The Pectoral Girdle Flashcards
The Scapula
Shoulder blade bone located on the posterior side of the shoulder
Clavicle
collarbone; elongated bone that articulates with the manubrium of the sternum medially and the acromion of the scapula laterally
Pectoral Girdle
shoulder girdle; the set of bones, consisting of the scapula and clavicle, which attaches each upper limb to the axial skeleton
Sternal End of Clavicle
Medial end of the clavicle that articulates with the manubrium of the sternum
Sternoclavicular Joint
Articulation between the manubrium of the sternum and the sternal end of the clavicle; forms the only bony attachment between the pectoral girdle of the upper limb and the axial skeleton
Costiclavicular Ligament
Band of connective tissue that unites the medial clavicle with the first rib
Acromial End if Clavicle
Lateral end of the clavicle that articulates with the acromion of the scapula
Superior Border of Scapula
Superior margin of scapula
Medial Border of Scapula
Elongated, medial margin of the scapula
Lateral Border of Scapula
Diagonally oriented lateral margin of the scapula
Suprascapular Notch
Small notch located along the superior border of the scapula, medial to the Coracoid process
Superior Angle of Scapula
Corner of the scapula between the superior and medial borders of the scapula
Inferior Angle of Scapula
Inferior corner of the scapula located where the medial and lateral borders meet
Glenoid Cavity
shallow depression locates on the lateral scapula, between the superior and lateral borders
Glenohumeral Joint
Shoulder joint; formed by the articulation between the glenoid cavity of the scapular and the head of the humerus
Supraglenoid Tubercle
Small bump located at the superior margin of the glenoid cavity
Infraglenoid Tubercle
small bump or roughened area located on the lateral border of the scapula, near the inferior margin of the glenoid cavity
Coracoid Process
Short, hook like process that projects anteriorly and laterally from the superior margin of the scapula
Spine of the Scapula
Prominent ridge passing mediolaterally across the upper portion of the posterior scapular surface
Acromion
flattened bony process that extends laterally from the scapular spine to form the bony tip of the shoulder
Acromioclavicular Joint
Articulation between the acromion of the scapula and the acromial ens of the clavicle
Fossa
Shallow depression on the surface of a bone
Supraspinous Fossa
Narrow depression locates in the posterior scapula, superior to the spine
Infraspinous Fossa
Boras depression locates on the posterior scapula, inferior to the spine
Subscapular Process
Coracoclavicular Ligament
Strong band of connective tissue that anchors the Coracoid process of the scapula to the lateral clavicle; provides important indirect support for the acromioclavicular joint
