Detailed explanation-1: -The superior border of the scapula extends from the superior angle to the coracoid process. The coracoid process is a hook-like structure that comes off anteriorly from the lateral superior aspect of the ventral side of the scapula. Like the acromion, it is an attachment point for muscles and ligaments.
Detailed explanation-2: -The muscles that are attached are: Pectoralis Minor, Coracobrachialis, and Biceps Brachii. In addition, this structure attaches all the tendons and ligaments together.
Detailed explanation-3: -Levator scapulae muscle – they insert into the superior angle and medial border (superior to the spine). Their roles are to elevation the scapula. They are innervation by branches of C3-C5.
Detailed explanation-4: -Coracoclavicular Ligament. The coracoclavicular ligament, which connects the distal end of the clavicle to the coracoid process, functions to help stabilize the acromioclavicular joint. It is made up of two separate bundles, the trapezoid and conoid ligaments.
