Simple epithelium

A flat 2D histology-style view of simple epithelium as a thin continuous sheet of tightly packed cells arranged in a single layer. The cells are closely joined side by side with very little space between them, forming a smooth exposed apical surface and a contrasting basal side resting on a thin pale basement membrane. Cell outlines are neat and aligned, with polygonal to rectangular, cuboidal, flattened, or mildly columnar profiles depending on the section. Each cell contains a distinct round to oval nucleus, typically aligned in a uniform row. The tissue appears pale pink, beige, or pink-lavender overall, with a smooth cohesive lining appearance.
