Question

multiple choice question the surface of epithelial tissue that is exposed to the outside or exposed internally to open space is called the ______ o apical surface o lateral surface o basement membrane o basal surface

Explanation:

To solve this, we recall the structure of epithelial tissue. The apical surface of epithelial tissue is defined as the surface that is exposed to the outside or to an internal open space (like the lumen of a tube). The lateral surface is between adjacent cells, the basal surface is attached to the basement membrane, and the basement membrane is a structure the basal surface attaches to, not a surface of the epithelial cells exposed to open space.

Answer:

A. apical surface
