Cell Types of the Ovarian Cortex
-The function of these various cell types will become apparent in the description of folliculogenesis, ovulation, & the luteal phase below.
3) Follicular Cells
4) Theca cells
5) Luteal cells
1) Oogonia: mitotic cells of the ovary (there are no oogonia in the ovary at birth or beyond)
2) Oocytes: meiotic cells, producing daughter cells (4n-1n), w/ unequal distribution of cytoplasm between them.
- 3) Follicular Cells: surround oocyte & create the boundaries of the follicle.
- *cells surrounding the oocyte & lining the follicle internally as it develops are called, Granulosa cells.
- 4) Theca cells: cells on the outer boundary of the follicle derived from the ovarian stroma.
- *Granulosa & theca cells work together in the synthesis of Estrogen.
- 5) Luteal cells: comprise the Corpus Luteum and are derived from follicular cells after ovulation.
- *Makes Progesterone.
