The sternocleidomastoid muscle originates from two locations&colon; the manubrium of the sternum and the clavicle. The pectoralis major can be targeted from numerous training angles along the sternum and clavicle. Medially, it articulates with the manubrium of the sternum (breastbone) at the sternoclavicular joint. Pectus carinatum is an overgrowth of costal cartilage causing the sternum to protrude forward. He sustained a cracked sternum and shoulder injuries. Located at the inferior end of the sternum is the pointed xiphoid process. He dealt with a costochondral fracture (fractured cartilage connecting the rib to the sternum). Its origin is the xiphoid process of the sternum. It consists of the ribs and sternum. A fracture of the sternum is usually a comminuted fracture. Nicks, segmenting, and fracturing of the sternum and ribs all defended this. Ribs are described based on their location and connection with the sternum. Sternocephalicus&colon; originates on the sternum and inserts on the temporal bone of the head. Sternohyoideus&colon; originates on the sternum and inserts on the basihyoid bone. Fractures of the sternum are rather uncommon.
