  1. Transitional Epithelium (Urothelium)
    1. Lines the lower urinary tract (Bladder and proximal Urethra) as well as the upper tract (ureters and Kidneys)
      1. Distal Urethra is instead lined by stratified squamous epithelium
    2. Barrier to urinary tract toxins
    3. Multilayer cuboid Cell Structure allows the epithelium to expand and contract
    4. Disrupted by Trauma, infection, inflammation or obstruction
  2. Lamina propria (submucosa)
    1. Lies deep to the epithelium of the Urethra and Bladder
    2. Contains neurovacular structures, including Urethra and Bladder innervation
  3. Muscularis Propria (Detrusor Muscle)
