Study Notes
Hormonal Functions in Lactation
- Prolactin is responsible for stimulating milk production in the acini cells of the breast lobes.
- The milk ejection reflex, or let-down reflex, requires oxytocin, which is secreted by the posterior pituitary gland.
Self-Breast Exam Timing
- The best time to perform a self-breast exam is 5-7 days after menstruation.
Pelvic Anatomy and Function
- The pelvis supports and protects reproductive, urinary, and digestive organs.
- It is a bony ring structure comprised of the true and false pelvis.
- The true pelvis serves as the birth canal, while the false pelvis supports the growing uterus.
Pelvic Division
- False pelvis extends from the symphysis pubis upward.
- True pelvis extends from the symphysis pubis downward.
Pelvic Measurements
- Inlet (Transverse): 11 cm, Cavity: 12 cm, Outlet: 13 cm (in transverse diameter).
- Overall, the transverse diameter is larger than the anteroposterior (AP) diameter in the inlet.
Mechanism of Labor
- The baby must rotate when passing through the birth canal.
- Fetal positions include Right Anterior (RA), Right Posterior (RP), Left Anterior (LA), and Left Posterior (LP).
Fetal Positioning
- Common fetal positions include:
- Left Occiput Anterior (LOA): Most common and optimal for birth.
- Occiput Anterior (OA): Fetus faced down.
- Occiput Posterior (OP): Fetus faced up.
Male and Female Homologous Structures
- Male and female reproductive systems share homologous structures; for example:
- Glans penis (male) corresponds to the clitoris (female).
- Scrotum (male) corresponds to the labia majora (female).
- Testosterone (male) is parallel to estrogen and progesterone (female).
Pregnancy Considerations
- Recommended to plan pregnancies when women are 20-30 years old and ideally 1 year after marriage.
- Pregnancy spacing should ideally be 3-5 years with a preferable total of 2-3 children.
Medications in Labor
- Oxytoxic medications are used to induce or enhance uterine contractions during labor.
- Tocolytics are used to relax the uterus and suppress premature labor.
Tanner’s Sexual Development
- Secondary sex characteristics in females follow a specific order:
- Acceleration in linear growth, broadening of hips, breast development, followed by the growth of pubic and axillary hair.
Menstrual Cycle Regulation
- The hypothalamus releases Gonadotropic Releasing Hormone (GnRH), which stimulates the anterior pituitary gland.
- The anterior pituitary produces Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH), crucial for regulating the menstrual cycle and ovary hormone production.
Ovarian Function and Menstrual Cycle
- Follicle Stimulating Hormone (FSH) prompts ovarian follicles to mature, while estrogen affects the uterus by stimulating preparations for potential pregnancy.
