abuts spleen hilum
intraperitoneal and covered by lienorenal lig.
tail of pancreas
duct of wirsung(main panc. duct)
begins at tail and joins common bile duct to form ampulla of Vater, where it empties into duodenum
santorini duct (acc. pancreatic duct)
opens separately into duodenum
adrenal gland
triangular gland
located in adipose tissue on sup aspect of kidney
develop from mesoderm

adrenal medulla
modified nervous tissue
develops from neuroectoderm
adrenal medulla
NCC diff. into medulary cells
of Adrenal medulla
epe and NE
released by adrenal medulla
same effect as direct symp stimulation but last longer
adrenal medulla
can live without adrenal medulla
because post gang. cells provide same function and will compensate for the loss.
