Question 3

Rectovesical pouch:

Answer 3

Between rectum and urinary bladder
Where seminal vesicles are located

Question 4

Inner urethral sphincter

External urethral sphinter

Answer 4

Inner: controlled by parasympathetics. Where urethra begins. Just before prostate.

External: controlled by somatic nerves

Question 5

Prostatic utricle:

Answer 5

remnant of female, in seminal colliculus
ejaculatory duct drain in 2 small holes next to this.

Question 6

bulbourethral glands (cowper’s glands)

Answer 6

at membranous urethra
ducts of glands drain into spongy urethra
release secretion that cleans urine during sexual play, changes pH.

Question 7

retropubic space:

between pubic symphosis and prostate
bunch of fat

Question 8

Different zones of prostate

Answer 8

Anterior muscular zone
Transitional zone: more affected in cancer. overgrowth here. this in middle
Central zone: posterior
Peripheral zone: on bottom, most involved in cancer. Rectal examination can check prostate in peripheral zone.

Question 9

Prostatic sinuses

Answer 9

Next to seminal colliculus, filled with holes where prostate drains.

Question 10

Venous plexus around prostate connects with internal vertebral venous plexus

This is what is involved in metastasis of prostate cancer, to vertebrae, to brain.
