Exam 2

Question 1

In both sexes, the Ilioinguinal N. passes through the inguinal canal on its way to innervate?

Answer 1

The anterior skin of the:
Labia Majora or Scrotum

Question 2

The cremasteric muscle fibers which loop down around the _____ and serve as the motor mechanism for the what?

Answer 2

The cremasteric muscle fibers which loop down around the testis serve as the motor mechanism for the cremasteric reflex

These fibers can be stimulated to contract and elevate the testis by scratching the skin of the lower abdominal wall or medial thigh with a fingernail or other semisharp object

Question 3

Any organ (name 3) which crosses the _____ will be displaced ANTERIORLY

Answer 3

Any organ which crosses the MIDLINE will be displaced ANTERIORLY

e.g. Left lobe of liver

Pyloric region

Neck of the pancreas

Question 4

Fluids w/in ABDOMINAL region of peritoneal cavity will tend to run off into what region?

From there, where will the fluids be directed and pool?

Answer 4

Abdominal fluids → Paravertebral gutters → Subphrenic, Subhepatic, & Perisplenic peritoneal recesses

Question 5

Fluids w/in PELVIC region of peritoneal cavity will tend to run off into what region?

From there, where will the fluids be directed and pool?

Answer 5

Pelvic fluids → Rectovesical (Male) or Rectouterine (Female) peritoneal pouches

Question 6

If any organ in the abdominal cavity is involved in an inflammatory process which has spread through its wall to involve the overlying peritoneum, the _____ ____ may randomly contact this inflamed surface and become involved in the inflammation and adherent to the inflammatory site. At times, therefore, it can help seal off or localize an abdominal inflammatory process

Answer 6

Omental apron

Question 7

Since the omental bursa is a cul de sac with only a narrow communication with the greater peritoneal cavity, and since it is gravitationally dependent in the supine position it can be the locus of a ________ ______ abcess

Answer 7

Since the omental bursa is a cul de sac with only a narrow communication with the greater peritoneal cavity, and since it is gravitationally dependent in the supine position it can be the locus of a peritoneal cavity abscess.

Question 8

The origin of an omental bursa abscess will likely be from…?

Answer 8

one of the organs in its walls

all of which have a relatively high incidence of inflammatory disease

Question 9

The _________ ____ is the obliterated Umbilican V.

Answer 9

Ligamentum Teres

Question 10

The ______ and _______ ligaments delimit four important peritoneal recesses around the liver. Because of their gravitational dependence in the supine position these recesses can puddle infectious material to produce subhepatic or subphrenic abscesses.

Answer 10

Falciform & coronary ligaments

Question 11

“Morrison’s Pouch,” aka

Answer 11

Right subhepatic recess

Question 12

In a supine patient infectious material derived from right‑sided organs like the gallbladder, right kidney, right side of the transverse colon, ascending colon, appendix, and duodenum can readily ascend the supine right paravertebral gutter to puddle in the __________ recess and potentially displace its bounding structures

Answer 12

Right Subhepatic recess

Question 13

Abscesses in any of these upper abdominal peritoneal recesses can irritate the _________ and, through the phrenic nerve ‑ C4 spinal cord segment‑supraclavicular nerve pain referral pathway cause referred pain to the ________ ______

Answer 13

Abscesses in any of these upper abdominal peritoneal recesses can irritate the diaphragm and, through the phrenic nerve ‑ C4 spinal cord segment‑supraclavicular nerve pain referral pathway, cause referred pain to the ipsilateral shoulder
