A&P of Reproductive System

Question 1

Why do Gametes differ from other cellular types?

Answer 1

They only include 1/2 of genetic material.

Question 2

Gametes include which types of cells?

Answer 2

Sperm and eggs (ovum)

Question 3

A zygote combines to form a full set of genetic material from what?

Answer 3

The uniting of sperm and egg nuclei

Question 4

What is produced in the testes?

Answer 4

Sperm

Question 5

Epididymis:

Answer 5

Tightly coiled tube on back of each testis where sperm mature.

Question 6

Pathway of sperm during sexual arousal:

Answer 6

Sperm go from epididymis through duct system of vas deferens, then through the prostate gland (prostate, seminal vesicle, bulbourethral gland add nutrients/lubricating fluid to create semen), then finally, urethra.

Question 7

How and where can fertilization occur in female?

Answer 7

Fertilization can occur if the sperm meets the egg by traveling through the cervix and continuing into the fallopian tubes where it can meet an ovum.

Question 8

Ovaries are what?

Answer 8

Female gonads that contain 100’s of immature eggs.

Question 9

The fallopian tube(s) are what?

Answer 9

Passageway into muscular uterus.

Question 10

Pathway of mature ovum:

Answer 10

Released from ovary, goes into fallopian tube and travels towards uterus.

Question 11

If fertilized, where will ovum implant?

Answer 11

Into the uterine endometrial lining.

Question 12

Purpose of placenta:

Answer 12

Maintains exchange of nutrients/wastes between mother and fetus.

Question 13

Full-term baby at how many week?

Answer 13

40 weeks.

Question 14

Pituitary gland is master control gland. It secretes FSH and LH, which stand for what?

Answer 14

Follicule-stimulating hormone and Luteinizing hormone.

Question 15

In males, FSH and LH serve what function(s)?

Answer 15

FSH promotes sperm production and LH controles production of testosterone in testes.

Question 16

In females, what is the basic role of FSH?

Answer 16

To stimulate beginning of menstrual cycle (in addition to accounting for female sex-characteristics).

Question 17

In a female, what occurs every 28 days?

Answer 17

The hormones of female system cause cyclic maturation of ova along with changes in uterine lining.

Question 18

Graafian follicules contain what?

Answer 18

Many immature eggs in the ovaries.

Question 19

FSH promotes development of follicule, triggering it to secrete estrogen, and also cause a surge in LH. What does this lead to?

Answer 19

Ovulation and rupturing of the egg from the follicule. Egg is then swept into fallopian tube.

Question 20

After ovulation, the empty Graafian follicule becomes known as what?

Answer 20

Corpus luteum

Question 21

Corpus luteum secrets what hormone?

Answer 21

Progesterone – which causes thickening of uterine lining. (w/o fertilization, lining wall will be shed in menses of menstrual cycle)
