PP2.H2.6 +D1 Primordial and Primary Ovarian Follicles
The Primordial and Primary Ovarian Follicles:
At birth, the ovary contains primordial follicles
These can be described as small follicles with an oocyte surrounded by a single layer of squamous follicular cells
Some primordial follicles begin to develop further from soon after birth
Follicles which show signs of an increase in size of the oocyte and are surrounded by a single layer of cuboidal or columnar follicular cells are described as primary follicles
