair of damaged muscle tissue

endomysium

thin layer of areolar connective tissue that surrounds each muscle fiber. Loosley interconnects nearby muscle fibers

skeletal muscle fibers

contains capillaries, myosatellite cells, and the axons of the neurons that control the muscle fibers.

tendon

attaches the muscle to a specific point on a bone.

Muscle fascicles

bundles of muscle fibers

Epimysium

dense layer of collagen fibers, surrounds the entire muscle. separates the muscle from surrounding tissues and organs. It is connected to the deep fascia, a dense connective tissue layer

Perimysium

fibrous layer that divides the skeletal muscle into a series of compartments.

aponeurosis

provides attachment over a broad area that may involve more than one bone.
