THE SHOULDER JOINT 121 The trapezoid ligament {lig. trapezoideum) is attached, inferiorly,to the basal half of the superior surface of the coracoid process andsuperiorly to the inferior surface of the acromial end of the clavicle. The conoid ligament (lig. conoideum) is somewhat triangular; itsblunt apex is attached to the base of the coracoid process (near thescapular notch) and its base is attached to the coracoid tuberosity ofthe clavicle. It lies medial to the preceding ligament.

The scapula has several intrinsic ligatnents that are not coracoacromial ligament {lig. coracoacromiale) is attached, in-feriorly, to the apical half of the dorsolateral margin of the coracoidprocess and, superiorly, to the tip of the acromion. It is tense andtends to protect the shoulder joint. The superior transverse ligament (lig. transversum scapulce superius)bridges the scapular notch. The inferior transverse scapidar ligament connects the lateralmargin of the scapular spine with the dorsal aspect of the head ofthe scapula. THE SHOULDER JOINT (ARTICULATIO HUMERI) The shoulder joint is of the enarthrodial variety and permits of thewidest range of movement of any joint of the body. It is formed bythe glenoid fossa of the scapula and the head of the hum
