Question

Explain how one would differentiate tissue that was pseudostratified, stratified, or simple. Give an example of each type of tissue. While Dr Wentz-Hunter was in Canada over spring break, she decided to go on ice river tour of Jackson Canyon. During the tour, she was separated from her group and became lost. At first she was not worried but then the sun set and she had not found her way back to the lodge. As a result she was forced to spend the night in the canyon. A) Describe the process that Dr Wentz-Hunter's body would go through to prevent hypothermia. Be very specific. B) If Dr Wentz has food and water with her, are her chances of avoiding hypothermia better or worse? Why? C) She noticed some Canadian Geese were near her during the night and did not seem to be having any problems with the temperature. In fact, some were standing in the water of a nearby river. Explain the processes of thermoregulation in this animal that may allow them to stand in near freezing water. D) Would you expect Dr Wentz to be able to stand in the water without effect? Why or why not?

Answer 1

1)A pseudostratified epithelium is basically defined as a type of epithelium which comprises only of a single layer of cells.It usually has the cell nuclei which is positioned in a way that suggestive of stratified epithelia.

Example it is present in the linings of the trachea

A stratified squamous epithelium tissue usually consists of the various epithelial cells which are arranged in layers .They usually act upon a cutaneous membrane. The big difference is that only one layer is present in contact with the basement membrane .On the other hand the various other layers usually end up adhering to one another .This is done to maintain structural integrity .example:They are present in skin

A normal and a simple tissue consists of a group of cells that have a similar origin and they are similar in structure and function .examples tissued in various body parts tissue.
