Abstract

Knowledge of retroperitoneal anatomy is particularly important in order to facilitate the surgical procedure and reduce the number of complications. The objective of this video is to demonstrate pelvic neuroanatomical structures and their relationships in the pelvic side wall and the presacral space in a laparoscopic cadaveric dissection. Case report (anatomical study). Medical Training Center (AdventHealth Nicholson Center, Orlando, FL, USA). The authors have no conflicts of interest to declare. The dissection started by the mobilization of the iliac vessels from the pelvic sidewall in order to identify the obturator nerve. The peritoneum of the ovarian fossa was opened, and the ureter was dissected up to the level of the uterine artery. The hypogastric nerve was identified. The close relationship between the ovarian fossa and the obturator nerve could be demonstrated. The deep dissection of the obturator fossa allowed for the identification of the lumbosacral trunk, S1, sciatic nerve, S2, S3, S4, and splanchnic nerves. Then, the ischial spine and the sacrospinous ligament were identified. The pudendal nerve and vessels could be observed passing below the sacrospinous ligament, entering the pudendal canal (Alcock's canal). The...Continue Reading

Barrel cortex

Here is the latest research on barrel cortex, a region of somatosensory and motor corticies in the brain, which are used by animals that rely on whiskers for world exploration.
