posterior branches

pos·te·ri·or branch·es

branches directed dorsally or backward. Terminologia Anatomica lists a posterior branch (ramus posterior) for the following: 1) great auricular nerve (nervi auricularis magni [TA]); 2) inferior pancreatico-duodenal artery (arteriae pancreaticoduodenalis inferioris [TA]); 3) medial cutaneous nerve of forearm (nervi cutanei antebrachii medialis [TA]); 4) obturator artery (arteriae obturatoriae [TA]; 5) obturator nerve (nervi obturatorii [TA]); 6) posteromedial central arteries (arteriae centrales posteromediales [TA]); 7) right branch of portal vein (rami dextri venae portae hepatis [TA]); 8) right hepatic duct (ductus hepatici dextri [TA]); 9) right superior pulmonary vein (venae pulmonitis dextri superioris [TA]); and 10) ulnar recurrent artery (arteriae recurrentis ulnaris [TA]).

The AIB gives off right and left anterior ventricular, anterior septal and corresponding posterior branches (Standring et al.
The bifurcation of the axillary nerve into anterior and posterior branches may occur within the quadrilateral space or within the deltoid muscle.
Posterior branches of the facial suture transverse, curved outwards immediately behind the palpebral lobes.
1,2] The femoral nerve block is performed on the main stem of the nerve, inferior to the inguinal ligament, before it divides into anterior and posterior branches.
5) The great auricular nerve exits the cervical plexus along the posterior margin of the sternocleidomastoid muscle, and it extends anteriorly along the lateral aspect of the sternocleidomastoid muscle and the parotid gland superiorly, where it further divides into anterior and posterior branches.
INTRODUCTION: The abdominal aorta has anterior, lateral and posterior branches as it passes through the abdominal cavity.
Cerebral artery MR angiography, bilateral carotis arteries, anterior cerebral artery, pericallosal artery and mid cerebral artery, Willis Polygon arterial structures, basilar artery, and arteria cerebri posterior branches were normal; no aneurysm, malformation or displacement were detected; venous MR angiography revealed a slightly weakened right transverse sinus calibration (variation) and normal sagittal sinus, straight sinus, left transverse and sigmoid sinus alignments and calibrations.
In the first instance, this occurred at the obturator foramen on emergence into the thigh, where the posterior division is framed by the branches of the obturator artery and vein, and is crossed by the anastomosing vein between the anterior and posterior branches of the obturator vein.
1 mm long; CuA + CuPa with a main anterior stem emitting posterior branches, themselves branched, totalling 13 main branches (as preserved), some of these with apical forks; area between CuA + CuPa and CuPb broadly filled with crossveins; as preserved, CuPb simple and weak; AA1 branched and reticulated with the anterior branch of AA2; AA2 branched; crossvenation loose; right forewing: CuA + CuPa with at least 12 main branches; area between CuA + CuPa and CuPb filled with crossveins.
In the supraclavicular fossa the superior, middle and inferior primary trunks divide into their anterior and posterior branches.
The regular artery gave off the thoracoacromial and two posterior branches from its second part, the anterior and posterior humeral circumflex arteries from its third part, and then continued as the brachial artery with all the usual branches except the profunda brachii on the right side.
The author hypothesized that the use of this procedure to remove a benign pleomorphic adenoma might result in even less morbidity (transient or permanent facial nerve dysfunction, facial contour disfigurement, Frey's syndrome, and hypoesthesia) without increasing the risk of recurrence if only a 1-cm margin of normal parotid parenchyma was removed and if the posterior branches of the great auricular nerve were preserved.
