Elbow Joint Anatomy Video Lecturio Medical The upper arm is located between the shoulder joint and elbow joint. it contains four muscles – three in the anterior compartment (biceps brachii, brachialis, coracobrachialis), and one in the posterior compartment (triceps brachii). in this article, we shall look at the anatomy of the muscles of the upper arm – their attachments. The shoulder joint (glenohumeral joint) is an inherently unstable joint, and thus requires a significant degree of muscular support in the form of the rotator cuff. the shoulder is most unstable in extension and external rotation. it most commonly dislocates anteriorly (95%), and can damage the axillary nerve.
Elbow Joint Anatomy Video Lecturio Medical The shoulder joint, also known as the glenohumeral joint, is a ball and socket joint with the most extensive range of motion in the human body. the shoulder muscles have a wide range of functions, including abduction, adduction, flexion, extension, internal and external rotation.[1] the central bony structure of the shoulder is the scapula, where all of the muscles interact. at the lateral. 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. like most synovial joints, the articulating surfaces are covered with hyaline cartilage. the head of the humerus is much larger. Bones, ligaments, muscles and movements of the shoulder joint. the glenohumeral, or shoulder, joint is a synovial joint that attaches the upper limb to the axial skeleton. it is a ball and socket joint, formed between the glenoid fossa of scapula (gleno ) and the head of humerus ( humeral). acting in conjunction with the pectoral girdle, the. The glenohumeral joint is structurally a ball and socket joint and functionally is considered a diarthrodial, multiaxial, joint.[1] the glenohumeral articulation involves the humeral head with the glenoid cavity of the scapula, and it represents the major articulation of the shoulder girdle.[2] the latter also includes minor articulations of the sternoclavicular (sc), acromioclavicular (ac.
