Why is epithelium better suited for protecting the body's external surface than a mucosa consisting of a simple columnar epithelium would be?
The stratified squamous epithelium is composed of several layers. It is thick and well suited for its protective qualities and its surface cells are constantly being replaced. Simple columnar epithelium is just a single layer of closely packed cells. It lines the digestive tract from the stomach to the rectum. Therefore, the latter would not be best suited to protect your outside surface.
What are the attachments of the parietal pericardium of the heart of a fetal pig?
This membrane is connected tot he visceral pericardium that is attached to the surface of the heart.
What is the function of an epithelium that is smooth on its free surface compared to an epithelium with a folded free surface made up of micro-villi?
Secretion is one of epithelium's major functions. However, if there are microvilli, they are used for absorption. Regular epithelium would be in our skin, and epithelium with microvilli would be in the digestive tract.
What multilayered epithelium with cuboidal basal cells and flat cells at its surface would be classified as?
Multiple cell layers whose apical cells are flattened are stratified squamous. These are epithelial cells arranged in layers upon a basal membrane.
What is the name of the epithelium covering the inner surface of the eyelids and the outer surface of the eye?
Conjunctiva

The inner surface of epithelial tissue rests on a?
Basement membrane - which is a thin layer of fibres.

This membrane is connected tot he visceral pericardium that is attached to the surface of the heart.
How can you tell epithelial tissue from other tissue?
Epithelial tissue has a free surface, a basement membrane, and little intercellular material.
What types of cell junctions connect cells within tissues?
The apical surface does not have any cell junctions because it is a free surface exposed to things that are not epithelial cells. The lateral surfaces of an epithelial cell, which face the adjacent cells on either side contain tight junctions, adherens junctions, desmosomes and/or gap junctions. The basal surface of an epithelial cell adhere to extracellular materials like the basement membrane. Hemidesmosomes anchor the epithelium to the basement membrane in the basal surface.
What type of epithelium lines the inner surface of the ureter?
transitional epithelium
What is free surface?
An epithelium always has on surface where the cells are exposed either to the external environment or to an internal passageway or cavity; this surface is called the free surface of the epithelium.

Human epithelium contains a layer of cubed shaped cells. If the length, height, and width of such a cell is one micrometer (μm), what is the surface area of its cell membrane?
6μm2

What type of epithelium tissue would you expect to find covering a surface subject to physical forces?
stratified epithelium
