GENERAL HISTOLOGY

Detailed explanation-1: -Epithelial cells come in different shapes depending on where in the body they’re found. These shapes are called squamous, cuboidal, columnar, and ciliated columnar. Squamous epithelial cells are flat and are usually found lining surfaces that require a smooth flow of fluid, such as your blood vessels.

Detailed explanation-2: -Epithelial cells may be squamous, cuboidal, or columnar in shape and may be arranged in single or multiple layers.

Detailed explanation-3: -Answer and Explanation: The correct choice is C. oval. The term “oval” is not used to classify epithelial tissue.

Detailed explanation-4: -In epithelial layers, cells form shapes (e.g., squamous, cuboidal and columnar) that carry out distinct functions (e.g., protection, mechanical support, selective permeability, and secretion).
