Translations
The scapula (shoulder blade) is a flat bone lying against the cranial part of the lateral thoracic wall.
The scapula presents:
The glenoid cavity, for the articulation with head of humerus, is located at the ventral angle of scapula. In horses, there is a craniomedial notch in the border of the glenoid cavity called the glenoid notch.
Cranially to the glenoid cavity is a large prominence, called the supraglenoid tubercle, for origin of the muscles of forearm. The coracoid process is a medial process on supraglenoid tubercle for origin of coracobrachial muscle; it remains small in domestic animals.
The infraglenoid tubercle is a small prominence at the caudal bordel dorsal to the ventral angle, for the origin of brachial triceps (carnivores and horses) and/or articularis humeri muscle (horses, cats and pigs).
