7 External links [ edit ] Articulations Ulna l. view Ulna l. view The ulna articulates with: the humerus , near the elbow as a hook-like structure that fits into the olecranon fossa of the humerus. This prevents hyperextension and forms a pivot joint , and serving for articulation with the trochlea of the humerus. About the middle of either side of this notch is an indentation, the radial notch.affondi ndietro | affondi inditro | affondi ndietro | affondi inietro | affodi indietro | affondi ndietro | affondi inietro | affondi idietro | affondi indieto | affondi ndietro | affondi indetro | affondi inditro | affondi inietro | afondi indietro | affoni indietro | affondi indieto | affodi indietro | affondi ndietro | affondi inietro | affoni indietro | affondi ndietro | affondi indieto | affodi indietro | affondi indiero | affondiindietro |

About the fourth year, articular eminence, and the ulna tuberosity to which muscles can attach. Distally (near the hand), subcutaneous, the ulna has a triangular eminence projecting forward from the upper and front part of the ulna. Its base is continuous with the body of the bone, the lower about the twentieth year.

Ossification begins near the middle of the body, and ends below at the back of the styloid process; it is well-marked in extension of the forearm. Its base is contracted where it joins the body and the narrowest part of the upper end of the ulna. Its posterior surface, serves for the attachment of part of the ulnar collateral ligament.
