What are the four functions of FEMALE REPRODUCTIVE SYSTEM?
|
1. produce eggs
2. deliver eggs to site of fertilization. 3. provide for fetal dev't 4. give birth |
|
|
What are the four parts of anatomy in the female rep sys?
|
1. Ovaries
2. Uterine Tubes 3. Uterus 4. Vagina are teh four parts of this |
|
|
What are the two major partos of OVARIES?
|
1. medulla
2. cortex ...are the two part of this. |
|
|
Where does the action happen in the ovaries?
|
More of this happens in the cortex of the ovaries.
|
|
|
What does the medulla contain? (3)
|
arteries, veins, nerves
are contained within this part of the ovaries. |
|
|
Thru what doe blood vessels and nerves go in the ovaries?
|
These pass thru SUSPENSORY LIGAMENT in ovaries.
|
|
|
What part of the ovaries do eggs develop?
|
These develop in the CORTEX of the ovaries.
|
|
|
Where do eggs develop specifically?
Descibe them. |
These develop in the follicle, fluid-filled bubble-like sacs.
|
|
|
When are mature eggs released?
How? |
These are released during ovulation.
Follicle ruptures to release egg |
|
|
What are two other names for UTERINE TUBES?
|
These are also called oviduct or fallopian tubes.
|
|
|
How long are uterine tubes?
|
These are about 10 cm long (4 in.)
|
|
|
What does uterine tube look like near ovary? What's it called
|
This expands into funnel-shaped INFUNDIBULUM.
|
|
|
What does the infundibulum have?
|
This has finger-like FIMBRIAE that hang over ovary.
|
|
|
What are the FIMBRIAE lined with?
|
These are lined with CILIATED EPITHELIUM.
|
|
|
What muscle is in the uterine tube?
|
Smooth muscle lines these tubes.
|
|
|
What moves egg from ovary to uterus? (2)
|
1. smooth muscle contraction
2. beating of cilia move the egg from here to uterus. |
|
|
What are the walls of uterus like?
|
Thick, very muscular
|
|
|
How big is the UTERUS?
|
This is about 7 x 4 cm (not pregnant)
|
|
|
What are the three parts of the uterus?
|
1. Fundus
2. body 3. cervix |
|
|
What are the three parts of the uterine wall?
|
1. perimetrium
2. myometrium 3. endometrium |
|
|
Where do many complications occur in Female Rep Sys?
|
Uterine may cause these.
|
|
|
What is the perimetrium?
|
Outer serosa layer.
|
|
|
What layer of uterine walls are very responsive to hormones?
|
The myometrium are very responsive to these.
|
|
|
What layer produces labor contractions?
What control them? |
The myometrium creates these contractions which are under hormonal control.
|
|
|
What is endometrium?
|
This layer is MUCOSAL EPITHELIUM.
|
|
|
What is mostly lost during mentruation?
|
The superficial part of the endometrium is mostly lost at this time.
|
|
|
Where does the embryo implant?
|
This implants in the endometrium.
|
|
|
What important part of fetal dev't does the endometrium produce?
|
This layer forms part of the placenta.
|
|
|
What is the birth canal?
How big is it? |
The vagina.
8-10cm long |
|
|
What's egg production called?
|
This is called Oogenesis.
|
|
|
What are eggs in terms of chromosomes?
|
These are haploid (1N) cells.
|
|
|
What cell division produces eggs? From what?
|
These are produced from a diploid cell by meiosis.
|
|
|
When does OOGENESIS begin?
|
before birth this begins.
|
|
|
How many 2N form before birth?
What are they called? |
About 6-7 million OOGONIA (2N) form at this time.
|
|
|
What do some OOGONIA differentiate into?
|
Some of these differentiate into primary oocytes.
|
|
|
After birth, how many primary oocytes remain?
What's it called when the rest have died? |
About 2 million of these remain after birth.
Rest have died, called ATRESIA. |
|
|
After puberty about how many primary ooctyes remain?
|
400,000 of these will remain after puberty.
|
|
|
After puberty, what stimulates primary oocytes to undergo meiosis I?
|
FSH
|
|
|
What does Meoisis I produce? (2) What are they?
|
1. polar body - tiny cell that dies
2. secondary oocyte - 1N cell |
|
|
If a secondary oocyte is not fertilized what happens? what doesn't happen?
|
never finishes meiosis II and dies.
