what is the anatomical name for the joint in the elbow from the trochlear notch of the ulna to the trochlea of humerus?
humeroulnar joint
humeroulnar joint









































the humeroulnar joint (ulnohumeral or trochlear joint), is part of the elbow-joint. it is composed of two bones, the humerus and ulna, and is the junction between the trochlear notch of ulna and the trochlea of humerus. it is classified as a simple hinge-joint, which allows for movements of flexion, extension and circumduction. owing to the obliquity of the trochlea of the humerus, this movement does not take place in the antero-posterior plane of the body of the humerus.
humeroulnar joint
the elbow is a hinge joint with a rotatory component where the trochlea forms the convex, proximal surface which articulates with the concave, distal surface on the ulna, the trochlear notch. while the trochlea together with its associated fossae almost covers a 360° angle, the trochlear notch on the ulna forms a 190° arc and the gap in between allows flexion and extension at the elbow. maximum elbow flexion and extension is made possible because the two fossae accommodates to coronoid and olecranon processes.
