Final answer:
Squamous, Transitional, and Cuboidal are the three types of epithelial cells found in urine sediment, each with distinct shapes and roles in the urinary tract.
Step-by-step explanation:
The three types of epithelial cells that are normally found when evaluating urine sediment are Squamous, Transitional, and Cuboidal. These types of cells can be understood through their unique shapes and functions. Squamous cells are flattened and thin, often derived from the urethra or vaginal wall. Transitional cells change in appearance based on the degree of distension of the urinary bladder, being more squamous when the bladder is full and more cuboidal when it is empty. Lastly, cuboidal cells are roughly cube-shaped and line the renal tubules of the kidney where they play a role in filtering blood.
