The lumen of the urethra is lined by a transitional epithelium (urothelium) but for the external penile urethral orifice, where it is lined by stratified squamous epithelium (Figure 38). The lamina propria contains loose connective tissue that decussates with striated muscle.
Then, what types of epithelium lines the urethra and where in the urethra are they located?
In general, urothelium lines the prostatic urethra, pseudostratified columnar epithelium lines the membranous segment and most of the penile urethra, and nonkeratinized stratified squamous epithelium lines the fossa navicularis and external urethral orifice.
Where is transitional epithelium found in the urinary system?
This epithelium is found lining the urinary bladder, ureters and urethra, as well as in the ducts of the prostrate gland.
