ARTICULATIO HUMERI Meaning and
Definition
-
Articulatio humeri, commonly known as the shoulder joint, is a highly mobile synovial joint that connects the upper extremity of the humerus bone with the scapula bone. It is a complex joint responsible for providing a wide range of motion to the arm.
The articulatio humeri is classified as a ball-and-socket joint due to its structure. The rounded, ball-like head of the humerus bone fits into the shallow, cup-like cavity called the glenoid fossa of the scapula bone. This arrangement allows for multi-axial movement in various directions, including flexion, extension, abduction, adduction, and circumduction.
The stability of the articulatio humeri is aided by a group of fibrous ligaments that maintain the position and alignment of the bones while preventing excessive movement. These ligaments include the coracohumeral ligament, the glenohumeral ligaments, and the transverse humeral ligament.
The articulatio humeri is surrounded by a joint capsule, which is lined with synovial membrane that secretes synovial fluid. This fluid lubricates the joint, reducing friction between the bones during movement. The presence of numerous bursae (small fluid-filled sacs) also helps to cushion and protect the articulating surfaces.
The functionality and flexibility of the articulatio humeri are essential for performing activities of daily living, sports, and other physical movements. However, its inherent mobility also makes it prone to injuries, such as dislocations, rotator cuff tears, and inflammatory conditions like arthritis.
