tunica albuginea (dense connective tissue)
cortex - containing ovarian follicles in various stages of development.
medulla - occupies central region of ovary, consists of blood vessels and connective tissue.
Which layer has the folicles?
cortex
Primordial follicles
- present before birth
- consists of a primary oocyte arrested in (dictyotene) meiotic prophase I surrounded by a layer of flattened follicular cells.
Outside of follicular cells are ____.
stromal cells
At puberty cyclic secretion of FSH stimulates ___ to develop and produce _____ .
groups of follicles develop and produce estrogen
3 things that happen every 28 days after puperty:

- Their follicular cells acquire more FSH receptors
- these flattened folicular cells become more columnar (now called granulosa cells).
Primary Unilaminar Follicles - consists of _____
a primary oocyte surrounded by one layer of granulosa cells (unilaminar)
Primary Multilaminar Follicles
- consists of a primary oocyte surrounded by more than one (multilaminar) layers of granulosa cells.
