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.
