Surface Anatomy Of The Shoulder Wikiradiography Physical Therapy 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. The surface of the humeral head is three to four times larger than the surface of glenoid fossa, meaning that only a third of the humeral head is ever in contact with the fossa and labrum. this incongruent bony anatomy allows for the wide range of movement available at the shoulder joint but is also the reason for the lack of joint stability.
Shoulder Musculoskeletal Key Learn about the bones, joints, muscles, and ligaments of the shoulder, the most mobile part of the body. see diagrams and explanations of the shoulder anatomy and common injuries. The shoulder demonstrates a unique functional balance between mobility and stability through active forces, known as dynamic stabilisation, which is the reliance on active forces or dynamic muscular control rather than passive stabilisation through passive forces such as articular surface configuration, capsule, or ligaments. thus within the. The shoulder joint is a ball and socket joint (spheroidal joint). this is a joint where a rounded bone moves inside the curved surface of another bone. you can mimic this joint by making your right hand into a fist and placing your fist into the palm of your left hand. cup the fingers of your left hand over your right fist. The three bones of the shoulder are the: humerus (arm bone) scapula (shoulder blade) clavicle (collarbone) the scapula has one part that forms a socket for the head of the humerus, called the glenoid fossa. the glenoid fossa is covered with a smooth cartilage called the labrum. the rounded top of the arm bone (head of the humerus) contacts the.

The shoulder is a complex anatomical structure consisting of four joints. [1] movements at the shoulder enable us to move and position our arm and hand in space. the muscles of the shoulder provide a stable base for these upper extremity movements. the dynamic relationship between the shoulder muscles, ligaments and bony articulations allows. The shoulder girdle functions as the anchor that attaches the upper limbs to the axial skeleton. additionally, the shoulder girdle allows for a large range of motion, mainly in the highly mobile scapulothoracic joint. this article will discuss the anatomy and functions of the shoulder girdle. key facts about the shoulder girdle.
