Century Dictionary and Cyclopedia
- n. The inner one of the two bones of the forearm, between the elbow and the wrist, the other being the radius; the bone which makes a strict hinge-joint at the elbow with the humerus, and about which the radius revolves in pronation and supination, when the ulna reaches to the wrist and these movements are practicable. The ulna is commonly the smaller one of the two bones, especially below, where its end is little more than a pivot for rotation of the wrist, the hand being almost entirely borne upon the end of the radius. In many animals the ulna is reduced by shortening, and in some it appears merely as a process of the radius, ankylosed upon the proximal end of the latter, as in bats, and in hoofed quadrupeds generally. In man, in animals generally which use their fore paws as hands, and in birds it is perfect, and extends the whole length of the forearm. Its proximal end has a large sigmoid cavity for articulation with the humerus, often a lesser sigmoid cavity for the head of the radius, and a prominent process, the olecranon, or head of the ulna, forming the greatest convexity of the back of the elbow. See cuts under carpus, Catarrhina, Elephantinæ, forearm, pinion, Plesiosaurus, and shoulder.

- From Latin ulna ("elbow"). (Wiktionary)
- Latin, elbow, forearm. (American Heritage® Dictionary of the English Language, Fourth Edition)
“Plaque-clogged arteries in the abdomen suggest a red-meat eater; black-encrusted lungs signify long-term nicotine addiction; the faint indentation in the ulna is the scarred evidence of an arm broken in childhood.”
“For four or five days I thought over the history of his injury and the resulting inability to rotate the radius around the ulna -- in other words, to turn his hand over.”
“At the elbow, which is the first angle of the wing, reaching backward when the wing is folded, the humerus articulates in a wisely designed way with two other bones, called the ulna and radius, which together constitute the forearm and extend to the wrist joint.”
“(The ulna is the bone that reaches the wrist on the pinkie side.)”
“The medial and lateral heads originate on the upper-arm bone and attach on the ulna, which is one of the forearm bones.”
“In the Negro, the 'ulna', the longest bone of the fore-arm, is nearly of the same length as the 'os humeri', the latter being from one to two inches longer.”
“The fracture of the ulna is a simple one," said the spokesman, "and will become all right in the ordinary course of nature.”
“A left humerus of which the upper-third is wanting, and which is so much slenderer than the right as apparently to belong to a distinct individual; a left 'ulna', which, though complete, is pathologically deformed, the coronoid process being so much enlarged by bony growth, that flexure of the elbow beyond a right angle must have been impossible; the anterior fossa of the humerus for the reception of the coronoid process being also filled up with a similar bony growth.”
“Moving his right arm above water Alex let out a terrified shriek, his ulna and radius were protruding through his skin, and his arm was dangling as he desperatly tried to keep from drowning.”
“Then, almost immediately, Spooky found the ulna of a very large bird (the bone measures 22 cm. along the mid-line).”
