It is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula. It is directed laterally and forward and articulates with the head of the humerus; it is broader below than above and its vertical diameter is the longest. This cavity forms the glenohumeral joint along with the humerus.

2021年9月6日 · Glenoid fossa – It is a shallow pyriform cavity located at the lateral angle of the scapula. It articulates with the rounded head of the humerus, forming the glenohumeral (shoulder) joint. Supraglenoid tubercle – It is a small rough projection located immediately above the glenoid fossa near the base of the coracoid process.

2023年10月30日 · The glenohumeral joint is the articulation between the spherical head of the humerus and the concave glenoid fossa of the scapula. Being a synovial joint, both articular surfaces are covered with hyaline cartilage. The glenoid fossa is a shallow pear-shaped pit on the superolateral angle of scapula. The concavity of the fossa is less acute than ...

2024年10月8日 · The shoulder joint is formed by an articulation between the head of the humerus and the glenoid cavity (or fossa) of the scapula. This gives rise to the alternate name for the shoulder joint – the glenohumeral joint.

2023年8月8日 · The glenohumeral joint is a ball and socket joint that includes a complex, dynamic, articulation between the glenoid of the scapula and the proximal humerus. Specifically, it is the head of the humerus that contacts the glenoid cavity (or fossa) of the scapula.

2024年10月1日 · The scapula has two main articulations: Glenohumeral joint – between the glenoid fossa of the scapula and the head of the humerus. Acromioclavicular joint – between the acromion of the scapula and the clavicle.

2023年7月24日 · The lateral angle of the scapula is the location of the glenoid cavity; this is where the humeral head articulates with the scapula. At the margins of this cavity, a fibrocartilagenous structure called the glenoid labrum acts to deepen the …

On the lateral border of the scapula is a shallow pyriform, articular surface, the glenoid cavity, which is directed lateralward and forward and articulates with the head of the humerus; it is broader below than above and its vertical diameter is the longest.

2023年7月24日 · The humeral head articulates with the glenoid fossa of the scapula. It is a shallow articulation, as the fossa accommodates less than one-third of the humeral head. The labrum, a fibrocartilaginous ring, attaches to the outer rim of the glenoid fossa and provides additional depth and stability securing the humeral head.

The glenoid fossa is a shallow, cup-shaped depression on the lateral aspect of the scapula that forms the socket portion of the shoulder joint, or glenohumeral joint. It serves as the articulation point for the head of the humerus bone, allowing for a wide range of motion in the upper limb.
