Female Reproductive Flashcards
What’s a major difference of the organisation in male and female reproductive tract?
The female reproductive system is internal whereas the male reproductive system is external
The internal reproductive tract includes ovaries, explain what and how these look and do?
Paired ovaries lie within the pelvis
These are the gonads of the female reproductive tract and are responsible for ensuring an ovum is prepared for fertilisation every month
They are attached by mesentary to the uterus
What functions with the ovaries?
A pair of Fallopian tubes which originate from the uterus
Where does fertilisation of the ovum occur?
In the distal regions of the Fallopian tubes (sperm deposited in the vagina travel to the distal regions )
Explain the uterus ? Pt1
It contains 2 important regions: the innermost lining is the endometrium (which is what you get rid of every month on your period) it also undergoes cyclical changes to ensure that a fertilised egg has an initial location for development before a placenta is formed
Explain the uterus pt2?
The uterus contains smooth Muscle called myometrium. Activity in this muscle expels the fetus at the end of pregnancy
What’s the cervix?
The start of the birth canal. It’s linked to the vagina and allows the sperm to deposit during sexual intercourse. Forms a birth canal during childbirth
What is another difference in males and female production of gonads?
Sperm is produced continually whereas egg or ovum is produced cyclical (monthly)
Sperm production is from puberty to death, in females eggs are produced until menopause.
Ova are produced by stem cells called what?
Stem cells called oogonia (diploid.)The ovary at birth will contain all the ova a woman will ever posses.
What process do the oogonia begin?
Meiosis. By birth this results in primordial follicles, consisting of an ova surrounded by a layer of follicle cells.
Oogonia multiply and undergo meiosis but stop at prophase 1
