anatomy pearls Flashcards
drainage of left testicular vein
left renal vein
drainage of right testicular vein
IVC
gerota’s fascia
surrounds kidney
prominent collateral circulations seen in portal htn
esophageal varices, hemorrhoids, patent umbilical vein, retroperitoneal vein via lumbar tributaries
retroperitoneal GI parts
most of the duodenum, ascending colon, descending colon, pancreas
gubernaculum
embryologic structure that adheres the testes to the scrotum - helps manipulate testes during indirect hernia repair
artery eroded by duodenal ulcers
gastroduodenal ulcurs
lymph nodes between pec major and minor
rotter’s nodes
is the left vagus nerve anterior or posterior
anterior; remember that the esophagus rotates during development
morrison’s pouch
hepatorenal recess; the most posterior cavity w/in peritoneal cavity
foregut
mouth to ampulla of vater
midgut
ampulla of vater to distal third of transverse colon
hindgut
distal third of transverse colon to anus
where are the blood vessels on a rib
vein, artery, nerve are underneath the rib; thoracintesis needles go above
order of femoral vessels
NAVEL (lateral to medial)
hesselbach’s triangle
area bordered by inguinal ligament, epigastric bessels, and lateral border of the rectus sheath
nerve located on top of spermatic cord
ileoinguinal nerve
calot’s triangle
area bordered by cystic duct, common hepatic duct, cystic artery
calot’s node
lymph node found in calot’s triangle
what separates the right and left lobes of the liver
cantle’s line - a line drawn from the IVC to just left of the gallbladder fossa
gastrinoma triangle
triangle where >90% of gastrinomas are located, bordered by junction of 2nd and 3rd portions of duodenum, cystic duct, and pancreatic neck
which artery is responsible for anterior spinal syndrome
artery of adamkiewicz
mcburney’s point
one third of the distance from the anterior superior iliac spine to the umbilicus (estimate the position of the appendix)
how can you find the appendix after you find the cecum
trace the taeniae back as they converge on the origin of the appendix
where is the space of retzius
preperitoneal space anterior to the bladder
what are the white lines of toldt
lateral peritoneal reflections of the ascending and descending colon
what is the strongest layer of the small bowel
submucosa (not the serosa; think SUbmucosa, SUperior)
which parts of the GI tract do not have a serosa
esophagus, middle and sital rectum
what is the vein that overlies the pylorus
vein of mayo
what is the pouch of douglas
pouch between the rectum and bladder or uterus
what does the thoracic duct empty into
left subclavian vein, left internal jugular vein junction
what is the coronary vein
left gastric vein
what is the hypogastric artery
internal iliac artery
which is longer, the left or right renal vein
left
what are the layers of the adbominal wall
1 skin, fat 2 scarpa’s fascia 3 external oblique 4 internal obligue 5 transversus abdominis 6 transversalis fascia 7 preperitoneal fat 8 peritoneum
what are the plicae circulares
plicae = fold, circulars = circular. the circular folds of mucosa of the small bowel
what is another name for the plicae circulares
valvulae conniventes
what are the major structural differences between the jejenum and the ileum
jejunum - long vasa rectae, large plicae, thicker walls. ileum - shorter vasa rectae, smaller plicae, thinner walls (think ileum - inferior inferior inferior)
what are the major anatomic differences between the colon and the small bowel
colon has taeniae coli, haustra, and appendices epiploicae (fat appendages), whereas the small intestine is smooth
how far up does the diaphragm extend
to the nipples in men (4th intercostal space, thus the abdomen extends to the level of the nipples)
what dermatome is at the umbilicus
T10
what are the major layers of an artery
adventitia, media, intima
