Question 44

Seminiferous tubules - cells associated with them and what they do

Answer 44

- Interstitial endocrine (leydig) cels produce testosterone - nurse (sertoli) cells produce inhibin - supermatogenic cells - spermatogonia and spermatozoa at various stages of development

Question 45

- prostatic urethra - membranous urethra - penile/spongy urethra

Question 60

Urethral sphincters - external and internal

Answer 60

- external: skeletal muscle, voluntary control of urination - internal: detrusor muscle: closes bladder ensuring sperm ejaculated through the urethra (Retrograde ejactulation: sphincter doesn’t close; therefore, sperm ends up in bladder)

Question 61

Retrograde ejaculation:

Answer 61

- sphincter doesn’t close; therefore, spermicide ends up in bladder
