|
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
|
|

|
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. |
|

|
|
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
|

and on the right side, to the right renal vein or directly to IVC |
|
NN of adrenal gland
