Q

adaptations of the fallopian tube

A

finger like appendages called Fimbria that move the ova into the tube once it has been expelled by the follicle
Cilia cell lining the tube, move the egg cell along

17
Q

what is a follicle

A

one egg cell surrounded by one or more layers of follicle cells

18
Q

function of a follicle

A

protect, support, nourish the developing ova,

19
Q

what hormone dose a follicle produce

A

oestrogen

20
Q

how many follicle release an egg in a women’s lifetime

A

only several hundred follicles release eggs out of around 400,000 follicles which are their from birth

21
Q

what is oogenesis

A

consists of the meiotic cell divisions that lead to the production of ova (eggs) in females
The process begins during fetal development with the fetal ovary. Diploid cells called oogonia divide by mitosis and differentiate to produce primary oocytes (still diploid with 46 chromosomes).

22
Q

what is a corpus lutem

A

the remains of the follicle following ovulation. It remains functional, producing oestrogen, progesterone, and inhibin, until it finally degenerates

23
Q

what do cilia in the FT do

A

move the ova down the tube

24
Q

what hormone causes a follicle to start developing an oocyte

A

Follicle stimulating hormone, (FSH)

25
Q

what hormone triggers ovulation

A

liturgising hormone (LH)

26
Q

what is Gonadotrophin - releasing hormone (GnRH)

A

produced by the Hypothalamus and controls the release of Follicle Stimulating Hormone (FSH) and Luteinising Hormone (LH)

27
Q

function of FSH

A

stimulates the ovaries to grow an ovum

28
Q

function of LH

A

triggers ovulation and the growth of the Corpus Luteum

29
Q

function of oestrogen

A

produced by the ovum and the corpus luteum. This then reduces the amounts of FSH and LH to prevent too many ovum developing. It plays a role in developing the lining of the uterus ready for embryo growth

30
Q

function of progesterone

A

released by the corpus luteum and works to develop the endometrium and stimulates the mammary glands

31
Q

how many phase dose the ovarian cycle have

A

3 the follicle phrase, ovulation, luteal phrase

32
Q

what happens in the follicular phase

A

the development of the follicle, the meiotic stages of division leading to the formation of the secondary oocytes, and the secretion of oestrogen from the follicle

33
Q

when is ovulation and what causes it

A

around day14-15, and is caused by the high levels of LH

34
Q

Explain the luteal phase

A

Day-15-28
Ovum expelled the egg, the follicle collapse and becomes a corpus lutum, this produces Mostly progesterone and a little bit of oestrogen
If egg is not fertilised then the CL collapses, O and P stop
, endometrium collapses which causes bleeding

35
Q

what is a corpus lutum

A

remains of a follicle that has released an egg, it produces hormones during pregnancy

36
Q

where are the follicles located

A

on the cortex of the ovary-

37
Q

Is the fallopian tube fixed

A

No it is mobile which can causes issues if it twists

38
Q

How long is the fallopian tube

A

10cm

39
Q

function and location of fimbria

A

end of fallopian tube

guide the expel ova into the F tube

40
Q

where dose fertilization occur

A

in the Ampulla section of the fallopian tube
