Caudal mesenteric plexus calves - anatomical studies.

Abstract

Our study aims to elucidate some aspects concerning the vegetative inervation of calf organs situated on the terminal area of the abdominal cavi ty. Research concerning the lumbo-pelvine area were many times performed (Cavine, Habel, Patea), but data are not clear. Fifteen cadavers from 11 fetuses and 4 new - born calves were dissected, observing caudal mesenteric plexus and its connections with both lumbar sympathetic trunks, and pelvic plexus. Caudal mesenteric plexus is centered on one (40% o f cases) or many caudal mesenteric ganglions disposed in garland shape (60% of cases). The abun dance of the tissue around ganglionic mass increa ses with animals' ageing. Hipogastric nerve receives on its tract one or two splanchnic sacral nerves S1 - S2. MATERIAL AND METHOD Fifteen dissections on cadavers from 11 fetuses an d 2 new - born calves were performed. Nervous groups were observed using direct dissection, up to the limit of loop visibility. In order to facilitate the differentiat ion of vegetative groups of vascular groups acetate 10% was dispersed on dissection area.
