Ulna
Definition:

(n.) An ell; also, a yard.
Example Sentences:

(3) The length of ulna resected was not related to the outcome of the operation.
(4) The brace extended from the proximal radius and ulna to the level of the radial styloid and allowed a full range of movement at the radiocarpal joint.
(5) A report is given on a small-for-date male infant showing the following symptoms: bilateral aplasia of humerus, radius, and ulna, shortened femora, bilateral cleft lip and cleft palate, stigmata of dysmorphism, and notably; simple helix formation of the ear, simian crease, clinodactylia, bilateral clubfoot deformity, hypospadia, thrombocytopenia, micrognathia, and contractures in the knee joints.
