from superficial to deep
- skin
- campers fascia (fatty)
- Scarpas fascia (membranous)
- trilaminar block
- transversals
- exztraperitoneal fat
- parietal peritoneum
3 parts of small intestine
- duodenum
- jejunum
- ileum
large intestine parts (6)
- cecum
- ascending colon
- transverse colon
- descending colon
- sigmoid colon
- rectum
what quadrant is liver in
UR
spleen and stomach, what quadrant
UL

pain experienced with appendicitis
visceral pain LRQ
referred pain around navel
somatic pain in lower right abdominal wall
rebound tenderness = sign of peritoneal irritation
mcburneys point
R side, 1/3 away from the anterior superior iliac spine to the umbilicus
somatic pain
felt by skin
caused by cutting, tearing, temp, inflammation
SHARP and LOCALIZED
visceral pain
felt by organs
ischemia, distention, prolonged smooth muscle contraction
DULL and DIFFUSE
poorly localized
referred pain
feels like somatic but there is nothing wrong with the somatic structure to cause it
often accompanies visceral
where does nearly all venous blood from the gut drain to the liver
