medial branches

me·di·al branch·es

[TA]
branches directed toward the midline, to the middle. Terminologia Anatomica lists medial branches (ramus medialis/rami mediales) of the following: 1) pontine arteries (rami mediales arteriae pontis [TA]); 2) artery of tuber cinereum (ramus medialis arteriae tuberis cinerei [TA]); 3) posterior rami of cervical/thoracic/lumbar/sacral/coccygeal spinal nerves (rami medialis ramorum posteriorum nervorum cervicalium/thoracicalium/lumbalium/sacralium/coccygeum [TA}); 4) umbilical part of left branch of portal vein (rami mediales portis umbilici rami sinistri venae portae hepatis [TA]); 5) left hepatic duct (ramus medialis ductus hepatici sinistri [TA]); 6) middle lobar artery (of right lung) (ramus medialis arteriae lobaris mediae (pulmonis dextrum) [TA]); 7) superior cerebellar artery (ramus medialis arteriae superior cerebelli [TA]); 8) supraorbital nerve (ramus medialis nervi supraorbitalis [TA]).

(2017), reported 20-35 % of these cases]; it emerges from the right portal branch in 79 %; the branch for segment V, after deepening 2 cm in its segmental parenchyma, gives anterior, lateral, posterior and medial branches which encompass the parenchyma between the right portal fissure (A05.8.01.036) and the main portal fissure (A05.8.01.035) from the inferior borderof the liver (A05.8.01.024) to the inferior vena cava (A12.3.09.001).
When conservative treatment fails, interventional pain management methods, including injection of local anesthetics and corticosteroid at the location of great occipital nerve (GON), intraarticular/medial branch corticosteroid injection (C2-3, C3-4 zygapophysial joints, medial branches of the C3 and C4 dorsal rami), radiofrequency ablation (RFA), occipital nerve stimulation, epidural steroid injections, and surgical treatment are other options for the treatment of CH (5,6).
The medial branches of the lower thoracic sympathetic ganglia; the greater and lesser splanchnic nerves, enter the abdomen by piercing the diaphragmatic crura and finally relay in the celiac ganglia and contribute in the formation of celiac plexus.
Each facet is innervated by the medial branches of the posterior rami of the spinal nerves above and below the joint.
However, the medial branches of the dorsal rami are mixed nerves that also independently and segmentally innervate the lumbar multifidus muscles [30].
The lateral branches arise dorsally to the medial branches of the testicles in 56.25%, ventrally in 12.5% and at the same level in 31.25% of the cases studied.
Tracheo-oesophageal branches and cardiac branches were given as medial branches. Vascular branches were seen forming plexus over inferior thyroid artery in all the 22 cases.
The branch V (yellow) rises above giving anterior, lateral, posterior and medial branches. Segment V posterior branches are distributed among the portal vein, the intermediate and right hepatic veins above segment I (light blue).
Our hypothesis was that subclinical Sacroiliac joint pain would become more apparent and is hence clinically diagnosed more often in the subsequent follow-up visits after an intervention such as radiofrequency rhizotomies of the medial branches of lower lumbar dorsal rami has been performed to address the pain from the lumbar facet joints.
(15) Anterior interosseous nerve syndrome (AINS) would be of complete type when the entire of AIN passes posterior underneath the AHFPL belly causing weakness of all the three muscles supplied by it and incomplete type of AINS is likely to occur when only the medial branches of AIN to the FDP which passes beneath the muscle belly is compressed.
It enters the carpal tunnel deep to the flexor retinaculum and beyond its distal border divides into lateral and medial branches. The lateral branch supplies the three thenar muscles and subdivides into proper palmar digital nerves supplying the lateral 1 and % fingers and the 1st lumbrical.
