Verified step by step guidance

Identify the anatomical structure being asked about: The question is asking for a bony projection on the scapula that serves as a muscle attachment site.
Review the anatomy of the scapula: The scapula, or shoulder blade, has several prominent features, including the coracoid process, acromion, and spine of the scapula. Focus on the coracoid process as it is a key projection.
Understand the function of the coracoid process: The coracoid process is a hook-like bony projection on the anterior surface of the scapula. It serves as an attachment site for muscles such as the pectoralis minor, coracobrachialis, and the short head of the biceps brachii.
Eliminate incorrect options: The radial tuberosity is located on the radius and serves as an attachment site for the biceps brachii tendon. The olecranon process is part of the ulna and forms the elbow's bony prominence. The medial epicondyle is a projection on the humerus, not the scapula.
Conclude that the correct answer is the coracoid process, as it is the only option that matches the description of a bony projection on the scapula serving as a muscle attachment site.
