The bones of the skeletal system provide a framework for the muscles of the muscular system to work against, promoting motion within the organism itself. Take your biceps muscle, the top part of your upper arm, the one we flex when trying to show off how big our muscles are. When that muscle contracts, which means to get shorter, it pulls on the lower arm to cause it to come closer to the body. It is attached to the bones by means of tendons. thick elastic tissue that binds the end of the muscle to a connection point on the bone. Ligaments are similar in composition to tendons, but they differ in function. Ligaments bind bone to bone in junctions in the skeleton called joints. When the biceps muscle relaxes, the muscle on the other side of the upper arm contracts and causes the lower arm to extend. Muscles that cause limbs to extend are called extensors, while those that cause limbs to come in closer to the body are called flexors.
○ BONES = it is solid non flexible connective tissue, it forms framework of the body and protects organs from damage
○ MUSCLES = The main framework of the body (skeleton) is covered by muscles, whose function is to permit movement and maintain posture
○ TENDONS = They connect muscle to the bone
○ LIGAMENTS = they connect bone to bone
TENDON CONNECT THE MUSCLES TO THE BONE
