The wall of the urethra consists of mucosa with variable epithelium. The bladder neck and prostatic urethra contain transitional epithelium, the spongy urethra is covered with stratified columnar epithelium, and the fossa navicularis is covered with squamous epithelium, which is designed to withstand the stresses of abrasion.
