Skeletal Muscle Anatomy Human Anatomy and Physiology

Skeletal Muscle Anatomy The reason skeletal muscles are not ripped apart as they exert force is that thousands of their fibers are bundled together by connective tissue, which provides strength and support to the muscle as a whole.

Skeletal Muscle Anatomy Each muscle fiber is enclosed in a delicate connective tissue sheath called an endomysium. Several muscle fibers are then wrapped by another membrane called a perimysium to form a bundle Many fascicles are bound together by an overcoat of connective tissue called an epimysium, which covers the entire muscle.

Skeletal Muscle Anatomy These epimysium blend into the tendons, which attach muscles indirectly to bones, cartilages, or connective tissue coverings of each other.
