posterior branches

pos·te·ri·or branch·es

[TA]
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]).
Synonym(s): rami posteriores [TA]

Posterior branches of the facial suture transverse, curved outwards immediately behind the palpebral lobes.
Posterior branches of the facial suture become almost transverse immediately posterior of the palpebral lobe termination, then turn backwards to cross the posterior border at short distance from the posterolateral cephalic margin.
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.
In the supraclavicular fossa the superior, middle and inferior primary trunks divide into their anterior and posterior branches.
Innervation of the deltoid is from the axillary nerve, which arises from the posterior cord of the brachial plexus and passes through the quadrilateral space dividing into anterior and posterior branches.
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.
3) Most great auricular nerves have one or two anterior branches and two posterior branches (a superficial branch and a deep branch).
The author hypothesized that partial superficial parotidectomy with facial nerve dissection and preservation might result in even less morbidity if only a 1-cm margin of normal parotid parenchyma was removed and the posterior branches of the great auricular nerve were preserved.
This group was made up of 15 patients who had undergone the standard partial procedure with a 2-cm margin of normal parotid parenchyma and sacrifice of the great auricular nerve (group A), and a matched group of 15 patients who had undergone the modified version with a 1-cm margin and preservation of the posterior branches of the great auricular nerve (group B).
Although this difference is certainly significant, it does indicate that preservation of the posterior branches of the great auricular nerve does not prevent alterations in sensitivity in all patients.
7%]) experienced a tactile sensory deficit despite preservation of the posterior branches of the great auricular nerve.
The vessel coursed from an inferolateral position to a superomedial location along the left nasal vestibule and septum; it bifurcated on the septum into visible anterior and posterior branches.
