Note that whether the epithelial layer of the specimen is on the top, bottom, right, or left of the slice varies with how the specimen slice was positioned on the slide. Smooth -Spindle shaped, involuntary, and non-striated. Epithelium is a type of tissue whose main function is to cover and protect body surfaces but can also form ducts and glands or be specialized for secretion, excretion, absorption and lubrication. b.

This question was created from pos wa 8.docx. Apseudostratified epitheliumis really a specialized form of a simple epithelium in which there appears at first glance to be more than one layer of epithelial cells, but a closer inspection reveals that each cell in the layer actually extends to the basolateral surface of the epithelium.

Similarities: All layers are made up of epithelial cells, All layers are tightly packed, There are no blood vessels, All layers but the stratum basale layer contain keratin. A layer of epithelial cells always serves as an outer layer for some structure, but, when looking at a tissue preparation on a slide, do not assume that just because you have found one end of the tissue sample you are automatically looking at epithelial tissue.
