Q

describe the layers of the endometrium and the function of it

A
  • Endometrium supplies nutrients needed for embryonic and fetal development
  • it has two layers :
    -Functional layer that is shed during each menstrual period
    -Basal layer of multiplying cells

Q

What is Endometriosis and what can it cause ?

A
  • It is the presence of tissue resembling endometrium outside the uterus .
  • It causes a chronic inflammatory reaction that may result in the formation of scar tissue

Q

What happens when the egg reaches vesicular follicle ?

Q

How does Oogensis occur ?

A
  • A primary oocyte undergoes meiosis I , they two resulting cells are haploid (n). the secondary oocyte can only go through meiosis II if the egg is fertilized by a sperm cell.
  • If not it will die shortly after being released from the ovary
17
Q

After meiosis I during Oogensis two haploid cells are formed , and one of them is a polar body , what is a polar body ?

A
  • This cells function is to simply hold discarded chromosomes
18
Q

What is Ovulation ?

A
  • This is when the vesicular follicle bursts , releasing the oocyte
19
Q

What happens after the vesicular follicle has burst ?

A
  • It then develops into a corpus luteum
20
Q

What happens to the corpus luteum if the egg is not fertilized

A
  • It disintegrates
21
Q

What occurs in the Follicular phase ?

A
  • FSH promotes the development of primary follicles which primarily secrete estrogen .
  • As estrogen rises , it exerts negative feedback control over anterior pituitary secretion of FSH , ending the follicular phase
  • lastly a surge of LH is released from the anterior pituitary triggering ovulation on day 14 on a 28 day cycle
22
Q

What happens in the luteual phase ?

A
  • LH promotes the development of the corpus luteum , which secretes high levels pf progesterone and some estrogen
23
Q

What is menopause ?

A
  • its when the ovarian cycle ceases
24
Q

What is a uterine cycle ?

A
  • It is a cyclical series of events caused by estrogen and progesterone
25
Q

What occurs during day 1-5 in the 28 day cycle ?

A
  • Menstruation : low levels of estrogen and progesterone cause the endometrium to disintegrate and its blood vessels to rupture
26
Q

What occurs during day 6-13 in the 28 day cycle ?

A
  • Proliferative phase : increased production of estrogen by a new follicle causes the endometrium to thicken and become glandular
27
Q

What occurs during day 14 in the 28 day cycle ?

A
  • Ovulation
28
Q

What occurs during day 15-28 in the 28 day cycle ?

A
  • Secretory phase : increased production of progesterone by the corpus luteum causes the endometrium to thicken.
  • Also causes the uterine glands to mature and produce a thick secretion
