Anatomy Chapter 27 Part 2

Front 1

where the ovum/ egg is produced

Back 1

ovaries

Front 2

ovum travels through this to uterus-- fertilization takes place here

Back 2

uterine tubes

Front 3

implantation takes place here

Back 3

uterus

Front 4

opens to external genitalia

Back 4

vagina

Front 5

this is an extensive mesentery that encloses ovaries, uterine tubes, uterus

Back 5

broad ligament

Front 6

mesovarium

Back 6

ovaries

Front 7

mesosalpinx

Back 7

uterine tubes

Front 8

broad ligament proper

Back 8

uterus

Front 9

what are the 2 pouches that are created by the broad ligament

Back 9

rectouterine pouch
vesicouterine

Front 10

this pouch is between uterus and rectum

Back 10

rectouterine

Front 11

this poud is between the bladder and uterus

Back 11

vesicouterine

Front 12

paired organ responsible for production for ova/eggs and secretion of hormones

Back 12

ovary

Front 13

supports the ovary and is located between the ovary and uterus

Back 13

ovarian ligament

Front 14

supports the ovary and is located between the ovary and lateral pelvic wall
- contains ovarian artery and vein

Back 14

suspensory ligament

Front 15

what are the 4 layers of the ovary (outside to inside)

Back 15

visceral/ germinal epithelium
tunica albuginea
cortex
medulla

Front 16

production of ova on a monthly basis -- part of ovarian cycle

Back 16

oogenesis

Front 17

this structure completes mitotic division prior to birth so all primary oocytes are present at birth

Back 17

oogonia

Front 18

where are oogonia located?

Back 18

ovarian cortex in egg nest

Front 19

what surrounds each primary oocyte?

Back 19

follicular cells called primordial follicle

Front 20

most primary oocytes degenerate and become what?

Back 20

atretic follicles

Front 21

what is the first step of the ovarian cycle?

Back 21

primordial follicles become primary follicles

Front 22

what hormone is secreted in the 1st step of the ovarian cycle?

Back 22

estrogens

Front 23

the following are functions are what hormone?

- stimulates bone and muscle growth
-maintain secondary female sex characteristics
- influences sex related behaviors and drives
- maintains reproductive glands
- initiates repari and growth of uterine lining

Back 23

estrogen

Front 24

what is the 2nd step of the ovarian cycle?

Back 24

formation of primary follicle into secondary follicle

Front 25

what is the 3rd step of the ovarian cycle?

Back 25

secondary follicle develops into tertiary follicle

Front 26

which estrogen is most important
- dominant hormone prior to ovulation

Back 26

estradiol

Front 27

another name for a tertiary follicle

Back 27

mature ovarian follicle and graafian follicle

Front 28

at what stage does primary oocyte divide into secondary oocyte and polar body? and if fertilization occurs then ovum and polar body..

Back 28

step 3 of ovarian cycle

Front 29

this is the 4th step of the ovarian cycle

Back 29

gamete release-- ovulation

Front 30

follicular cells surround the oocyte are known as...... after the secondary oocyte breaks free

Back 30

corona radiata

Front 31

period between the start of the cycle and the completion of ovulation...anywhere between 7-28 days

Back 31

follicular phase

Front 32

what is the 5th step in the ovarian cycle

Back 32

formation of corpus luteum

Front 33

this is the 5th step of ovarian cycle

Back 33

formation of corpus luteum

Front 34

this is the 6th step of the ovarian cycle

Back 34

formation of corpus albicans

Front 35

hollow muscular tube that is divided into the infundibulum, ampulla, and uterine part
- function to transport the secondary oocyte to either become fertilized or degenerate

Back 35

uterine tubes

Front 36

part of uterine tubes closest to ovary
- expanded funnel with fimbriae with cilia

Back 36

infundibulum

Front 37

part of uterine tube where fertilization usually takes place

Back 37

ampulla

Front 38

part of uterine tubes that connects to uterus

Back 38

uterine part

Front 39

strong muscular organ which serves as protection, nutrition, support, and waste removal of developing embryo if ovum fertilized

Back 39

uterus

Front 40

these ligaments support the uterus (3)

Back 40

broad, round, lateral/ cardinal

Front 41

these ligametns hold the base of uterus and vagina to lateral walls of pelvis

isthmus
cervix

Front 43

part of wall of uterus
- thickest part
- muscular layer- smooth muscle
