  2. Trochlea of humerus - Wikipedia

    en.wikipedia.org/wiki/Trochlea_of_humerus

    The spiralling nature of the trochlear groove results in the varying transverse axes of the elbow joint. [3] Most frequently, the groove is vertical on the anterior side but runs down laterally on the posterior side. During elbow flexion, the vertical anterior part of the trochlea keeps the upper arm and forearm aligned (when viewed in front).

    The intercondylar fossa of femur and/or the patellar surface may also be referred to as the patellar groove, patellar sulcus, patellofemoral groove, femoropatellar groove, femoral groove, femoral sulcus, trochlear groove of femur, trochlear sulcus of femur, trochlear surface of femur, or trochlea of femur.

    en.wikipedia.org/wiki/Humerus

    The humerus (/ ˈ h juː m ər ə s /; pl.: humeri) is a long bone in the arm that runs from the shoulder to the elbow.It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections.

  5. Medial patellofemoral ligament - Wikipedia

    en.wikipedia.org/wiki/Medial_patellofemoral_ligament

    The patella rests in the trochlear, which is found in the distal part of the femur. The patella can dislocate from the groove because of trauma or an unnatural twisting of the knee. [5] When dislocated, the soft tissue layer that the patella rests in is damaged; the patella is forced out of its groove and back into place.

  6. Trochlear notch - Wikipedia

    en.wikipedia.org/wiki/Trochlear_notch

    The trochlear notch (/ ˈ t r ɒ k l ɪər /), [1] also known as semilunar notch and greater sigmoid cavity, is a large depression in the upper extremity of the ulna that fits the trochlea of the humerus (the bone directly above the ulna in the arm) as part of the elbow joint. It is formed by the olecranon and the coronoid process.

  7. Stifle joint - Wikipedia

    It is located cranially to the joint and sits in the trochlear groove of the femur. It guides the patellar ligament of the quadriceps over the knee joint to its point of insertion on the tibia. Caudal to the joint, in the dog for example, are the two fabellae , which lie in the two tendons of origin of gastrocnemius .

  9. Capitulum of the humerus - Wikipedia

    en.wikipedia.org/wiki/Capitulum_of_the_humerus

    In non-avian archosaurs, including crocodiles, the capitellum and the trochlea are no longer bordered by distinct etc.- and entepicondyles respectively, and the distal humerus consists two gently expanded condyles, one lateral and one medial, separated by a shallow groove and a supinator process. Romer (1976) homologizes the capitellum in ...
