Muscular Fascia Kailey H, Colleen, Melanie

Muscular Fascia § Creates structural organization of a muscle § Tough fibrous fascia connective tissue § Also known as deep fascia

Components § Major component Collagen fibers § Minor component Elastin fibers

Names and Locations § Endomysium Fibrous fascia surrounding individual muscle fibers § Perimysium surrounds a group of muscle fibers § Divides muscles into bundles Fascicles § Epimysium surrounds the entire muscle

Function of Muscle Fascia § All three layers blend together to continue beyond the muscle to attach muscle to bone § Role of fascia attachment is to transfer the force of the muscle contraction to the bone § Lateral force transmission

Lateral Force Transmission § These three layers of fascia serve to bind fibers together laterally § Ex: § Fibers A and B are next to each other § A fires and B does not § But the contraction of A transfers to B and causes a pulling force even though B was not stimulated to fire § Therefore causing B to contract with A

Shapes § Tendon The muscular fascia that attaches the muscle to a bone is round and cordlike § Aponeurosis The muscular fascia is broad and flat

Question 1 What are three types of fibrous fascia?

Answer § Endomysium § Perimysium § Epimysium

Question 2 What is called when adjacent fibers contract without being stimulated?

Answer Lateral Force Transmission

Question 3 What is the muscular fascia attached to the bone that is round and cordlike?

Answer §Tendon
