1.2.3 Annotate the structure of skeletal muscle IB Sports, exercise and health science Anatomy Topic 1 Anatomy 1.2.3 Annotate the structure of skeletal muscle Sub-topics Epimysium: connective tissue capsule. Perimysium: within the muscle tissue there is branching connective tissue called perimysium. Endomysium: the muscle cells themselves are individually wrapped in endomysium. Myofibril: the muscle cells are filled with cylindrical structures called myofibrils. These contain the myofilaments whose action is responsible for the contraction of the myofibrils and therefore the muscle as a whole. Solomon & Davis 1. The Skeletal System 2. The Muscular System

1.2.3 Annotate the structure of skeletal muscle IB Sports, exercise and health science Anatomy Topic 1 Anatomy 1.2.3 Annotate the structure of skeletal muscle There are 2 kinds of myofilaments: (Thick and Thin) Myosin: thick filaments Actin: thin filaments A unit of thick and thin filaments is known as a Sarcomere. These structures hold the key to muscle contraction. Because of the staggered thin and thick filaments it has the effect as one might pull a rope towards oneself hand over hand.

Insertion: the point where the tendon attaches to the bone which moves during an action. e.g. Action of biceps muscle: Scapula is origin (Proximal point) and radius is the insertion.
