Study Notes

Genito-Urinary System

  • Composed of two systems: Urinary and Genital
  • Urinary System
    • Composed of: Kidney, Ureter, Urinary Bladder, Urethra
    • Kidney
      • Responsible for blood filtration and urine formation
      • Structure
        • Stroma: Capsule
        • Parenchyma: Nephron
          • Formed of: Renal corpuscle, Proximal convoluted tubule (PCT), Loop of Henle, Distal convoluted tubule (DCT)
            • Renal Corpuscle:
              • Bowman's capsule: Cup-shaped capsule, lined by simple squamous epithelium
              • Glomerulus: Tuft of capillaries
            • PCT & DCT: Lined by simple cubical epithelium
            • Loop of Henle:
              • Thick part: Lined by simple cubical epithelium
              • Thin part: Lined by simple squamous epithelium

Male Genital System

  • Formed of: Primary sex organs (Testis), Accessory sex organs (Excretory tubules of the testis, Glands: Seminal vesicle, Prostate, Penis)
  • Prostate Gland
    • Male accessory gland, pierced by the urethra
    • Structure:
      • Stroma: Capsule, trabeculae
      • Parenchyma: Formed of prostatic acini
        • Mucosal acini: Smallest type, in periurethral tissue
        • Submucosal acini: Larger, outer to mucosal acini
        • Main acini: Largest, most peripheral
    • Function: Produces secretion that nourishes sperm

Female Genital System

  • Formed of: Primary sex organ (Ovary), Accessory sex organs (Fallopian tubes, Vagina)
  • Uterus
    • Formed of 3 parts: Fundus, Body, Cervix
    • Wall of Uterus: 3 Layers
      • A. Endometrium:
        • Histologically: Simple columnar ciliated epithelium, Lamina propria, endometrial glands
        • Functionally: Two zones
          • Superficial: Shed during menstruation
          • Deep (basal): Regenerates endometrium
      • B. Myometrium: 3 layers of smooth muscle (inner, middle, outer)
      • C. Perimetrium (serosa): Loose connective tissue
