Gross 2 *Abdominal Viscera* Flashcards
Pain arising in the foregut organs is typically referred where?
Epigastric
Pain arising from the midgut is typically referred where?
Peri-Umbilical
Pain arising from the Hindgut is typically referred where?
Hypogastric / Pubic
Pain can be referred to the shoulder due to the relationship to what?
Relationship of organ to diaphragm
Which organs can refer pain to the posterior body wall/trunk?
Pancreas, kidney, ureter
Kidney and Ureter (Genitourinary) can refer to inguinal region and anterior thigh (Loin to Groin)
What are the branches of the Celiac Trunk?
- Splenic A.
- Left Gastric A.
- Common Hepatic A.
What visceral organs does the Celiac Trunk supply?
- Terminal end of esophagus
- Stomach
- Duodenum
- Spleen
- Liver
- Gallbladder
- Pancreas
Where is the esophagus located?
- Left Upper Quadrant
- The esophagus passes through the diaphragm at the level of T10
- The esophagus terminates at the cardiac orifice of the stomach
What arteries supply the esophagus in the abdominal region?
- Esophageal branch from Left Gastric (Celiac Trunk)
- Left Inferior Phrenic A.
What is the pathway to arrive to the Esophageal B and Left Inferior Phrenic from the aorta?
Abdominal Aorta -> Celiac Trunk -> Left Gastric
-> Esophageal Branch
Abdominal Aorta-> Left Inferior Phrenic A.
What innervates the terminal end of the Esophagus?What effect does the innervation have?
- Parasympathetic
– Esophageal Plexus (From Vagal Trunk)
–Peristalsis
–Secretion of mucus - Sympathetic
– Greater Splanchnic Nerve
–Inhibits peristalsis and constricts blood flow - Visceral Afferent
– Posterior surface of the abdominal part of the esophagus is covered by peritoneum
Where is the stomach located?
Left Upper Quadrant, except the Pylorus (RUQ)
- Lies between the esophagus and duodenum
What are the parts of the stomach?
- Cardia: surrounds the cardiac orifice
- Fundus: (Top part of stomach) Area may be dilated by gas, fluid, or food
- Body: Between fundus and pylorus
- Pylorus: (Bottom part of stomach) Contains the pyloric atrium and canal
What are the arteries that supply the stomach?
Right and Left Gastric -> Lesser Curvature
Right and Left Gastro-omental -> Greater Curvature
Short Gastric -> Fundus of stomach
What is the pathway for the Right and Left Gastric arteries to the stomach from the aorta?
Abdominal Aorta -> Celiac Trunk -> Left Gastric
Abdominal Aorta -> Celiac Trunk -> Common Hepatic
-> Proper Hepatic -> Right Gastric
What is the pathway for the Right and Left Gastro-omental to the stomach from the aorta?
Abdominal Aorta -> Celiac Trunk -> Common Hepatic
-> Gastroduodenal -> Right Gastro-omental
Abdominal Aorta -> Celiac Trunk -> Splenic -> Left Gastro-omental
What is the pathway for the Short Gastric to the stomach from the aorta?
Abdominal Aorta -> Celiac Trunk -> Splenic
-> Short Gastric
What innervates the stomach?
- Parasympathetic
– Anterior and Posterior Vagal - Sympathetic
– Greater Splanchnic Nerves
What is the function of the stomach?
- Chemical and mechanical breakdown of food
- Passage to duodenum
Where is the Duodenum?
- Right Upper Quadrant
- Begins at the Pylorus
- Ends at duodenal jejunal flexure
What are the parts of the Duodenum?
- Superior
- Descending
- Horizontal
- Ascending
*The bile and main pancreatic duct enter the posteriomedial wall of the descending part
What is the function of the Duodenum?
- Absorption of water nutrients
- Mixing bile and pancreatic enzymes
