4. اتصال عضلات اسکلتی
As the muscle contracts, one of the bones moves relative to the other joint. The more fixed, or stationary, attachment is designated as the origin of a muscle, whereas the movable end is its insertion. The fleshy, thickened portion of a muscle is referred to as its belly, or gaster. Usually the belly of a muscle is located on the proximal bone that is to be moved. The joint is spanned by a tendon from the muscle. A tendon is toughened, dense fibrous connective tissue that connects a muscle to the periosteum of a bone.

5. نحوه عملکرد عضلات اسکلتی
1. When muscle cells contract they pull producing tension. 2. Tension applied to an object tends to pull the object to the tension. Resistance is a passive force that opposes the movement. 4. Compression, or a push applied to an object, tends to force the object away from the source of compression Muscles that contract together and are coordinated in accomplishing a particular movement are said to be synergistic synergistic. Antagonistic muscles perform opposite functions and are generally located on the opposite sides of the limb Example-Biceps contract together (flex) and the triceps extend (relaxes).
