Male Genital System

1-The order of ducts in the male genital system: *

Rete testis- Tubuli recti- Vasa efferentia- epididymis

Tubuli recti- Rete testis- Vasa efferentia- epididymis

Tubuli recti- Rete testis- Vasa efferentia- Ejacutatory duct

2. Rete testis is lined by *

Simple cuboidal epithelium

Simple columnar epithelium

Festooned epithelium

Simple columnar ciliated epithelium

Pseudostratified columnar ciliated epithelium

3. Which gland is responsible for most of the semen released in an ejaculation? *

seminal vesicles

bulbourethral gland

prostate gland

glans penis

4. Which gland releases a small amount of fluid just prior to ejaculation to decrease acidity in the urethra caused by urine? *

prostrate gland

glans penis

bulbourethral gland

seminal vesicles

5. Consider the pathway traversed by sperm. Which of the following is INCORRECT? *

Motile sperm leave the seminiferous tubules via straight tubules that openinto the rete testis of the mediastinum testis

From the rete testis the sperm travel via the ductuli efferentes into the ductus epididymidis where they mature

At ejaculation the smooth muscle of the epididymidis propels the sperm into the muscular ductus deferens

From the ductus deferens the sperm traverse the ejaculatory duct throughthe substance of the prostate into the prostatic urethra

All are correct

6. Consider the male excurrent duct system. Which of the following is INCORRECTLY matched?

rete testis--simple cuboidal epithelium

ductuli efferentes--pseudostratified epithelium with tall columnar ciliated cells and nonciliated cuboidal cells

ductus epididymidis--pseudostratified columnar with stereocilia

ductus deferens--simple columnar ciliated epithelium

penile urethra--stratified columnarepithelium interspersed with patchesof pseudostratified columnar with moist stratified squamous epithelium near the meatus
