sperm successfully penetrates the mem-
brane surrounding the ovum, both sperm and ovum are

impenetrable to other sperm; this process is termed the **zona
reaction. **

Question 2

imately 35 years of a woman’s reproductive life.

fertilized egg contains 46 chromosomes (22 pairs autosomes/ 1 pair sex chromosomes)

Question 4

spermatogenesis

Answer 4

male reaches puberty, his testes begin the process

are called spermatocytes.

cells that undergo meiosis in the male

200 to 500 million
sperm

Question 5

Question 10

BLASTOCYST

Answer 10

whole structure of the developing embryo

Question 11

CHORIONIC VILLI

Answer 11

Finger-like projections developing out of the trophoblast & extend into the blood-filled spaces of the endometrium. These villi are vascular processes that **obtain oxygen & nutrients from the maternal bloodstream **& dispose of carbon dioxide & waste products in the maternal blood.

Question 12

DECIDUA BASALIS

Answer 12

after implantation the endometrium is called the decidua.

Question 13

FERTILIZATION

Answer 13
