Female Reproductive Tract

Question 1

Uterine Horns

Answer 1

The place the embryo develops in the female

Question 2

Ovaries

Answer 2

Part of the female reproductive tract that produces ova and female sex hormones

Question 3

Oviduct

Answer 3

Place where sperm and egg meet and fertilize

Question 4

Uterus

Answer 4

Place where embryo attaches and develops

Question 5

Cervix

Answer 5

Lots of connective tissue; passage between the uterus and vagina

Question 6

Vagina

Answer 6

Female organ of copulation and birth canal; place where sperm is deposited and site of urination

Question 7

Vulva

Answer 7

Exterior genitalia that leads to the vagina; includes left and right labia

Question 8

Infundibulum

Answer 8

Thin membranous tissue that wraps around the ovary to catch the release ovum from the ovary

Question 9

Polyestrous

Answer 9

Female continues to stay in estrous cycle until it becomes bred

Question 10

Seasonally Polestrous

Answer 10

Female stays in estrous cycle only during certain times of the year

Question 11

4 Phases of Estrous

Answer 11

Proestrus
Estrus
Metaestrus
Diestrus

Question 12

What happens during Proestrus

Answer 12

3 days before heat
Prostaglandin is released into the bloodstream by the uterus
More Lutenizing Hormone and Follicle Stimulating Hormones are produced
The follicle releases more estrogen
Estrogen is responsible for behavioral changes before heat

Question 13

What happens during Estrous

Answer 13

8-48 hours 
Egg is released 10-14 hours after onset of estrus 
Ovulation occurs on day 1 
Animal is possibly fertilized then 
Follicle collapses

Question 14

What happens during Metestrus

Answer 14

After ovulation
lasts 3-4 days
Estrogen declines
A Corpus Luteum is created and produces progesterone
Progesterone stimulates uterus to prepare for embryo

Question 15

What happens during Diestrus (if pregnant)

Answer 15

Embryo moves into the uterus and implants
Progesterone is produced in large amounts to stimulate growth in lining of the uterus
Corpus luteum will not regress

Question 16

What happens during Diestrus (if open)

Answer 16

Lasts 12-15 days

Uterus will release prostaglandin and animal will renter proestrus

Question 17

Estrous

Answer 17

The entire cycle that occurs between when the animal goes into heat and ovulation

Question 18

Estrus

Answer 18

Period of standing heat. Female is sexually receptive to male

Question 19

Ovulation

Answer 19

When egg is released from the follicle to be fertilized

Question 20

Luteolysis

Answer 20

Dying of Corpus Luteum

Question 21

Foliculogenesis

Answer 21

The process where immature follicles develop into mature follicles

Question 22

Gravid Uterus

Answer 22

Uterus is caring something

Pregnant

Question 23

Hormone

Answer 23

Chemical messenger that travels to specific organs and prompts a specific response from the organ

Question 24

Cervix

Answer 24

Forms tight barrier to keep out bacteria
Lubricates for sperm transmission
Flush of fetus

Question 25

4 parts of the Oviduct

Answer 25

Infundibulum
Ampulla
Isthmus
Uterotubal Junction

Question 26

Infundibulum

Answer 26

“Catcher’s mitt”

Surrounds ovary, catches ovulated egg, put in oviduct

Question 27

Ampulla

Answer 27

Moves sperm and egg through duct

Question 28

Isthmus

Answer 28

Joins with ampulla to the uterine horn

Question 29

Uterotubal junction

Answer 29

Joins the oviduct to the uterine horn

Question 30

Functions of the Uterus

Answer 30

Sperm transport
Control follicle growth cycles
house and grow embryo
Expulsion of fetus

Question 31

4 Important hormones

Answer 31

Estrogen
Progesterone
Follicle stimulating hormone
Luteinizing hormone

Question 32

Estrogen

Answer 32

Produced by: Ovary (follicle)

Function : regulate reproductive cycle and behavior during estrus

Question 33

Progesterone

Answer 33

Produced by : Ovary (Corpus Luteum)

Function : maintain pregnancy

Question 34

Follicle Stimulating hormone (FSH)

Answer 34

Produced by : Anterior Pituitary in brain

Function : Follicular growth in ovary

Question 35

Luteinizing Hormone (LH)

Answer 35

Produced by : Anterior Pituitary in brain

Function : Cause ovulation, stimulate CL (follicle stage) to secrete progesterone

Question 36

Estrous Cycle - Phases and stages and when they happen

Answer 36

1. Follicular Phase
   - Proestrus stage
   - Estrus stage
2. Luteal Phase
   - Diestrus stage
   - Metestrus stage

Question 37

Functions of the ovary

Answer 37

Storage site of immature follicles
Produce oocyte
Produce hormones (Estrogen and Progesterone)

Question 38

Foliculogenesis

Answer 38

Process where immature follicles develop into mature follicles
