Study Notes
Menstrual Cycle and Hormones
- Estrogen is responsible for causing mucus to be thin, transparent, and highly stretchable.
- The average age of onset for menarche is around 12-13 years old.
- The main event of the follicular phase before ovulation is the growth of follicles in the ovaries.
- The average duration of menstrual flow is 3-7 days.
- The average amount of menstrual flow per period is around 35-50 ml.
- Progesterone is thought to be the cause of premenstrual syndrome (PMS).
- Prolactin stimulates the ductile structures of the breasts.
- Progesterone has a thermogenic effect and increases basal body temperature.
- The primary role of the corpus luteum after ovulation is to produce progesterone to maintain the pregnancy.
- Spinnbarkeit is the stretchy, thread-like quality of cervical mucus, indicating ovulation.
Menstrual Cycle and Pain
- Exercise is the most helpful activity for dysmenorrhea (painful menstrual cramps).
- The signs of ovulation mentioned are a change in cervical mucus (Spinnbarkeit) and a slight increase in basal body temperature.
Hormonal Changes
- Progesterone causes the glands of the uterine endometrium to become corkscrew or twisted in appearance.
- Estrogen promotes the growth of the acini cells of the breasts and causes a tingling sensation and fullness before menstruation.
Fertility and Conception
- The fallopian tube plays a crucial role in the process of conception by facilitating fertilization.
- The occurrence of fertilization depends on the timing of ovulation.
- The key event during the luteal phase of the menstrual cycle is the preparation of the uterus for implantation.
Puberty
- The average age range for menarche is 11-16 years old.
- The primary reproductive organ changes during puberty in boys include the growth of the testes, epididymis, and penis.
- The scientific term for the physiological changes that occur in fertile female humans and apes is menstruation.
This quiz covers the sequential order of pubertal changes in girls and boys, including physical developments such as growth spurts, breast development, penile growth, and onset of menstruation. Test your knowledge of the stages when reproductive organs become functional and the secondary sex changes occur.
