Pharynx Histology â Epithelial Lining of the Pharynx Epithelial Lining of the Pharynx (introduction to pharynx histology) The surface of the nasopharynx is covered by the same pseudostratified columnar epithelium that is found in the nasal cavity.
Simple squamous epithelium. This type is composed of a single layer of flattened, scale-or plate-like cells. It is quite common in the body. The large body cavities and heart, blood vessels and lymph vessels are typically lined by a simple squamous epithelium.pithelia are avascular, but all epithelia grow on an underlying layer of vascular connective tissue. The connective tissue and the epithelium are separated by a basement membrane. Epithelium covers all free surfaces of the body. Epithelium also lines the large internal body cavities, where it is termed mesothelium.
