|

|
inferior part of the rectum
|
|
The pectinate line is the place where the
|
the lining of the anal canal changes from skin to mucosa. It is also a landmark that divides the lymphatic drainage, vascular supply, and innervation of the anal canal. Lymph coming from structures above the pectinate line drains to the inferior mesenteric lymph nodes or the internal iliac nodes. Lymph from structures below the pectinate line travels to the superficial inguinal lymph nodes.
As far as vasculature and nerves go... Superior to the pectinate line, arterial blood comes from the superior rectal artery and drains to the portal system through the superior rectal veins. This area is innervated by the inferior hypogastric plexus (autonomic innervation). Inferior to the pectinate line, blood comes from the inferior rectal arteries and is drained into the caval system. Innervation here comes from the inferior rectal nerves (somatic innervation). |
|
The anorectal junction is the point where the rectal ampulla narrows due to
|
a U-shaped sling created by the puborectalis muscle. This area is superior to the pectinate line. The white line is a transitional area inferior to the pectinate line that represents some subtle changes as the mucosal lining becomes "regular" skin.
|
|
under normal conditions, where does fertilization take place ?
|
ampulla of the uterine tube- the longest and widest segment
|
|
what rectal structure is only found in males?
|
The rectovesicular pouch is a reflection of the peritoneum between the rectum and the bladder. It can only be found in males because females have the uterus sitting between the rectum and the bladder.
|
|
A 27-year-old woman is examined by her gynecologist. Upon rectal examination, a firm structure, directly in front of the rectum in the midline, is palpated through the anterior wall of the rectum. This structure is the:
|
The cervix of the uterus is anterior to the rectum. Since the cervix is the inferior part of the uterus that is protruding into the vagina, it should feel like a firm structure upon palpation. The bladder is the most anterior organ in the pelvis, in front of the uterus and rectum. So, the bladder would not be directly in front of the anterior wall of the rectum
|
|
is the prostate extraperitoneal?
|
yes
|
|
Structures within the lower gastrointestinal tract specialized for physical support of fecal material are the
|
There are usually three transverse rectal folds in the lower rectum. These are specializations of the circular layer of musculature that are designed to support fecal mass. Although circular folds is somewhat descriptive of the transverse rectal folds, this is not the best answer. Anal columns are longitudinal folds of mucosa over rectal vessels. They are found on the inner wall of the anal canal. Anal valves are the folds of mucosa that join the anal columns at their inferior ends.
|
|
Which of these features of the anal canal serves to indicate the point where the mucosal covering of the gastrointestinal tract ends and a skin-like covering begins?
|
The pectinate line is the line of transition between the mucosal lining of the anal canal and the skin lining of the anal canal. So, this is the point where the mucosal zone ends and the skin begins. The white line is a transitional zone between the pectinate line and "regular" skin where there are some more subtle changes in the epithelial lining of the anal canal. But the pectinate line is the line that demarcates the major transition from mucosal lining to skin.
|
|
A female patient is found to have an ectopic (tubal) pregnancy (embryo develops in the uterine tube). In order to gain access to the peritoneal cavity endoscopically to remove the embryo, the instrument can be passed into the vagina and through the:
|
This means that an incision made through the posterior fornix of the vagina will allow a surgeon to enter the rectouterine pouch of the peritoneal cavity and remove the embryo.
|
|
An elderly patient is having difficulty in voiding (urinating). He complains that after voiding, he still feels as though he needs "to go" again. You suspect that this patient suffers from benign prostatic hypertrophy, which has caused enlargement of the __________ of the bladder.
|
uvula
|
|
The part of the broad ligament giving attachment and support to the uterine tube is the:
|
mesosalpinx
|
|
is the femoral nerve in the true pelvis?
|
NNNOOOO
To answer this question, you need to understand what the true pelvis is. The true pelvis is the area beneath the pelvic brim (pelvic inlet), where the pelvic viscera are located. The false pelvis is the area above the pelvic brim, bounded by the iliac blades. Now, you just need to think about the structures listed and determine which ones are in which location. The femoral nerve is the structure that is not in the true pelvis. After coming off the lumbar plexus with contributions from L2, 3, and 4, the femoral nerve runs along the border between the psoas major muscle and the iliacus to travel into the lower limb. It never descends below the pelvic brim, so it is not in the true pelvis. |
|
A structure which is homologous to the male scrotum
|
The labia majora and scrotum are homologous structures. The labia minora is the female counterpart of the pentscrotal raphe. The glans of the clitoris and glans of the penis are homologous structures. Finally, the shaft of the corpus cavernosum in the female is the shaft of the clitoris, which is homologous to the shaft of the penis.
|
|
4 major differences between the male and female pelvis
|
There are four major differences between the male and female pelvis. First, the subpubic angle and pubic arch are greater in the female pelvis than in the male pelvis. This is why A is correct-- females often have a subpubic angle of 90 degrees or greater. A second difference between the female and male pelvis is that the pelvis inlet for females is rounded, while for males it is heart shaped. Third, the pelvic outlet for females is larger than in males. Finally, the female pelvis has iliac wings that are more flared than in males.
|
|
You are observing a doctor perform an abdominal hysterectomy. He notes that it is vital to protect the ureter which is found in the base of the:
|
The mesometrium is the part of the broad ligament of the uterus that attaches the body of the uterus to the pelvic wall. The ureters pass through the base of the mesometrium as they travel to reach the bladder.
|
|
rectouterine pouch is the lowest extent of the female peritoneal cavity. At its lowest, it provides a coat of peritoneum to a portion of the
|
In females, the rectouterine pouch is a peritoneal fold reflecting from the rectum to the posterior fornix of the vagina. At its lowest extent, the rectouterine fold is draped over the posterior fornix of the vagina. This means that surgeons can make an incision in the posterior fornix of the vagina and enter the rectouterine pouch to harvest eggs from the ovaries or remove an ectopic pregnancy. Take a look at Netter Plate 337 for a picture of this relationship
|
|
In a CT scan of the pelvis, the uterus is located:
|
In the female pelvis, the bladder is the most anterior organ; the uterus is posterior to the bladder, and the rectum is posterior to the bladder and uterus.
