Glenoid fossa

The glenoid fossae are flattened depressions located at the edges of the articular surfaces that provide precise alignment of the bones in the joint. The articular surfaces of bones are covered with hyaline (articular) cartilage, which plays an important role in providing lubrication and shock absorption during joint movement. The joint consists of an articular capsule and three main elements - the superior (external) and inferior (internal) inversions, separated by a sedentary patellofemoral ligamentous apparatus “McShafferd's cross”, as well as the condyles and epicondyles of the femur. As a result of the sliding that accompanies the movement of bones in the articular joint, there is a need to lubricate the contact surfaces of the cartilages. For this purpose, the fluid of a semi-liquid special ratio, called synovial fluid, includes proteins, glycoproteins and mucopolysaccharides, which facilitate the friction of bones against each other and reduce the level of joint injury.
