Q
The boundaries of the perineum include all the following except: Ischiopubic rami Ischial tuberosity Tip of the coccyx Sacrotuberal ligament Sacrospinal ligament
A
sacrospinal ligament
2
Q
A condensation of fibrous tissue in the female located at the center of the posterior border of the perineal membrane is the: Frenulum Posterior labial commissure Perineal body Anococcygeal ligament Pubovesical ligament
A
perineal body
3
Q
The artery which supplies blood to the major erectile body in both the male and female is the: Artery of the bulb Dorsal artery of the penis/clitoris Deep artery of the penis/clitoris Posterior labial/scrotal artery Superficial external pudendal artery
A
Deep artery of the penis/clitoris
4
Q
The vestibular bulbs/bulb of the corpus spongiosum are firmly attached to the: Perineal membrane Superior pubic rami Ischiopubic rami Pubic symphysis Ischial tuberosities
A
Perineal membrane
5
Q
The part of the male reproductive tract which carries only semen within the prostate gland is the: Prostatic urethra Membranous urethra Seminal vesicle Ductus deferens Ejaculatory duct
A
Ejaculatory duct
6
Q
Which of the following developmental processes is least likely to be involved in the differentiation of male external genitalia from the indifferent state?
Descent of the gonads into the labio-scrotal folds
Fusion of the urogenital folds
Elongation of the phallus
Formation of new erectile bodies
A
Formation of new erectile bodies
7
Q
An intrahepatic blockage of the portal venous outflow may cause intestinal blood to drain via portal-systemic anastomoses into the: Superior gluteal vein Middle rectal vein Splenic vein Renal vein Inferior phrenic vein
A
Middle rectal vein
8
Q
What part of the ischioanal (ischiorectal) fossa extends deep to the sacrotuberal ligament? Anterior recess Genital hiatus Posterior recess Pudendal canal
A
Posterior recess
9
Q
The perineum is bounded by all of the following skeletal elements except: coccyx ischiopubic ramus spine of ischium symphysis pubis
A
spine of ischium
10
Q
A 6 mo. old male was brought to the pediatric clinic by his parents because of leakage of urine from the ventral surface of his penis. This congenital condition, hypospadias, is due to incomplete ventral closure of a component of the penis. Which of the below structures would be partially open for urine to take such a course? Shaft of corpus cavernosum Membranous urethra Glans Shaft of corpus spongiosum
A
shaft of the corpus spongiosum
11
Q
During childbirth a bilateral pudendal nerve block may be performed to provide anesthesia to the majority of the perineum and the lower one fourth of the vagina. To do this an anesthetic agent is injected near the pudendal nerve as it passes from the pelvic cavity to the perineum. The physician inserts a finger into the vagina and presses laterally to palpate what landmark? Arcus tendineus levator ani Coccyx Ischial spine Lateral fornix Obturator foramen
A
Ischial spine
12
Q
During a vaginal delivery, a surgeon performed median episiotomy in which he cut too far (i.e., through the perineal body into the structure immediately posterior). Which perineal structure did he cut? Bulbospongiosis muscle External anal sphincter muscle Ischiocavernosis muscle Sacrospinous ligament Sphincter urethrae
A
External anal sphincter muscle
13
Q
During a prostatectomy, the surgeon attempts to protect the prostatic plexus of nerves which contains nerve fibers that innervate penile tissue to cause erection. From which nerves do these fibers originate? Deep perineal Dorsal nerve of the penis Genitofemoral Pelvic splanchnics Pudendal
A
Pelvic splanchnics
14
Q
If the venous drainage of the anal canal above the pectinate line is impaired in a patient with portal hypertension, there may be an increase in blood flow downward to the systemic venous system via anastomoses with the inferior rectal vein, which is a tributary of the: External iliac Inferior gluteal Inferior mesenteric Internal iliac Internal pudendal
A
Internal pudendal
15
Q
A patient complains of a boil located on her labia majora. Lymphatic spread of the infection would most likely enlarge which nodes? Lumbar nodes Sacral nodes External iliac nodes Superficial inguinal nodes Internal iliac nodes
A
Superficial inguinal nodes
