Different types of bone markings and features. A condyle is the round prominence at the end of a bone, most often part of a joint – an articulation with another bone. [2] The epicondyle refers to a projection near a condyle, particularly the medial epicondyle of the humerus. [3] These terms derive from Greek. [4] [a]
The radius is named so because the radius (bone) acts like the radius (of a circle). It rotates around the ulna and the far end (where it joins to the bones of the hand), known as the styloid process of the radius, is [clarification needed] the distance from the ulna (center of the circle) to the edge of the radius (the circle). The ulna acts ...
English: The humerus is the (upper) arm bone. It joins with the scapula above at the shoulder joint (or glenohumeral joint) and with the ulna and radius below at the elbow joint. Notice: When the arm is spun so that the thumb point to the outside of the body, meaning the palm of the hand looks forward then it is said the hand is supinated. But ...
Beneath the neck of the radius, on the medial side, is an eminence, the radial tuberosity; its surface is divided into: . a posterior, rough portion, for the insertion of the tendon of the biceps brachii.
The medial epicondyle of the humerus is an epicondyle of the humerus bone of the upper arm in humans. It is larger and more prominent than the lateral epicondyle and is directed slightly more posteriorly in the anatomical position. In birds, where the arm is somewhat rotated compared to other tetrapods, it is called the ventral epicondyle of ...
The ulna forms part of the wrist joint and elbow joints. Specifically, the ulna joins (articulates) with: trochlea of the humerus, at the right side elbow as a hinge joint with semilunar trochlear notch of the ulna. the radius, near the elbow as a pivot joint, this allows the radius to cross over the ulna in pronation.
