Understand the anatomy of the scapula: The scapula, or shoulder blade, is a triangular bone that connects the humerus (upper arm bone) with the clavicle (collarbone). It has several important landmarks, including the spine, acromion, inferior angle, glenoid cavity, and coracoid process.
Focus on the spine of the scapula: The spine is a prominent ridge running across the posterior surface of the scapula. It serves as an attachment point for muscles and divides the scapula into the supraspinous and infraspinous fossae.
Learn about the acromion: The acromion is a bony projection at the lateral end of the spine of the scapula. It forms the highest point of the shoulder and articulates with the clavicle at the acromioclavicular joint.
Relate the spine to the acromion: The spine of the scapula is continuous with the acromion, meaning the acromion is an extension of the spine that projects outward to form part of the shoulder structure.
Review the other options: The inferior angle is the bottom-most point of the scapula, the glenoid cavity is the socket for the humerus, and the coracoid process is a hook-like projection on the anterior side of the scapula. None of these are directly continuous with the spine of the scapula.
