Anat. GIT Anatomy and Imaging-Witwer (Exam 2) Flashcards
Hepatic artery goes toward the liver–> hepatic proper artery goes ?
*INTO the liver
Ligament of teres=
end result of the involution of the umbilical vein, in the falsiform ligament
artery of Adamkiewicz(AKA)
also known as the great anterior radiculomedullaryartery, is a majorarterythat joins the anterior spinalarteryin the lower one-third of the spinal cord
BELOW the yellow line=
below the yellow line is RETROperitoneal
- vast majority of pancreas is retraperitoneal except for the tail
- And above it is INTRAperitoneal (the line is the peritoneum)
- what level are we: the transpyloric line= the pylorus, the duodenal bulb, the celiac artery, both renal arteries go out to the side, and renal veins come in, body of the pancreas at this line. It’s half way b/w sternal notch and pubic symphysis. Or halfway b/w xiphoid and umbilicus.
- the liver:
Retroperitoneal organs: S:suprarenal (adrenal) gland A:aorta/IVC D:duodenum(second and third part) P:pancreas(except tail) U:ureters C:colon(ascendinganddescending) K:kidneys E:(o)esophagus R:rectum
Fascia surrounding the kidney=
gerota’s fascia around the kidney (PROTECTS the kidney from developing pancreatitis!
Transverse duodenum location
b/w the SMA/SMV and Aorta
FEMALE PELVIC ANATOMY:
list the 3 common imaging techniques for female/male Pelvis
US: useful for imaging the ovaries, uterus. Or imaging the prostate
MRI: useful for imaging uterus and cervix, and prostate
CT: images uterus, broad and round ligament, ovaries, Seminal vesicles, and prostate , BUT not as well as an MRI
Round ligament originates:
from the uterus
-Round ligament is analogous to the spermatic duct (goes out inguinal canal)
Ascites=
ASCITES IS ABNORMAL! THE ASCITES SLIDES ARE FOR THE ANATOMIC RELATIONSHIPS ONLY
Pouch of douglas aka
*the rectrouterine pouch) where pus and tumor end up
Ovaries can develop ____
follicular cysts*
Describe the uterus
Flexion of the uterus is NORMAL variation***
- Endometrium is the inside of the uterus (mostly mucous or vascular fluid)
- Myometrium= muscle of the uterus
- cervix is located INSIDE the uterus
- Sacrum, coccyx and bladder located inferiorly
Cancer of the Prostate is MC in the _____ portion
MC in the posterior portion (75%)– most are accessible by the digital rectal exam
BPH occurs in the _____ zone
central zone
The prostate capsule is best seen with which imaging study?
- TZ=
- PZ=
MRI
(prostate capsule containes the TZ and PZ)
- transitional zone
- peripheral zone
- Seminal vesicles come in through the posterior urethra (prostatic urethra)
T-3 prostate cancer=
tumor extends beyond the capsule to the rectal wall
Chest films can be very valuable in the evaluation of :
- abdominal pain.
- Sometimes lung or pleural disease can manifest as abdominal pain.
(This pain can be referred to the shoulders (C3, C4 C5)
Free air secondary to a perforated abdominal viscus will gravitate under the _____
diaphragm in an upright film
FREE AIR on Chest film indicates–>
perforation in abdominal viscus
Morison’s pouch=
subhepatic recess, it’s intraperitoneal and it’s located on the right side behind the liver (=posterior hepatorenal space)
Which peritoneum is located in front of the liver?
Which peritoneum is located behind the liver?
- parietal peritoneum
- Visceral peritoneum
Messentary=
is made up of the peritoneum folding around the bowel (mesentery- is what the bowel is hanging off of)
Free intraperitoneal air can occur 2/2:
-perforated viscus
Pneumoperitoneum:
-Morison’s pouch=
Posterior Hepato-
Renal Space
