Chapter 20 (Exam 3) Flashcards
The movement of the testes by cremasteric action regulates A. Ejaculatory flow B. Sebaceous material production C. Testicular temperature D. Urinary flow E. Prostate gland secretion
C. Testicular temperature
The cremasteric muscle contracts and relaxes the scrotum. This action alters the distance of the testes from the body to cool or warm the testes.
What structure of the male genitalia travels through the inguinal canal and unites with the seminal vesicle to form the ejaculatory duct? A. Epididymis B. Corpus cavernosum C. Urethra D. Vas deferens E. Ureter
D. Vas deferens
The vas deferens begins at the end of the epididymis, travels the spermatic cord, goes through the inguinal canal, and then unites with the seminal vesicle to form the ejaculatory duct.
Normally, the male urethral orifice is located
A. 2mm ventral to the tip of the glans
B. On the dorsal surface of the glans
C. Cephalad to the dorsal vein
D. Adjacent to the prostate
E. On the ventral surface of the corpus spongiosum
A. 2mm ventral to the tip of the glans
While examine an 18y/o man you note that the penis and testicles are more darkly pigmented than the body skin. You should consider this finding to be A. Caused by a lack of testosterone B. Suggestive of a skin fungus C. Suggestive of psoriasis D. Caused by excessive progesterone E. Within normal limits
E. Within normal limits
Testicular temperature must be maintained lower than 37C for which of the following to occur? A. Penile erection B. Spermatogenesis C. Testosterone production D. Ejaculatory duct to function E. Sperm to ascend in the vas deferens
B. Spermatogenesis
In an uncircumcised male, retraction of the foreskin may reveal cheesy white material. This is usually A. Evidence of a fungal infection B. Collection of sebaceous material C. Indicative of penile carcinoma D. Suggestive of diabetes E. Evidence of a gonococcal infection
B. Collection of sebaceous material
The glans secretes a sebaceous material, smegma, in uncircumcised males. It looks like a cheesy white material. Smegma lubricates the cavity between the foreskin of the penis and the glans, allowing smooth movement between them during intercourse. Smegma is not candidiasis nor is it suggestive of diabetes, cancer, or gonorrhea.
The greatest contribution to the volume of ejaculate comes from the A. Prostate B. Epididymis C. Seminal vesicles D. Corpus cavernosa E. Testes
A. Prostate
Inspection of the scrotum should reveal A. No epidermoid cysts B. Two tests per sac C. Smooth scrotal sacs D. Left scrotal sac lower than the right E. Lightly pigmented skin
D. Left scrotal sac lower than the right
The left cord is longer than the right; consequently, the left testis hangs somewhat lower. The scrotum is more darkly pigmented, has one testis per sac, and has small epidermoid cysts that give it a lumpy appearance.
Sexual differentiation in the fetus has occurred by \_\_\_\_\_ weeks gestation. A. 8 B. 12 C. 16 D. 20 E. 30
B. 12
How much blood usually engorges the two corpora cavernosa of the penis when it is erect? A. 5-15ml B. 20-50ml C. 60-80ml D. 70-90ml E. Over 100ml
B. 20-50ml
Expected genitalia changes that occur as men age include
A. Ejaculatory volume decreases with age
B. Erections develop more quickly
C. Viability of sperm increases
D. Scrotum becomes more pendulous
E. Increase in time for mature sperm to develop
D. Scrotum becomes more pendulous
Ejaculatory volume may increase with age, erections develop more slowly, sperm viability decreases, and the scrotum becomes more pendulous with age. There is no change in the length of time necessary for mature sperm production.
Parents of a 6y/o boy should be asked if he has A. Erections B. Nocturnal emissions C. Rapid detumescence D. Scrotal swelling E. More pendulous scrotum
D. Scrotal swelling
Scrotal swelling, especially with crying or with bowel movements, signals the presence of a hernia. The question of nocturnal emissions is asked of adolescents; erections and rapid detumescence questions are questions for older men. With the onset of puberty, the scrotum becomes more pendulous.
Which of the following is a risk factor for testicular cancer? A. Circumcision B. Condyloma acuminatum C. Crytorchidism D. Poor hygiene E. Multiple sexual partners
C. Cryptorchidism
Cryptorchidism (testes that fail to descend by 12 months of age) is a risk factor for testicular cancer.
Gloves are used for examination of male genitalia to
A. Facilitate grasp of external organs
B. Makes masses easier to detect
C. Prevent spread of unsuspected infection
D. Protect the patient from embarrassment
E. Decrease the incidence of erections
C. Prevent spread of unsuspected infection
Inspection of male genitalia involves manipulation of the glans and scrotum. This potentially involves contact with body secretions and infections; therefore, gloves are required.
Inspection of the male urethral orifice requires the examiner to
A. Ask the patient to bear down
B. Insert a small urethral speculum
C. Press the glans between thumb and forefinger
D. Transilluminate the penile shaft
E. Apply a lubricant to the meatus
C. Press the glans between thumb and forefinger
Which penile structure should be visible to inspection during the physical exam? A. Cowper glands B. Proximal urethra C. Epididymis D. Corpus cavernosa E. Dorsal vein
E. Dorsal vein
