| posterior branch of inferior pancreaticoduodenal artery | <anatomy, artery> The more dorsal of the two branches into which the inferior pancreaticoduodenal artery bifurcates; supplies uncinate process and head of pancreas, as well as the third and fourth parts of the duodenum; anastomoses with the posterior branch of the superior pancreaticuduodenal artery. Synonym: ramus posterior arteriae pancreaticoduodenalis inferioris. (05 Mar 2000) |
| posterior branch of obturator artery | <anatomy, artery> Branch of obturator artery giving rise to acetabular branch and supplying muscles attached to ischium. Synonym: ramus posterior arteriae obturatoriae. (05 Mar 2000) |
| posterior branch of recurrent ulnar artery | <anatomy, artery> Contributes to blood supply of flexor carpi ulnaris and to articular network of elbow. Synonym: ramus posterior arteriae recurrentis ulnaris. (05 Mar 2000) |
| posterior branch of renal artery | <anatomy, artery> Terminal branch of renal artery (with anterior branch) becoming the posterior segmental artery of kidney. Synonym: ramus posterior arteriae renalis. (05 Mar 2000) |
| posterior branch of superior thyroid artery | <anatomy, artery> Branch of superior thyroid artery which descends to supply the apical portion of the ipsilateral lobe of the thyroid, continuing along the posterior border of the gland to anastomose with the inferior thyroid artery. Synonym: ramus posterior arteriae thyroideae superioris. (05 Mar 2000) |
| posterior scrotal branch of internal pudendal artery | <anatomy, artery> Branches of perineal artery supplying skin of posterior scrotal sac. Synonym: rami scrotales posteriores arteriae pudendae internae. (05 Mar 2000) |
| saphenous branch of descending genicular artery | <anatomy, artery> Branch of descending genicular artery supplying skin of the upper part of the medial aspect of the leg; anastomosis: medial inferior genicular artery (articular vascular network of knee).

| pubic branch of inferior epigastric artery | <anatomy, artery> Branch arising from the inferior epigastric artery medial to the deep inguinal ring; runs medial to femoral ring onto posterior pubis; anastomosis, pubic branch of obturator artery. This anastomosis is frequently large, referred to as an "accessory obturator artery." In 20-30%, this anastomosis replaces the obturator artery, as an "aberrant" or "replaced" obturator artery. Synonym: ramus pubicus arteriae epigastricae inferioris. (05 Mar 2000) |
| pubic branch of obturator artery | <anatomy, artery> Branch arising from the obturator artery just prior to its pasage through the obturator canal; the branch passes superiorly on the posterior aspect of the pubis. Anastomosis: with contralateral partner and pubic branche of inferior epigastric artery. See: accessory obturator artery, pubic branch of inferior epigastric artery. Synonym: ramus pubicus arteriae obturatoriae. (05 Mar 2000) |
| stapedial branch of stylomastoid artery | <anatomy, artery> Branch arising either directly from the stylomastoid artery or its branch, the posterior tympanic artery; supplies stapedius muscle. Synonym: ramus stapedius arteriae stylomastoideae. (05 Mar 2000) |
| sternocleidomastoid branch of occipital artery | <anatomy, artery> Branches of occipital artery to sternocleidomastoid muscle. One often hooks around hypoglossal nerve. It may arise as an independent branch of the external carotid, in which case it may be referred to as the sternomastoid artery. Synonym: rami sternocleidomastoidei arteriae occipitalis. (05 Mar 2000) |
| sternocleidomastoid branch of superior thyroid artery | <anatomy, artery> Branch of superior thyroid artery to sternocleidomastoid muscle. Synonym: ramus sternocleidomastoideus arteriae thyroideae superioris. (05 Mar 2000) |
| superficial branch of the medial plantar artery | <anatomy, artery> Gives rise to superficial digital arteries of medial three toes. Synonym: ramus superficialis arteriae plantaris medialis. (05 Mar 2000) |
