The humerus (upper arm bone) is closer to the body than the ulna and the radius (lower arm bones) and so it is proximal.
See link below: Table #3
The proximal attachment of the anconeus muscle is the lateral epicondyle of the humerus, while the distal attachment is the olecranon process of the ulna. The anconeus muscle plays a role in assisting the triceps brachii muscle in extending the forearm at the elbow joint.
The ulna.
No, the patella is not proximal to the ulna. The patella is the kneecap, and is on the lower extremity. The ulna is the smaller of the forearm bones. Since the structures are on different limbs, you can't use the directionals proximal and distal. However, the patella is inferior and medial to the ulna.
Radius and Ulna all in the arm
At the distal end: the carpels in the hand at the head of the ulna and the radius at the ulna notch of radius. At the proximal end: the trochlea of the humerus at the trochlear notch and coronoid process of the ulna and the head of the radius at the radial notch of the ulna.
Humerus
The ulna is a bone of the arm, and the tibia is a bone of the leg. They have no articulations.
Elbow Joint with the shoulder joint and wrist joint as stabilizing joints
Phalanges are distal to the the ulna bone. By the way the ulna bone does not participate in formation of the wrist joint.
No. The wrist is DISTAL to the elbow. The radius and the ulna ( your forearm ) are what separates the elbow joint from the carpals, and the metacarpals, which is your wrist.
The ulna is proximal to the carpal bones. The carpal bones are distal to the ulna.
The radius bone in the forearm is distal to the cubitus (ulna) and proximal to the carpus (wrist bones).
