Q

What do Leydig (intestinal endocrine cells) produce

A

Q

What do Nurse (Sertoli) cells produce

A

Inhibin

18
Q

What do spermatogenic cells produce

A

19
Q

Describe the epididymis

A

Sperm enters from seminiferous tubules - exit via ductus deferens
Site of sperm maturation

20
Q

Describe the ductus deferens (vas deferens)

A

Continues from epididymis - starts in spermatic cord

Covered by smooth muscle - behins urinary bladder - dilates to form ampulla

21
Q

Describe ejaculatory ducts

A

Formed by union of duct from seminal vesicle and ampulla - Opens in prostatic urethra

22
Q

A

Urination and ejaculation

23
Q

What are the epithelium changes of the urethra

A

Transitional
Columnar
Stratified squamous

24
Q

What are the three sections of the male urethra

A

Prostatic
Membranous
Penile/spongy

25
Q

What are the two urinary/renal sphincters

A

External - skeletal - voluntary

Internal - Ensuring sperm ejaculated

26
