  1. ulna love

Definitions

American Heritage® Dictionary of the English Language, Fourth Edition

  1. n. The bone extending from the elbow to the wrist on the side opposite to the thumb in humans.
  2. n. A corresponding bone in the forelimb of other vertebrates.

Century Dictionary and Cyclopedia

  1. 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.
  2. n. In entomology, the stigmatic or marginal vein of the fore wing.
  3. n. A unit of length; a cubit; an ell.
  4. n. In ichthyology, the hypereoracoid.
