A system of human anatomy, general and special . ezoid ; and, examined from behind, it has a triangular form, the basebeing upwards ; hence another name, conoid. The interarticular fibro-cartilage is often indistinct, from havingpartial connexions with the fibro-cartilaginous surfaces of the twobones between which it is placed, and not unfrequently absent. Whenpartial, it occupies the upper part of the articulation. The synovialmembranes are very delicate. There is, of course, but one, whenthe fibro-cartilage is incomplete. Actions.—The acromio-clavicular articulation admits of two move- * The ligaments of the sterno-clavicular and costo-sternal articulations. 1. The ante-rior sterno-clavicular ligament. 2. The inter-clavicular ligament. 3. The costo-clavicu-lar or rhomboid ligament, seen on both sides. 4. The interarticular fibro-cartilage,brought into view by the removal of the anterior and posterior ligaments. 5. The anteriorcosto-stcrnal ligaments of the first and second ribs. 14* 162 LIGAMENTS OF THE SCAPULA—SHOULDER ments, the gliding of the surfaces upon each other ; and the rotationof the scapula upon the extremity of the clavicle. 3. The Proper ligaments of the ScapulaFis-82* are the Coraco-acromial,Transverse. The coraco-acromial ligament is abroad and thick triangular band, whichforms a protecting arch over the shoulderjoint. It is attached by its apex to thepoint of the acromion process, and byits base to the external border of thecoracoid process its whole length. Thisligament is in relation above with theunder surface of the deltoid muscle; andbelow with the tendon of the supra-spinatus muscle, a bursa mucosa beingusually interposed. The transverse or coracoid ligament isa narrow but strong fasciculus which crosses the notch in the upperborder of the scapula, from the base of the coracoid process, andconverts it into a foramen. The supra-scapular nerve passes throughthis foramen. 4. Shoulder Joint.—The scapulo-humeral articulation is an e
