Study Notes

Pectoral Girdle Bones

The pectoral girdle consists of the scapulae and clavicles.

Connection to Axial Skeleton

The clavicle is directly attached to the axial skeleton.

Scapula Mobility

The scapula is able to move freely due to the presence of the sternoclavicular joint and the acromioclavicular joint.

Pectoral Girdle Function

The function of the pectoral girdle is to provide a base of attachment for the muscles of the upper limb.

Bone Identification

The clavicle is commonly known as the collarbone.
The scapula is commonly known as the shoulder blade.

Ligaments and Attachments

The costoclavicular ligament attaches to the first rib.
The coracoclavicular ligament is made up of the trapezoid ligament and the conoid ligament.
The supraspinatus muscle attaches to the supraspinous fossa of the scapula.
The levator scapulae muscle attaches to the superior angle of the scapula.
The rhomboid muscle attaches to the medial border of the scapula.

Landmarks and Palpation

The coracoid process can be located by following the clavicle laterally.
The acromion is located on the lateral border of the scapula.
The inferior angle of the scapula can be palpated with the patient in a standing position.
The triceps brachii muscle can be palpated with the patient in a relaxed position.

Joints and Articulations

The humerus articulates with the scapula at the glenohumeral joint.
The clavicle articulates with the acromion of the scapula at the acromioclavicular joint.

Bone Characteristics

The clavicle is a long bone.
