Superior to the anterior portion of the trochlea is a small depression, the coronoid fossa, which receives the coronoid process of the ulna during flexion of the forearm. It is directly adjacent to the radial fossa of the humerus.
The coronoid fossa is a smaller hollow that is also located superior to the trochlea, but on the anterior surface. During flexion of the elbow, the coronoid process of the ulna lodges into the coronoid fossa.
The coronoid fossa is the small depression found superior to the trochlea of the humerus. It is the medial of the two fossae located on the anterior aspect of the condyle of the humerus, the other being the radial fossa. It accommodates the coronoid process of ulna during elbow flexion.
The coronoid and radial fossae are two depressions found on the anterior side of the humerus. The olecranon fossa is located on the posterior side of the humerus. It is important for the elbow extension, as the tip of the ulnar olecranon process lodges into it.
The lower (distal) end of your humerus forms the top of your elbow joint. It meets your forearm bones (radius and ulna). It includes the: Supracondylar ridges. Epicondyles. Trochlea. Capitulum. Coronoid, radial and olecranon fossae.
Superior to the trochlea is the coronoid fossa, which receives the coronoid process of the ulna, and above the capitulum is the radial fossa, which receives the head of the radius when the elbow is flexed.
The coronoid fossa is a shallow depression located on the anterior surface of the distal end of the humerus, where it accommodates the coronoid process of the ulna during forearm flexion. It plays a crucial role in elbow joint movement by allowing the arm to bend smoothly.
The coronoid fossa is located superior to the trochlea and accommodates the coronoid process of the ulna and superior to the capitulum on the anterior surface of the condyle, which is the radial fossa which receives with the head of the radius, both upon flexion of the elbow joint.
Depressions on the humerus that accommodate the forearm bones during bending (flexing) and straightening (extending) of the elbow include the coronoid fossa, the radial fossa, and the olecranon fossa.
