The urethra takes the urine from the urinary bladder to outside of the body.

It is occasionally afflicited by tumours.

Anatomy

  • Proximal portion = urothelium.
  • Distal portion = squamous.

Males

  • Pre-prostatic urethra - transitional epithelium.
  • Prostatic urethra - transitional epithelium.
  • Membranous urethra (from apex of prostate to bulb of penis (bulb of the corpus spongiosusm)) - pseudostratified columnar epithelium.
  • Spongy urethra - pseudostratified columnar epithelium (proximal) & stratified squamous (distal).
