Question 0

Tunica Albugina

Answer 0

white connective tissue on testes

Question 1

Testes

Answer 1

3-5 degrees lower than normal for good sperm production, (Gonads) about the size of a small egg.

Question 2

seminiferous tubules

Answer 2

compartments filled with tubes; the tubes PRODUCE sperm; make testosterone?

Question 3

Epididymis

Answer 3

sits on top of testes, another extension for the tubes, Function: immature eggs get sent there

Question 4

scrotum

Answer 4

external sac of skin, subcutaneous tissue, holds testes, wall separates the left and right scrotum

Question 5

Cremaster muscle

Answer 5

circles the scrotum and the testes; also brings closer and farther away when needed. Smooth muscle

Question 6

Vas Deferens

Answer 6

run from epididymis up to inguinal canal then up and back through to side of urinary bladder. Function: storage until next ejaculation or if not, absorb back into the body

Question 7

Ejaculatory duct

Answer 7

transports sperm out, carries sperm from epididymis to outside world, where vas deferens and seminal vesicles join

Question 8

Penis

Answer 8

made of erectile skin, allows for sexual intercourse. There is a prepus on the penis, fits on distal end of penis. Removal of the prepus is called circumcisim.

Question 9

Prostate gland

Answer 9

size of a nut, urethra goes through middle of prostate, small. Function: secreting white alkaline liquid substance. (adds alkalinity to sperm and semen)

Question 10

Cowpers Glands (bulborethra glands)

Answer 10

finish off amount of semen, secrets alkaline liquid, very mucoid, on one ejaculation, 2-6 mL of semen is let out
100 million sperm per mL of semen

Question 11

urethra

Answer 11

produces hormones

Question 14

Follicle stimulation hormone

Answer 14

target organ is seminiferous tubules

Question 15

Interstitial Cell stimulation hormone (icsh)

Answer 15

cells of connective tissue that holds cells together, layer of tissue that lies between seminiferous tubules( make testosterone) then testosterone gets into blood stream

Question 16

cryptoorchidism

Answer 16

Hidden testes; surgical intervention to drop testes; Hole in abdominal wall for spermatic cord to go through

Question 17

cremaster reflex test

Answer 17

Question 19

spermatic cord

Answer 19

testicular artery/vein/nerve and lymph vessle, cassed in connective tissue then the cremaster muscle then the skin

Question 20

Answer 20

responsible for some semen, vas deferens hook onto, makes 60% of semen

Question 21

Semen (in it)

Answer 21
