Question 5

Ductus Deferens

Answer 5

Travels from tail of epididymis – through inguinal canal – into pelvic – swells to ampulla of DD – joins with ducts of seminal vesicles post. to bladder to form ejaculatory ducts

Cremasteric fascia (int. oblique m. aponeurosis)
Internal spermatic fascia (transversalis fascia)

Question 8

Layers of testis

Answer 8

Tunica vaginalis (parietal and visceral)
Tunica albuginea

Question 9

Testis

Answer 9

Contains: seminiferous tubules, straight tubule, rete testis, septum

Question 10

Path of sperm in testis

Answer 10

Formed in seminiferous tubules – straight tubule – transferred to rete testis (sperm enter efferent ductules of epididymis) – septum (b/w seminiferous and straight tubules)

Question 11

Epididymis

Answer 11

Head (w/ lobules), Body, Tail, Efferent ductules

Question 12

Deep Fascia of penis

Answer 12

Surrounds erectile tissue and deep vasculature (deep perineal fascia)

Answer 13

Is attached to bulb and crura of penis, bulbospongiosus m., and ischiocavernous m.

Question 14

Body of penis

Answer 14

Includes connective tissue, paired corpora cavernosa, corpus spongiosum and spongy urethra

Question 15

Glans penis

Answer 15

Continous with corpus spongiosum

Question 16

Question 19

External urethral orifice

Answer 19

Question 20

Prepuce

Answer 20

Foreskin (along with frenulum ventrally located medial fold)

Question 21

Prostate gland

Answer 21

• Unpaired, accessory gland
• Produces prostatic fluid (20% of seminal fluid)
• Prostatic ducts convey prostatic fluid from parenchyma of gland to prostatic sinus

Question 22

Enlarged prostate gland

Answer 22

• Occurs with increasing age, and can impinge on prostatic urethra
• Dx via DRE (along with prostate cancer)

Question 23

Seminal vesicles

Answer 23

• Paired, elongated structures between urinary bladder and rectum
• Secrete a fluid that is a part of semen (secretes into ejaculatory duct)

Question 24

Ejaculatory ducts

Answer 24

• Begin @ union of ampulla of ductus deferens and ducts of seminal vesicles (near neck of bladder) and converge just before prostatic urethra
• Empty into prostatic urethra @ seminal colliculus

Question 25

Bulbourethral glands

Answer 25

Pea-sized glands positioned posterolateral to membranous urethra and produce mucus like substance during sexual arousal

Question 26

Deferentectomy/Vasectomy

Answer 26

Ligation/excision of ductus deferens through incision in superior scrotum – ejaculant devoid of spermatozoa
