Study Notes
Gonads: Ovaries and Testes
- Gonadal primordia develop into testes if a Y chromosome and TDF gene are present.
- Gonadal primordia develop into ovaries if no Y chromosome and TDF gene are present.
Male and Female Duct Systems
- If testosterone is present, the Wolffian duct system develops into the male duct system.
- If testosterone is absent, the Mullerian duct system develops into the female duct system.
Female Reproductive System
- The female reproductive system includes the uterus, fallopian tubes, ovaries, cervix, and vagina.
- Diagrams of the female reproductive system and detailed labels were included in the slide.
Ovum Maturation
- The process of ovum maturation was presented in the slide but no further details.
Menstruation
- The menstrual cycle consists of four phases: egg maturing (follicular phase), ovulation, preparation for fertilization (luteal phase), and menstruation (uterine shedding).
- Diagrams and explanations were provided for all four phases.
Ovarian Cycle
- The ovarian cycle describes follicular development, menstruation, ovulation, and luteal phases.
- Associated pituitary hormones and fluctuating hormone levels (FSH & LH) were shown graphically.
- The endometrial cycle is also depicted.
Uterine Cycle
- The uterine cycle is described as having three phases.
- The menstruation phase is the breakdown of the endometrium and the release of blood.
- The proliferative phase is the formation of a new endometrium under estrogen influence.
- The secretory phase is impacted by progesterone.
- Hormonal levels (estrogen, progesterone, FSH, LH) are depicted graphically throughout the cycle.
- Basal body temperature is tracked as an indicator throughout the cycle.
The Zygote
- Successful fertilization takes place in the oviduct.
- Successful implantation occurs in the uterus.
- The zygote embeds itself in the endometrium wall.
No Zygote, No Pregnancy
- If no fertilized ovum arrives in the uterus, the endometrium breaks down causing bleeding.
Twins
- Usually, one ovum is released per month from alternating ovaries.
- Dizygotic (fraternal) twins result from the release and fertilization of two ova.
- Monozygotic (identical) twins develop from a single fertilized ovum that splits.
Male Reproductive System
- Testes are the male reproductive organs.
Testes
- The testes are divided into interstitial cells of Leydig (testosterone production) and seminiferous tubules (spermatogenesis).
