theory quiz review

Question 1

cells in testes

Answer 1

1. seminiferous tubules
2. large interstital cells (leydig cells)
3. cells of sertoli (nurse cells)

Question 2

seminiferous tubules

Answer 2

found in testes

produce spermatoza

Question 3

large interstitial cells (Leydig cells)

Answer 3

produce the male sex hormone testosterone

Question 4

cells of sertoli
(nurse cells)

Answer 4

contain glycogen for the nourishment of sperms

secrete inhibin
inhibits the production of Follicle Stimulating Hormone by the anterior pituitary

Question 5

sperm production where

Answer 5

seminal glands

Question 6

nurse cells functions

Answer 6

1. maintain blood-testis barrier
   blood-testis barrier
   isolates seminiferous
   tubules
2. support mitosis and meiosis
   stimulated by: follicle
   stimulating hormone
   testosterone
3. support of spermiogenesis
   surround and enfold
   supplements
4. secrete inhibin
   depresses: pituitary
   production of FSH
   hypthalamic
   secrention of GnRH
   regulation of FSH and
   GnRH
5. secretion of androgen-binding protein (ABP)
   binds androgens
   production of ABP
   is stimulated by FSH
6. secretion of Mullerian-inhibiting factos (MIF)
   causes regression of
   fetal mullerian ducts

Question 7

inadequate Mullerian-inhibiting factor (MIF)

Answer 7

retention of ducts

failure of testes to descend into scrotum

Question 9

how are sperm transported through vas deferens

Answer 9

peristalsis

Question 29

secretion of prostate gland

Answer 29

slightly acidic

Question 30

secretion of bulbourethral gland

Answer 30

thick alkaline mucus

Question 31

scrotum

Answer 31

cooler temp for sperm to survive 2 degrees less than body temp

Question 32

3 accessory glands

Answer 32

seminal glands: 60% alkaline prostate gland: slighlty acidic bulbourethral gland: (couper's gland) alkaline

Question 33

puberty

Answer 33

hypothalamis gonadotropin releasing hormone adenohypophsis (anterior pituitary) FSH, LH male testes sperm, testosterone secondary sexual characteristics laryngeal changes-deep voice growth of pubic, axillary, facial hair increase in muscle and skeletal mass and male shape of body sex drive, aggression, etc increased sebaceous gland secretion
