Scapula: The scapula

The scapula , commonly known as the shoulder blade, is a flat, triangular-shaped bone that provides a vital part of the shoulder girdle. It serves as an attachment site for several muscles that facilitate the shoulder's complex movements. Structurally, it features a body, two processes (the acromion and the coracoid process), and a glenoid cavity, which articulates with the humerus to form the shoulder joint. The scapula is also known as the shoulder blade. It articulates with the humerus at the glenohumeral joint, and with the clavicle at the acromioclavicular joint. In doing so, the scapula connects the upper limb to the trunk. Learn about the scapula , a triangular bone that forms part of your shoulder joint and connects your arm to your trunk. Find out how it works, what can go wrong and how to keep it healthy. The scapula , commonly known as the shoulder blade, is a large, flat, triangular bone located in the upper back that connects the humerus (upper arm bone) with the clavicle (collarbone). Its main anatomical parts include three borders (superior, medial, and lateral), three angles (superior, inferior, and lateral), and prominent processes like the acromion, spine, and coracoid process. It also has key surfaces like the subscapular fossa (anterior) and the supraspinous and infraspinous fossae ...
