Question

Quizplus · Accepted Answer

Transitional epithelium is a specialized type of epithelium found in the urinary tract that is able to stretch and expand as the bladder fills with urine. Its unique structure allows for increased flexibility and distensibility without compromising the barrier function of the bladder wall. Simple squamous epithelium and pseudostratified epithelium are not found in the urinary tract, while stratified squamous epithelium is found in the skin and lining of the oral cavity and esophagus. Sphincters are not mucosal specialized cells, but has a contractile function to regulate the passage of urine.
