Study Notes
- The female reproductive system consists of gonads and reproductive pathways.
Gonads
- The ovaries are the gonads in the female reproductive system which have an internal and external part.
Reproductive Pathways
- These are the ducts involved in fertilization and pregnancy.
- Fallopian Tubes:
- Two small tubes connect the ovaries to the uterus.
- Ciliated cells inside move to help eggs travel.
- They secrete fluid to ease movement and provide food for the zygote if fertilization occurs before reaching the uterus.
- Fertilization takes place here.
- Uterus:
- It also called the matrix.
- Cone-shaped cavity in the uterine wall connects to the fallopian tubes.
- The wall has a muscle layer and is lined with mucus.
- Pregnancy develops in the uterus.
- Vagina:
- Elastic tube contains glands that secrete lubricants to help with sexual intercourse.
- A small membrane called the hymen is located at the entrance.
- Vulva:
- The external genital organ of the woman.
- Contains the labia majora and minora, including the clitoris, which is made up of cavernous tissue.
- The labia contain the Bartolini glands, which produce lubricant.
Female Gametogenesis: Oogenesis
- Oogenesis differs from spermatogenesis as it is produced discontinuously.
- Oogenesis starts at puberty and ends at menopause.
- Only one egg is produced from each cell where meiosis occurs.
- Typically, one egg is produced each month.
- The menstrual cycle is the result of the coordination of two processes that occur periodically in the ovaries and in the uterus namely, the ovarian and uterine cycles.
Eggs
- Eggs, being gametes, contain 23 chromosomes.
- An ovule is round, measuring 0.1 mm in diameter, and immobile.
- It has reserve substances (yolk).
- Covered by the pellucida and corona radiata, which contain accompanying cells and mucous substances.
