Vasculature, Innervation & Lymphatices (Gross Anatomy 2)
Question | Answer |
---|---|
Celiac Trunk | T12; L.gastric A., Splenic A., Common Hepatic A. |
Superior mesenteric | L1; Jejunal & ilial branches, Iliocolic A., R. colic A., Middle colic A. |
Inferior mesenteric | L3; L.colici A., Sigmoid A., Superior rectal A. |
Celiac trunk supplies | Esophagus, stomach, spleen, liver, gallbladder, part of duodenum, part of pancreas |
SMA supplies | uncinate process of pancrease, Jejunum, Ilium, Cecum & appendix, ascending colon, most transverse colon |
IMA supplies | distal end of transverse colon, descending colon, sigmoid colon, rectum |
Inferior mesenteric v. drains into | splenic v. |
splenic & superior mesenteic vv. join to form | Hepatic portal v. |
L. gastric v. drains directly into | portal vein |
blood from digestive tract & spleen passes through | liver |
All organs receiving blood from celiac trunck get prepanglionic sympathetic innnervation from | greater splanchnic n. (T5-T9) |
All organs receiving blood from superior mesenteric a. get preganglionic sympathetic innervation from | lesser splanchnic n. (T10-T11) |
All organs receiving blood from inferior mesenteric a. get preganglionic sympathetic innervation from | lumbar splanchnic nn. (L1-L2) |
All abdominal organs which receive blood from branches leaving aorta at L2 or higher get parasympathetic innervation from | vagus nn. |
All abdominal & pelvic organs which receive blood from branches leaving aorta at L3 or below get parasympathetic innervation from | pelvic splanchnic nn. (S2-S4) |
