Answer 4

Chemical compounds that control development or function of reproductive system
•primary
•secondary

Question 5

The testes -external

Answer 5

• the testes
• scrotum
• seminiferous tubules
• sertoli cells
• epididymis
• ductus deferents
• ejaculatory duct

Question 6

Testes (plural)

Answer 6

Two male gonads

-OUTSIDE body ——-scrotum

Question 7

Scrotum

Answer 7

Pouch of skin OUT of the body holding the testes
•regulates temperature (success at 35 C)
-cold=clings close
-hot= loosely away

Question 8

Seminiferous tubules

Answer 8

Long/coiled tubes IN the TESTES
•hormone secreting cells called 
{interstitial cells} rest between the tubes.
•secrete testosterone 
•sperm producing

Question 9

Sertoli cells

Answer 9

SUPPORTING cells
•nourish developing sperm cells
-line seminiferous walls

Question 10

Epididymis

Answer 10

In each testes/ speed are transported to this duct
-sperm become mature and motile here
•stored

Question 11

Ductus Deferens

Answer 11

Storage duct
•connected to epididymis
•leads to penis

Question 12

Ejaculatory duct

Answer 12

Leads deferens to PENIS
•also “vas deferens”
-mature and store sperm
-carried sperm to penis (in the scrotum)

Question 13

The penis -external-

Answer 13

• penis

* foreskin

Question 14

Penis

Answer 14

Male organ used for sexual intercourse
•transfer speed from male to female tract
•enlarged tip called glans penis

Question 15

Foreskin

Answer 15

Surround penis in a sheath of skin
•no function for reproduction—— circumcision
-erect due to arousal =blood flow

Question 16

Seminal fluid

Answer 16

• seminal vesicle
• prostate gland
• semen
• urethra
• ejaculation
• cowpers gland

Question 17

Seminal vesicle

Answer 17

Produce mucus like fluid
-contains FRUCTOSE
—-provides NRG for sperm

Question 18

Prostate gland

Answer 18

Secrete mucus fluid to neutralize urine acids (urethra)
•pH
-alkaline and mucoid fluid

Question 19

Cowper’s gland

Answer 19

Mucus like fluid
•lubricant
•alkaline and mucoid fluids to semen

Question 20

Semen

Answer 20

Combination of sperm cells and fluids
-enters urethra
(Parasympathetic and sympathetic)

Question 21

Urethra

Answer 21

Is a duct that carried fluid through the penis
-semen enters through ductus deferens
•shared urinary and repro system

Question 22

Ejaculation

Answer 22

Sensory stimulation/arousal/co-ordinated muscular contractions ALL combine to trigger ejaculations
•semen leaves penis (target: vagina)

Question 23

Sperm cells

Answer 23

Carried genetic material from father
(23chromosomes)
~100 million sperm per day

Question 24

Sertoli cells

Answer 24

INSIDE the tubules beside the maturing spent and provided nourishment

Question 25

Interstitial cells

Answer 25

Located OUT the tubules and secretes TESTOSTERONE | -triangle shaped

Question 26

Pathway males

Answer 26

``` Spermatogenesis (In seminiferous) -epididymis -ductus deferens -seminal vesicle -prostate -cowpers -ejaculatory duct—->urethra ```

Question 30

Ovary

Answer 30

Internal -produce limited gametes in life -make and store the Ova (EGG) -provide safe environment for fertilization/nourishment for fetus •OOGENESIS •FEMALE HORMONES (progesterone&estrogen)

Question 31

Meiosis

Answer 31

Zygote (2n)

Question 32

Follicles

Answer 32

SINGLE ovum develops within it •each month 1 mature follicle releases 1 I un into oviduct •ovulation= if egg fertilizes a corpus luteum is present
