BIO210Y5 Chapter Notes - Chapter 8: Shoulder Girdle, Bicipital Groove, Spine Of Scapula
Document Summary
7. 14 the appendicular skeleton includes the limb bones and the pectoral and pelvic. The appendicular skeleton includes the bones of the limbs and the supporting bone girdles that connect them to the trunk. 7. 15 the pectoral girdles the clavicles and scapulae connect the upper limbs to. Each arm articulates (forms a joint) with the trunk at the pectoral girdle, or shoulder girdle: the pectoral girdle consists of two s-shaped clavicles and two broad, flat scapulae. The lateral angle of the scapula forms a broad process that supports the cup-shaped glenoid cavity: at the glenoid cavity, the scapula articulates with the humerus, the proximal bone of the upper limb, forming the glenohumeral joint. The anterior surface of the body of each scapula forms a broad, smooth triangle: the corners of the triangle are called the superior angle and the inferior angle. The acromion is continuous with the scapular spine.
