caudal boundary of abdomen?
cranial boundary of abdomen? |
pelvic inlet
diaphragm |
|
Linea alba
|
-formed by the fusion of the aponeuroses of the abdominal muscles
-separates the left and right rectus abdominis muscles. -median incision through the linea alba is a common surgical approach. |

|
Blood Supply—Abdominal Wall
|
|
|
Peritoneal Cavity
|
space betw. parietal peritoneum and visceral peritoneum, that is, two membranes that separate organs in abdominal cavity from abdom.wall.
Contains intestines, stomach, and liver |
|
3 types of peritoneum
|
|
|
Connecting Peritoneum ?
|
Connecting Peritoneum (just like Connecting Pleura) = BILAYER
Bilayer = avenue for vessels & nerves to reach the organs Mesentery - connect jejunum and ilium to back wall Ligament (fold) Omentum - attaches to greater and lesser curvatures of stomach |
|
greater and lesser omentum
|
folds of connecting peritoneum that hang down either side of stomach.
Lesser omentum is connects top edge of stomach to undersurface of liver. Greater omentum is attached to bottom edge of the stomach, and hangs down in front of the intestines. Its other edge is attached to the transverse colon. |
|
What is more ventral pyloric or fundus?
|
pyloric
|
|
What are two layers of greater omentum?
|
greater and lesser leaves
|
|
Which side of diaphragm can be seen on xrays?
Cranial or Caudal? |
Cranial: Yes because of contrasting air density
Caudal: No, due to water density |
|
What is ascites? What causes it?
|
Fluid in the abdomen, caused by right heart failure
|
|
What vessels supply the fundus of the stomach?
What supplies these vessels? |
short gastric aa from splenic a
|
|
what are the 3 branches of the celiac artery?
|
hepatic, splenic and left gastric
|
|
What do the celiac, cranial and caudal mesenteric aa supply?
|
viscera drained by portal vein
|
|
Name 3 main unpaired branches of abdominal aorta?
|
1. Celiac a.
2. cranial mesenteric a. 3. caudal mesenteric a. |
|
What are the primary abd organs not drained by the portal v? why?
|
kidneys, adrenal glands, gonads, liver; not drained b/c hormones would be destroyed by the liver
|
|
What gland is part of the sympathetic ANS?
|
adrenal glands (medulla)
|
|
laparotomy
|
surgical procedure involving an incision through abdominal wall to gain access into abdominal cavity. It is also known as coeliotomy. e.g.exploratory laparotomy
|
|
What structure of the renal pelvis shows up in contrast studies of the kidney that can give clues to problems?
|
pelvic recesses
|
|
What is inflammation of the kidney and its pelvis?
|
pyelonephritis
|
|
What is an incision in to a kidney?
|
nephrotomy
|
|
What is the removal of a kidney? what should be checked first?
|
nephrectomy; check for another kidney before removal of the 1
|
|
How do u visualize the kidneys during a laparotomy?
|
pull descending colon and its mesocolon or descending duodenum and its mesoduodenum medially and look in abd gutter for left and right kidneys
(basically sounds like you are lifting edging of gut up to visualize what's beneath) |
|
Where are the collateral ganglia of the sympathetic division located?
|
near branches of abd aorta
|
|
Describe kidney location in relation to peritoneum
|
“retroperitoneal”
in position (pressed against abdominal wall, behind parietal peritoneum) |
|
The descending duodenum is on what side of the abdomen?
|
Right
|
|
List the parts of the small and large intestine?
|
* Sm: duodenum, jejunum, ileum
* Lg: cecum colon (ascending, transverse and descending) * Rectum and anal canal |
|
On what side is the cecum located? Pylorus?
|
Right side
|
|
What is the opening of the ileum into the colon (not cecum)?
|
ileocolic (ileal) opening
|
|
# What is the course of the transveres colon in all domestic species?
|
right to left craial to root of mesentery
|
|
On which side of the animal is the descending colon
|
