Which pair of structures does NOT differentiate from comparable embryonic structures in the male and female? Bulb of corpus spongeosum and vestibular bulb Shaft of penis and labia majora Glans of penis and glans of clitoris Crus of corpus cavernosum penis and crus of corpus cavernosum clitoris
Which structure is found only in males? Anterior recess of ischoianal fossa Genital Hiatus Ischiocavernosus muscle Rectovesical pouch Sphincter urethrae muscle
Which structure is outlined with contrast on a CT using intraperitoneal contrast
material? Ovary Prostate Rectum Seminal Vesicles Vagina
The prostate is often imaged using an ultrasound transducer placed in which location? Penis Perineum Rectum Urethra Urinary Bladder
Which of the following does not conduct spermatozoa? Ampulla of the ductus deferens Duct of the seminal vesicle Epididymis Prostatic Urethra
During the course of surgery for benign prostatic hypertrophy (benign enlargement of the prostate tissue which occludes the prostatic urethra) an electrical cutting device is inserted into the penile, then prostatic urethra, to remove the hypertrophic tissue. The posterior wall of the prostatic urethra is by necessity removed as well. Which part of the male seminal tract may also be partially removed? duct of seminal vesicle ductus deferens ejaculatory duct fossa navicularis seminiferous tubule
The prostate gland: Contains upper, middle and lower lobes Encircles the urethra Is well imaged radiologically using an intravenous urogram Is extraperitoneal B and D
During a vasectomy, the ductus deferens is ligated in the superior part of the scrotum. Two months following this sterilization procedure, the subsequent ejaculate contains: Prostatic fluid only Seminal fluid and prostatic fluid Sperm only Sperm and seminal fluid Sperm, seminal fluid, and prostatic fluid
An elderly male patient presents with dysuria and urgency. You suspect benign prostatic hypertrophy which has caused an enlargement of the: interureteric crest prostatic utricle seminal colliculus sphincter urethrae uvula
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. seminal colliculus interureteric crest ampulla trigone uvula
The prostate gland: encircles the urethra is well imaged using an intravenous urogram is partially intraperitoneal contains upper, middle and lower lobes
Which structure is NOT found within the true pelvis? Femoral nerve Hypogastric nerve Internal pudendal artery Obturator artery Pelvic splanchnic nerves
A structure which is homologous to the male scrotum: Labia minora Labia majora Glans Shaft of corpus cavernosum
The male pelvis tends to differ from the female pelvis in that the male pelvis often has a: larger pelvic inlet smaller subpubic angle straighter sacral curvature larger pelvic outlet rounder pelvic inlet
The boundaries of the perineum include all the following except: Ischiopubic rami Ischial tuberosity Tip of the coccyx Sacrotuberal ligament Sacrospinal ligament
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
The vestibular bulbs/bulb of the corpus spongiosum are firmly attached to the: Perineal membrane Superior pubic rami Ischiopubic rami Pubic symphysis Ischial tuberosities
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
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
The perineum is bounded by all of the following skeletal elements except: coccyx ischiopubic ramus spine of ischium symphysis pubis
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
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
