Ulnas [noun]

The ulna must then be cleared, and the triceps divided at its insertion.

Ulna, from the top of the shoulder or arme-hole, to the top of the middle finger.

The ends of the secondaries must not be separated from the bone of the forearm, or the ulna.

Its radius and ulna are separate bones, not fused as they are normally.

The fore-arm or antibrachium consists of two bones, the radius and ulna.

The ulna (fig. 57, 3) is longer, stouter, and slightly curved.

The radius and ulna can be rotated on one another to a considerable extent.

The radius and ulna are well developed, but are not capable of much rotation.

The development of the fibula in general corresponds to that of the ulna.

The radius and ulna are not ankylosed, but are incapable of any rotatory movement.
