What are these 'follicles'? They are the oocytes and the cells surrounding them in the ovary. Drag the labels into position as you review follicle development.
|
Oocytes are the resting, immature egg cells
which develops a clear protective layer, the zona
pellucida
surrounded by granulosa cells
a new layer of protective cells, the thecal cells, are
stimulated by LH to produce
androgens and
help attract blood
vessels to support the developing follicle.
the granulosa cells convert the
androgens to estrogen. They also develop
many FSH
receptors.
when stimulated by FSH, the follicle enlarges around
the
oocyte
