Feline arterial corrosion cast specimen. The brachial a. (1) can be seen passing through the supracondylar foramen (2) prior to entering the antebrachium. The brachial a. gives rise to the deep antebrachial a. (3) and then a cranial interosseous a., caudal interosseous a. (4) and ulnar a. (5). Distal to the caudal interosseous branch, the brachial a. is renamed median a. (6). In the distal antebrachium, the median a. gives rise to a large radial a. (7), which is the main source of blood to the manus. In this preparation, the median a. is missing distally; an arrow indicates where the branching occurs and the inset shows the branching pattern in a different specimen.
The feline pattern of antebrachial vessels differs from the canine pattern, including: a supracondylar foramen, lack of a common interosseus a., and a large radial a. (The median n. accompanies the brachial a. through the supracondylar foramen.)
