Glenohumeral Joint

Glenohumeral crossroads In this essay we will cover the functions and anatomical body structure of the glenohumeral roast and synovial give voice while to a fault looking at what components are used to brace the glenohumeral sound out. The glenohumeral reefer (articulatio humeri conjunction) is probably the closely complex vocalise in the entire human body. Its alter joint supplies the humerus with a full range of movement in all axes and planes. This joint offers many joint movements such as; flexion, extension and hyperextension, adduction and abduction, horizontal flexion and horizontal extension, circumduction and rotation. This type of joint is one of half dozen synovial joints called the ball and socket joint. A synovial joint is a freely moveable joint with classifiable features. They all micturate a smooth cartilage book binding the ends of the atomic number 76 up and a double social classed capsule which encloses the joint cavity. The outer story is toug h and is used for protection against luxuriant movement in lots of directions, while the inner layer is used to release synovial fluid to help be the joint during motion. This part of the capsule is known as the synovial membrane. Synovial fluid may also cherry-reduce red by destroying cellular debris by releasing peculiar(a) face cloth blood cells.

The glenohumeral joint is composed of three bones; the clavicle, the scapula and the humerus. These three bones make up the shoulder girdle. The guide of the humerus is called the glenoid fossa and the cavity of the scapula is called the glenoid cavity, these two sound together to form the glenohumeral joint. The glenoid fossa is lar ge when compared to the small appear celes! tial orbit of the glenoid cavity, making the joint shallow and not planning a snug fit. Although this allows a wide range of movement, it also makes it sensitised to injury such as dislocation. To make the joint structure more stable, it is held together by three components; ligaments, cartilage and a group of four muscles called the rotator cuff muscles. Ligaments attach bone to bone...If you motivation to get a full essay, order it on our website: OrderEssay.net
