Variations In Source And Pattern Of Arterial Supply To The Trigeminal Ganglion With Clinical Relevance, William S. Srinivasan

Theses & Dissertations

The trigeminal ganglion (TG) is known to receive its arterial supply from branches of the internal carotid artery (ICA), middle meningeal artery (MMA), accessory meningeal artery (AMA), or superior cerebellar artery (SCA). Existing information about the prevalence and patterns of blood supply to the TG is limited despite their high clinical relevance to basicranial surgeries. The objective of this study is to investigate the source and pattern of arterial supply to TG and discuss their clinical relevance. Left and right TG were examined on 75 embalmed human cadavers from an ethically approved anatomical donor program. A literature review was conducted, …

Cystic Duct Morphology And Heister Valves: A Cadaveric Study, Cierra R. Goerish

Theses & Dissertations

Continued occurrence of cholelithiasis, gallstones, commonly results in cholecystectomy, removal of the gallbladder. Having a comprehensive anatomical, histological, and physiological knowledge of the biliary apparatus is imperative in clinical medicine today. Additionally, the functionality of cystic duct (CD) Heister valves (HV) has been speculatory since being reported in 1732. This study summarizes the morphology, orientation, and variability of the gross biliary system and provides data to help justify HV functionality.

Cadaveric dissection was utilized for gross observation and analysis of the biliary system. The angulation of the CD was found primarily as an acute angle; however, obtuse angulation could be …
