2024年10月8日 · The shoulder joint (glenohumeral joint) is an articulation between the scapula and the humerus. It is a ball and socket -type synovial joint, and one of the most mobile joints in the human body. In this article, we shall look at the anatomy of the shoulder joint – its structure, blood supply, and clinical correlations. Premium Feature. 3D Model.
Glenohumeral (Shoulder) joint: Bones, movements, muscles
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.
How Your Shoulder Joint Works - Cleveland Clinic
Your shoulder is made up of two joints that connect the three bones of your shoulder together with soft tissue, muscle, tendons, ligaments and cartilage. The three bones in your shoulder are your: Shoulder blade (scapula). Collarbone (clavicle). Upper arm bone (humerus).
Shoulder Joint Anatomy & Function - Shoulder Pain Explained
Scapula: shoulder blade. The glenohumeral joint is a ball and socket joint. The “ball” is formed by the head of humerus, a hemispherical portion that angles out and up from the top of the humerus towards the body. The “socket” is formed by a concave depression on the upper, outer border of the scapula, known as the glenoid cavity or glenoid fossa.
Scapulohumeral Rhythm - Physiopedia
Scapulohumeral Rhythm. It describes timing of movement at glenohumeral and scapulothoracic joint during shoulder elevation. First 30 degrees of shoulder elevation involves a "setting phase": The movement is largely glenohumeral. Scapulothoracic movement is small and inconsistent.
Anatomy, Shoulder and Upper Limb, 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. The articulating surfaces of both have a lining of articular cartilage.
Anatomy, Shoulder and Upper Limb, Scapulohumeral Muscles
2023年5月19日 · The scapulohumeral muscles dynamically position the glenoid properly in the glenohumeral socket and are vital for the function of the glenohumeral joint. They coordinate the motion of the scapula and humerus to allow efficient movement to take place. The motion of these two joints is quantifiable with scapulohumeral rhythm (SHR).
Glenohumeral Joint - Physiopedia
The glenohumeral (GH) joint is a true synovial ball-and-socket style diarthrodial joint that is responsible for connecting the upper extremity to the trunk. It is one of four joints that comprise the shoulder complex. This joint is formed from the combination of the humeral head and the glenoid fossa of the scapula.
The Intrinsic Muscles of the Shoulder - TeachMeAnatomy
2024年9月28日 · The intrinsic muscles (also known as the scapulohumeral group) originate from the scapula and/or clavicle, and attach to the humerus. There are six muscles in this group – the deltoid, teres major, and the four rotator cuff muscles (supraspinatus, infraspinatus, subscapularis and teres minor). Deltoid.
Shoulder - Physiopedia
Comprising numerous ligamentous and muscular structures, composed of the clavicle, scapula, humerus and sternum, and an intricately designed combination of four joints, the Glenohumeral (GH) Joint, the Acromioclavicular (AC) Joint and the Sternoclavicular (SC) Joint, and a "floating joint", known as the Scapulothoracic (ST) joint.
