Viscera (Exam 2) Flashcards
Esophagus to the Rectum - GO
Esophagus -> cardiac portion of stomach -> fundus -> body -> pyloric portion -> pylorus (sphincter) -> duodenum -> cranial duodenal flexure -> descending duodenum -> caudal duodenal flexure -> ascending duodenum -> duodenaljejunal flexure -> jejunum -> ileum -> ileocolic orifice -> cecum -> cecocolic orifice -> ascending colon -> right colic flexure -> transverse colon -> left colic flexure -> descending colon -> rectum
Lobes of the liver R to L
R lateral, R medial, Quadrate, L medial, L lateral, Caudal
Where does the gallbladder reside
between the R median and quadrate lobes of the liver
What is the suspensory ligament of the uterus and why is it clinically important?
It holds the ovary in a relatively fixed position. This ligament must be freed from the body wall in oviohysterectomy (spay)
What is the proper ligament of the ovary?
attaches the ovary to the cranial end of the uterine horn
What are the broad ligaments of the uterus?
peritoneal folds on each side that attach to the lateral sublumbar region. They suspend the internal genetialia (except the caudal part of the vagina)
Which kidney is more cranial? R or L?
The R kidney
What is the hilus of the kidney?
where the renal vessels and nerves and the ureter communicate with the organ
Which is more central in a kidney- the medulla or the renal cortex?
the medulla
What is the renal crest of the kidney?
where collecting tubules excrete urine into the renal pelvis
What is the renal pelvis of the kidney?
the expanded portion of the ureter
What is the renal sinus of the kidney?
the fat filled space that contains the renal vessels and surrounds the renal pelvis
Where does the bile duct enter?
Where does it terminate?
enters the descending duodenum, terminates on the major duodenal papilla next to the pancreatic duct
The pericardial cavity lies between which of these layers?
a. pericardial mediastinal pleura
b. parietal serous pericardium
c. fibrous percardium
d. epicardium (visceral serous pericardium)
b and d
During a physical exam on a dog you palpate a somewhat moveable, fairly firm, ovoid 2 cm structure located deep to the deep pectoral muscle. Based on your knowledge of gross anatomy you identify the structure as the ? lymph node .
axillary
In a normal animal, which of the following would you expect to find in the pleural cavity?
a. the esophagus
b. the heart
c. the lungs and trachea
d. a small amount of serous fluid
d
You are presented with an animal with severely decreased blood pressure due to blood loss, which is making it virtually impossible to use a peripheral vein for venipuncture.
To give this animal an injection as part of the emergency treatment, you resort to an injection directly into the right ventricle, taking advantage of the __?__ between adjacent right lung lobes.
cardiac notch
The second heart sound, S2, occurs at what point during the cardiac cycle?
when the aortic and pulmonic valves are closed
The heart sound, S1, occurs at what point of the cardiac cycle?
When the AV valves close
Which valves open and close during diastole?
AV valves open
Aortic and Pulmonic valves close
Which valves open and close during systole?
AV valves close
Aortic and Pulmona valves open
What happens during diastole?
atria and ventricles fill
What happens during systole?
ventricles contract
