Answer 8

gamete formation

Question 9

Process of formation and development of
specialized generative cells, gametes
(oocytes/sperms) from ??

Answer 9

bipotential precursor cells

Question 10

during gametogenesis what happens to chromosome number

Answer 10

reduced by half and the shape of the cell is altered

Question 11

sperm with two heads ?

Answer 11

abnormal ;as many as 10 precent of sperms ejaculated are grossly and they do not fertilize

Question 12

pathogenic
process called nondisjunction; cause

Answer 12

homologous chromomsomes fail to seprate and they fertilize

Question 13

is the sequence of events by which oogonia primordial germ cells are transformed into mature occytes

Answer 13

oogenesis

Question 14

all oogina develop into primary occyte ?

Answer 14

before birth

Question 15

completion of prophase1 does not ocuur until?

Answer 15

adolescence

Question 16

abnormal oogenesis
frequency of nondidjunction increases with ?

Answer 16

the increased age of women

Question 17

what is the function of GnRh

Answer 17

stimulates the release of LH and FSH

Question 18

what stimulates the development of ovarian and the production of estrogen by the follicular cells?

Answer 18

follicle stimulating hormone FSH

Question 19

what is the function of LH

Answer 19

luteinizing hormone
1 serves as the trigger for ovulation which is release of secondary oocte
2 stimulates the follicular cells and corpus luteum to produce progesterone

Question 20

changes in the estrogen and progestrone levels causes ?

Answer 20

cyclic changes in the structure of the famale reproductive tract

Question 21

menstrual phase

Answer 21

• usually lasts 4 to 5 days
  the functional layer of the uterine wall is sloughed off discarded with monthly bleeding
• the blood discharged from vagina is combined with small pieces of endometrial tissue

-atefr menstruation the eroded endometrium is thin

Question 22

proliferative phase?

Answer 22

lasts approximately 9 days

Coincides with the growth of
ovarian follicles and
• Is controlled by estrogen secreted
by the follicles.
• There is a two- to three-fold
increase in the thickness of the
endometrium and in its water
content during this phase of repair
and proliferation

Question 23

Luteal Phase

Answer 23

The luteal (secretory phase), lasts
approximately 13 days,
• Coincides with the formation,
functioning, and growth of the corpus
luteum.
• The progesterone produced by the
corpus luteum stimulates the glandular
epithelium to secrete a glycogen-rich
material.
• The endometrium thickens because of
the influence of progesterone and
estrogen from the corpus luteum
