Q

Arteries of stomach

A 
All off celiac trunk:
R & L gastric- lesser curvature
R & L Gastroepiploic (gastroomental)- greater curvature
Posterior gastric- body
Short gastric- fundus
17
Q

Veins of stomach

A 
Into hepatic portal vein
R& L gastric vein
R & L gastroepiplocic
Posterior gastric
Short gastric
18
Q

Innervation of stomach

A

Intrinsic
Parasymathetic
Sympathetic

19
Q

Parasympathetics of stomach

A

Vagal trunk- in brainstem
Terminal ganglia outside wall of stomach- synapse
speed up peristalsis

20
Q

Sympathetics of stomach

A

1st neuron- Intermediolateral cell columns-> ventral root-> white rams communicants, through sympathetic chain into greater or lesser splachnic nerves.
2nd neuron- Synapase at celiac ganglion- follows arteries

21
Q

Afferents of stomach- vagus nerve & dorsal root ganglion

A

1 from vagus, end as stretch receptors in stomach

Primary from dorsal root ganglia of thorax- detects inflammation

22
Q

Function of Sympathetic NS to stomach

A

Stops peristalsis

Sympathetic tone to keep sphincters closed

23
Q

Duodenum function

A

Neutralize stomach acid
Add pancreatic juices
Begin absorption of nutrients

24
Q

2nd part of duodenum

A

Immobile
Retroperitoneal
Entrance for bile and pancreatic ducts
Superior

25
Q

Blood supply to duodenum

A
  • Superior mesenteric artery
  • Anterior & posteror superior pancreaticoduodenal arteries
  • Anterior & posterior inferior pancreaticoduodenal artery
26
Q

4th part of duodenum

A

Suspensory muscle of duodenum- facilitates movement of food

Attached to diaphragm

27
Q

Sympathetic Nerves to duodenum

A

Celiac ganglion & superior mesenteric ganglion

28
Q

Jejunum & ileum function

A

nutrient absorption

29
Q

Arteries to jejunum and ilium

A

Superior mesenteric artery-> arteria recta- penetrate

30
Q

Sympathetic nerves to jejunum & ilium

A

Superior mesenteric ganglion

31
Q

Enteric nervous system

A 
microscopic- control peristalsis
Pacemaker neurons
Integrative neurons
afferent neurons
efferent neurons
32
Q

Gastric Ulcer

A

H pylori infectionor NSAIDs
Sx- Dull abdominal pain after eaten, weight loss, nausea, nocturnal abdominal pain. Referred pain to left shoulder
Break down of mucosal lining of stomach and duodenum.

33
Q

Biliary Obstruction

A

Sx- jaundice, RUQ tenderness, tender liver edge palpable, positive murphy sign.
Blockage of biliary tree by gallstone

34
Q

Appendicitis

A

Blockage of lumen allows accumulation of bacteria.

Vague periumbilical pain-> shifts to Mcburney point, rebound tenderness, N/V. diarrhea

35
Q

Ureterlithiasis

A

Flank pain, chills, hematuria, dysuria, freq and urgent urination
Due to stone from kidney in ureter

36
Q

Ruptured spleen

A

LUQ pain, hemoperitomeum, due to blunt abdominal trauma, rebound tenderness
