The cell is now called a primary oocyte. It is contained within a
structure known as the follicle inside of the ovary. The cells that
comprise the follicle will support and nurture the developing egg.
During ovulation, generally a single follicle in one ovary ruptures, and the secondary oocyte and a few follicle cells are released into the Fallopian tube. Most of the follicle cells, however, remain in the ovary and form a transient endocrine structure called the corpus luteum.

Which numbered structure below indicates a Fallopian tube?
Why does oogenesis involve two asymmetrical divisions that ultimately result in a large ovum that receives most of the cytoplasm and smaller polar bodies that receive almost no cytoplasm?
Hormones regulate the timing of both the ovarian and menstrual cycles. It is essential that these two cycles be linked so that the uterus is prepared to receive and nurture the embryo if fertilization does occur. Which of the following events marks the first day of the menstrual cycle?
High levels of estrogen trigger the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary. What is the effect of the LH surge?
