Structure of the Ovaries
The ovaries consist of three main layers: the outer cortex, the inner medulla, and the ovarian surface epithelium. Within the cortex of the ovaries, there are structures called follicles, which contain the developing egg cells or ova.Functions of the Ovaries
1. Production of Ova: Ovaries are responsible for the production and release of ova, or egg cells, during the menstrual cycle. This process is known as ovulation. 2. Secretion of Hormones: The ovaries produce and release hormones, including estrogen and progesterone, which play key roles in regulating the menstrual cycle, maintaining pregnancy, and influencing secondary sexual characteristics. 3. Reproductive Development: Ovaries are essential for the development and maturation of the female reproductive system, including the uterus, fallopian tubes, and breasts.Study Guide for Ovaries
