The lateral third has two surfaces, an upper and a lower; and two borders, an anterior and a posterior.
The clavicle articulates with the sternum at the sternoclavicular joint medially, and with the acromion process of the scapula at the acromioclavicular joint laterally.
The sternoclavicular joint is formed by the medial end of the clavicle and the sternum, while the acromioclavicular joint is formed by the lateral end of the clavicle and the acromion process of the scapula.
clavicle (collarbone). The conoid tubercle is a small bump on the inferior surface of the clavicle where the conoid ligament attaches. The costal tuberosity is a roughened area on the medial aspect of the clavicle where the costoclavicular ligament attaches.
The most superior medial aspect of the scapula is called the superior angle.
The clavicle. This bone is normally not consideredto be part of the shoulder an instead a part of the thorax, which is also true. The reason it is part of the shoulder is that it joint part of the scapula to form the soked of the glenohumeral joint.
Acromion process and sternum
Yes, the clavicle is medial to the humerus. The clavicle (collarbone) is located more towards the center of the body, whereas the humerus (upper arm bone) is located more towards the side of the body.
The clavicle articulates with the sternum at the sternoclavicular joint medially, and with the acromion process of the scapula at the acromioclavicular joint laterally.
The sternoclavicular joint is formed by the medial end of the clavicle and the sternum, while the acromioclavicular joint is formed by the lateral end of the clavicle and the acromion process of the scapula.
Medial end
The medial epicondyle is the most medial structure on the humerus. It serves as an attachment site for muscles and ligaments of the forearm.
clavicle (collarbone). The conoid tubercle is a small bump on the inferior surface of the clavicle where the conoid ligament attaches. The costal tuberosity is a roughened area on the medial aspect of the clavicle where the costoclavicular ligament attaches.
The most superior medial aspect of the scapula is called the superior angle.
the medial end articulates with the sternum and the distal end articulates with the humerus and scapula.
The clavicle. This bone is normally not consideredto be part of the shoulder an instead a part of the thorax, which is also true. The reason it is part of the shoulder is that it joint part of the scapula to form the soked of the glenohumeral joint.
The medial border of the scapula is at the medial end of the spine of the scapula. This border is also called the vertebral border.
The spine is a medial structure. It lies in the midline of the body.
