| The Secondary Follicle | ||||
Before moving on, go to anatomy of the mature secondary follicle. |
 This
section of the ovary shows the relative size (box) of the enlarged area
to the left as compared with the mature (Graafian) follicle (arrows) seen
in the center of the section. Note the difference in the size of the antrum
(A) between the early secondary follicle (enlarged at the left) and the
mature secondary (Graafian) follicle (arrows) as seen above. You should
have a closer look at the anatomy of the mature secondary
follicle. |

| The Corpus Luteum | ||||
 |
 The
above section of the ovary shows the relative size (box) of the enlarged
area to the left as compared with the mature (Graafian) follicle (arrows)
seen in the center of the section. The corpus luteum is the enlarged remnant
of the secondary (Graafian) follicle following ovulation (the release of
the oocyte). Note the vacuolization (white circles) associated with the
production of lipid soluable steroid hormones (progesterone and estrogens). |

This
section of the ovary shows the relative size (box) of the enlarged area
to the left as compared with the mature (Graafian) follicle seen in the
center of the section. On the left, two primary follicles are seen. The
oocytes (Oo) are surrounded by a single layer of follicular cells at this
stage (arrows).
