female repro I

Question 1

reproductive system - survival? functional when?

Answer 1

• not necessary for survival of the individual, but necessary for the species
• other systems of body functional at/shortly after birth
• repro becomes functional at puberty

Question 2

Functions of Female repro system (7)

Question 3

Functions of Male Repro

Answer 3

1. production of male gametes - spermatozoa
2. delivery of male gametes to female reproductive tract

Question 4

Answer 4

Question 5

Subdivisions of Repro System

Question 6

integration

Answer 6

• function of different components of repro system integrated by:
• pituitary and ovarian hormones
• complex neurological pathway

Question 7

Answer 7

Question 8

uterus - direction/bending?

Answer 8

• anteverted: tipped forward
• anteflexed: body of uterus bent forward

Question 9

Answer 9

Question 10

Answer 10

Question 11

Follicle develooment - # enter development vs maturity?

Answer 11

• multiple primordial follicles enter development at same time
• only one follicle reaches maturity and is ovulated
• remainder degenerate by process of atresia

Question 12

Answer 12

Question 13

Follicle development stimulated by?

Answer 13

FSH from ant pit

Question 14

Answer 14

Question 15

Endocrine Function of Follicle

Answer 15

• theca and granulosa cells together secrete estrogen
• estrogen enters capillary bed within theca and circulates throughout body
• estrogen: supports regrwoth of endometrium after menstration

Question 16

Function of non-ovulated follicles

Answer 16

• amount of estrogen secreted is a function of size of follicle
• many small follicles are required in early stages of ovarian cycle to secrete required estrogen
• as follicles enlarge, one becomes dominant and takes over estrogen secretion

Question 17

Ovulation: follicle? estrogen? etc finish pathway

Answer 17

• as follicle matures and enlarges, it secretes increasing amounts of estrogen
• high concentation of estrogen causes ant pit to secrete LH
• LH induces final maturation and ovulation of follicle

Question 18

Ovulation - order of events

Question 19

Function of Corpus Luteum

Answer 19

• temporary endocrine organ
• secretes estrogen and progesterone
• progesterone prepares endometrium for implantation of embryo
• progesterone required for maintenance of endometrium

Question 20

Fate of Oocyte - during ovulation? capturated how?

Answer 20

• during ovulation: infundibulum and fimbria sweep over surface of ovary
• oocyte captured by infundibulum and transported into fallopian tube by ciliated epithelium

Question 21

Fate of Oocyte - transport down tube? fertilization? then?

Answer 21

• oocyte transported down fallopian tubes by ciliated epithelium and contractions of smooth mucle in wall of fallopina tube
• ferilization takes place in ampulla of F. tube
• ferilized zygote travels down FT to uterus, implants in mucosa

Question 22

Chorionic Gonadotrophic Hormone

Answer 22

• made by cells of implanted embroy (chorion)

Question 23

corpus luteum secretory during? then what takes over?

Answer 23

• corpus luteum remains secretory throughout first trimester
• placenta takes over secretion of progesterone and estrogen
