In the human arm, the humeral trochlea is the medial portion of the articular surface of the elbow joint which articulates with the trochlear notch on the ulna in the forearm. In humans and other apes, it is trochleariform (or trochleiform), as opposed to cylindrical in most monkeys and conical in some prosimians. [1] .

Trochlea (Latin for pulley) is a term in anatomy. It refers to a grooved structure reminiscent of a pulley's wheel. Most commonly, trochleae bear the articular surface of saddle and other joints: It also can refer to structures which serve as a guide for muscles:

The capitulum laterally articulates with the radius; the trochlea, a spool-shaped surface, articulates with the ulna. The two depressions—the olecranon fossa, behind and above the trochlea, and the coronoid fossa,…

The trochlea is a saddle-shaped anatomical feature of the humerus. It lies in the middle of the distal end and mates with the trochlear notch of the ulna. The surface of both the trochlea and trochlear notch are covered by articular cartilage, which provides a tough, smooth surface for the joint, one of two in the elbow.

The medial portion of the articular surface of distal humerus is named the trochlea, and presents a deep depression between two well-marked borders; it is convex from before backward, concave from side to side, and occupies the anterior, lower, and posterior parts of the extremity.

2020年12月13日 · Trochlea of Humerus. The structure indicated is the trochlea of the humerus. The distal end of the humerus consists of several features: Condyle, consisting of the capitulum and trochlea; Medial and lateral epicondyles; Medial and lateral supracondylar ridges; Radial fossa, coronoid fossa, olecranon fossa
