Ovaries
Detailed study of the primary female sex organs, including their structure, location, and functions in gamete and hormone production.
What is Ovaries?
The process of the formation and development of female gametes (ova).
Key points
- Identify the location and structure of the ovaries.
- Describe the histological divisions of the ovary (cortex and medulla).
- Explain the process of oogenesis and the role of ovarian follicles.
- List the major hormones produced by the ovaries and their functions.
Common exam trap
Confusing the cortex and medulla regions.
Definitions
- Term
Oogenesis
- Meaning
The process of the formation and development of female gametes (ova).
- Term
Ovarian Follicle
- Meaning
A structure within the ovary that contains an immature oocyte and surrounding cells, which nourish and protect the oocyte and play a role in hormone production.
- Term
Corpus Luteum
- Meaning
A temporary endocrine structure formed in the ovary after ovulation from the remnants of the ovarian follicle, primarily producing progesterone.
- Term
Estrogen
- Meaning
A group of steroid hormones produced by the ovaries, responsible for the development and regulation of the female reproductive system and secondary sex characteristics.
- Term
Progesterone
- Meaning
A steroid hormone produced by the corpus luteum and placenta, essential for the menstrual cycle, pregnancy, and embryogenesis.
