what are the steps in the ovarian cycle?
1.primordial follicles
2. primary follicle
3. secondary follicle
4. tertiary follicle
5. ovulation
6. corpus lutetium

thecal cells
what secretes estrogen in the primary follicle?
granulosa and thecal cells
what is the zona pellucida?
clear region around oocyte
during the secondary follicle, what happens?
wall of follicle becomes thicker
what is the tertiary follicle also called?
Graafian follicle
