  • Front
  • Back
superficial abdominal muscles NN
all inntervated by 6 lower intercostal nerves and L1
NN of cremaster muscle
genital branch of the genitofemoral nerve
NN of Mesentery
parietal layer by somatic nerves; visceral layer by autonomic nerves
Forgut NN
celiac trunk
Midgut NN
sup mesenteric artery
Hindgut NN
inf mesenteric artery
Esophagus NN
sympathetic and parasympathetic (vagus
Blood supply of upper part of Esophagus
inf. thyroid artery
Blood supply of middle part of Esophagus
thoracic aorta and bronchial arteries
Blood supply of lower part of Esophagus
L gastric artery (from celiac A) and inf phrenic artery (from ab aorta)
Blood supply and venous drainage of stomach: arteries
Left gastric artery , Celiac artery, Right gastric a, common hepatic a, Short gastric aa and the left gastro--epiploic artery splenic artery, Right gastroepiploic a gastro-
duodenal artery common hepatic artery.
Parasympathetic (vagus) NN of stomach
are ant & post vagus trunks, giving the ant & post gastric (Latarget) nerves
Sympathetic NN of stomach
Mostly coming from splanchnic nerves (also from upper lumbar) which synapse in the Celiac ganglion.
Postganglionic fibers innervate stomach; inhibit peristalsis & gastric secretion & cause pyloric contraction; also convey pain.
NN of digestive system
supplied by 2 different plexuses: submucosal
plexus of Meissner (1) and Myenteric plexus of Auerbach
Blood supply of small intestines: arteries
various branches of sup mesenteric A; jejunal and ileal arteries.
Blood supply of small intestines: veins
blood from small intestine carried by sup mesenteric vein into portal vein and to liver.
NN of small intestines: sympathetic
splanchnic nerves via sup mesenteric & intermesenteric ganglia; Inhibition of peristalsis & contraction of ileocecal sphincter & vasoconstriction of vessels.
NN of small intestines: parasympathetic
Vagus nerve, causing peristalsis and glandular secretion.
Blood supply of R and L colon
mesenteric arteries
NN of ascending colon
lesser splanchnic n
Blood supply of rectum and anus: Arteries
Superior rectal artery, final branch of inf mesenteric A supplies sup part of rectum; Middle rectal A. coming from int iliac A supplies middle inf rectal A., branch of int pudendal A, also coming from int Iliac A, supplies lower part of rectum
Blood supply of rectum and anus: Veins
sup rectal V drains into inf mesenteric V & then into portal V; middle & inf rectal veins drain into int iliac vein. Portocaval anastomosis
NN of rectum and anal canal: sympathetic
from lumbar part of the trunk through the sup. hypogastric
plexus.
NN of rectum and anal canal: parasympathetic
by S2, S3 & S4 nerves (pelvic splanchnic nerves); run into inf
hypogastric plexus; sensitive only to stretching.
Blood supply on pancreas
By sup & inf pancreaticoduodenal arteries & arteries from the splenic artery
Venous drainage of pancreas
corresponding veins and finally to the portal vein.
NN of pancreas
Sympathetic and parasympathetic (vagus)
Blood supply of the spleen
Splenic artery coming from the celiac trunk
NN of spleen
by sympathetic and parasympathetic (branches of vagus) nerves.
Blood supply of the kidney
Renal arteries are direct branches of abdominal aorta; give inf suprarenal arteries; receive blood from iliac A originally in ascendance, get blood from lower parts of abdominal aorta & upper part of abdominal aorta
Venous drainage of kidney
through renal veins; drain into IVC; L renal vein is longer than R; L gonaldal vein drains into the L renal vein; R gonadal vein
drains into IVC
Blood supply of adrenal gland
Sup suprarenal arteries from inf phrenic artery on both sides
middle suprarenal arteries arise directly from the abdominal aorta.
inf suprarenal arteries arise from renal arteries on both sides
Venous drainage of adrenal gland
usually by one vein. On the left side to the left renal vein
and on the right side, to the right renal vein or directly to IVC
NN of adrenal gland
sympathetic and parasympathetic
