    Study Notes

    The Human Reproductive System

    • Reproductive organs are called genitalia, divided into primary genitalia (gonads that produce gametes) and secondary genitalia (other structures that aid in the reproductive process)

    Female Anatomy

    • Primary genitalia: ovaries
    • Secondary genitalia: fallopian tubes, uterus, vagina, and external genitalia (vulva)
    • Ovaries: paired structures located on either side of the uterus, divided into cortex (contains eggs) and medulla (contains blood vessels, nerves, and lymphatic tissue)
    • Fallopian tubes: passageway for the egg to get to the uterus, begin as a large funnel, surrounded by ciliated projections called fimbria, leading to a widened area, followed by a longer, narrower portion
    • Uterus: located in the pelvic cavity, posterior and superior to the urinary bladder, and anterior to the rectum
    • Cervix: valve-like portion of the uterus that protrudes into the vagina
    • Layers of the uterine walls: perimetrium (outermost layer), myometrium (smooth muscle), and endometrium (inner lining of epithelium and secretory cells, highly vascularized, made of two layers: basal layer and functional layer)
    • Vagina: tube running from the uterus to the outside of the body, receives the penis during intercourse and allows for the passage of menstrual fluid out of the uterus
    • Hymen: perforated membrane that may cover the external opening of the vagina

    Reproductive Physiology: Female

    • Menstrual cycle: takes about 28 days, involves the ovaries and uterus, and is hormonally regulated
    • Ovarian cycle: monthly maturation and release of eggs from the ovary
    • Uterine cycle: monthly buildup, decaying, and shedding of the uterine lining
    • Goal of the cycles: release an egg for fertilization, prepare the uterus to receive the fertilized egg, and nourish the fertilized egg should pregnancy result

    Menses and Menstruation

    • Menstrual cycle begins with the first day of menses
    • Menstruation: term referring to the actual shedding of the endometrium, the “period” itself
    • Menses: time during which a woman is menstruating, usually lasts 4-5 days but can be longer or shorter in different women

    Male Anatomy

    • Primary genitalia: testes, producing the male gamete, sperm
    • Secondary genitalia: penis (sperm delivery organ), epididymis, vas deferens, urethra (sperm ducts), and several accessory glands including the prostate gland, seminal vesicles, and bulbourethral glands
    • Testes: paired organs suspended in a sac called the scrotum, hanging on either side of the penis
    • Epididymis: first stop for sperm after leaving the testes, sperm spend about 2 weeks maturing and gaining the ability to swim
    • Vas deferens: muscular tube that propels sperm during ejaculation
    • Accessory glands:
      • Seminal vesicles: add sugar and chemicals to the sperm
      • Prostate gland: adds fluid to liquefy the semen and protect the sperm from the acid environment of the vagina by secreting an alkaline substance
      • Bulbourethral glands: add mucus to the semen

    Male Reproductive Physiology

    • Sperm production: continuous process beginning at puberty and continuing until death
    • Spermatogenesis: process by which immature cells become mature sperm, occurs in the seminiferous tubules of the testes
    • Sperm then travel from the seminiferous tubules to the epididymis where they mature and gain the ability to swim
