Pectoral Girdle Anatomy and Functions

Dr. Benado explains the anatomy of the pectoral girdle, focusing on the clavicle and scapula. The clavicle connects the upper limbs to the axial skeleton, articulating with the sternum and scapula. The scapula's features, including the spine, supraspinous and infraspinous fossae, and the glenoid fossa, are detailed. The video also highlights common student confusions between the coracoid process and acromion, offering mnemonic aids for better understanding.
