Endometrium
And sub layers
Inner layer
Highly vascularized
Two layers

- stratum basalis
Stratum functionalis of the endometrium
Closer to the cavity
Shed during menstruation

• internal os- opens to the uterus

Oogenesis
Oogonia
Primary oocyte
Secondary oocyte
Oogonia (2n)
Before a girl is born germ cells differentiate into Oogonia
Some differentiate into primary oocytes
Primary oocyte (2n)
Starts meiosis 1 but does not complete
At puberty anterior pituitary secretes FSH to stimulate maturation of follicles
The primary oocyte completes meiosis 1 to produce secondary oocyte and polar body
Secondary oocyte (1n)
Starts meiosis 2 and then stops
Secondary oocyte with no ovulation
Oocyte dies
