Steps in Hormonal Reproductive Cycle where no pregnancy occurs
- Hypothalamus triggers release of progesterone and estrogen from the ovaries, causing menstruation and the beginning of a new cycle.
- Hypothalamus signals the pituitary gland to release Follicle Stimulating Hormone (FHS) and Luteinizing Hormone (LH).
- Ovarian Follicle releases a mature ovum & corpus luteum releases progesterone.
- If pregnancy does not occur, the corpus luteum shrinks and stops producing progesterone.
- Cycle begins again.
Steps in Hormonal Reproductive Cycle where pregnancy occurs.
After the ovum has been released, if pregnancy occurs:
1. High levels of estrogen and progesterone will prevent further eggs from maturing; prepares breasts for lactation.
2. Towards the end of the pregnancy, pituitary gland releases oxytocin, causing uterine contractions. Ovaries release relaxin, which loosen pelvic ligaments
Three Layers of the Uterus
Endometrium, Myometrium, Perimetrium
Five Orientations of the Uterus
Anteverted
Anteflexed
Mid-position
Retroverted
Retroflexed
Structure of Fallopian Tubes
Infundibulum, Ampulla, isthmus
Uterine Ligaments
Broad
Cardinal
Round
Utero-ovarian
Uterosacral
Structure of Broad Ligament
Thin sheet of peritoneum that connects the uterus and fallopian tubes to the lateral wall of pelvis. Consists of the mesosalpinx, mesovarium and mesometrium.
Bartholin’s glands
Located slightly inferior and on either side of the vaginal introitus; secrete fluid to lubricate the vagina.
Skene’s glands
Located on the anterior wall of the vagina around the lower end of the urethra
Stages of egg on fertilization
Zygote - fertilized egg
Morula
Blastocyst
Embryo
Fetus - all basic germ layers have formed.
