Bone still cartilaginous. The following steps are followed in the conversion of cartilage to bone: Bones have a variety of functions: Bones serve a variety of mechanical functions. Together the bones in the body form the skeleton. They provide a frame to keep the body supported, and an attachment point for skeletal muscles, tendons, ligaments and joints, which function together to generate and transfer forces so that individual body parts or the whole body can be manipulated in three-dimensional space (the interaction between bone and muscle is studied in biomechanics). Bones protect internal organs, such as the skull protecting the brain
Sternocleidomastoid muscle result from birth trauma that gives rise to a mass or tumor that can be palpated within the muscle. It is given the name "sternocleidomastoid" because it originates at the manubrium of the sternum ("sterno-") and the clavicle ("cleido-"), and has an insertion at the mastoid process of the temporal bone of the skull. Sternocleidomastoid muscle The sternocleidomastoid muscle is one of the largest and most superficial cervical muscles. The primary actions of the muscle are rotation of the head to the opposite side and flexion of the neck. The sternocleidomastoid is innervated by the accessory nerve. It is given
