| ramus | A standard medical dictionary contains over 13 pages full of entries to the word ramus. Why? because ramus in latin means a branch and all sorts of anatomic items such as blood vessels and nerves quite naturally have branches. So, for example, medicine is plagued with the likes of the ramus acetabularis arteriae circumflexae femoris medialis which is simply the branch of an artery that goes to the acetabulum (the socket) of the hip joint. (12 Dec 1998) |
| ramus acetabularis | An arterial branch that supplies the acetabulum; two arteries, the obturator and the medial femoral circumflex, have such branches. Synonym: ramus acetabularis, acetabular artery, arteria acetabuli. (05 Mar 2000) |

| ramus anastomoticus | The anastomotic branch, a blood vessel that interconnects two neighboring vessels.
