What type of tissue lines the esophagus and forms the skin epidermis?

Stratified squamous epithelial cells are what form the top two layers of the epidermis: stratum corneum and stratum lucidum. Then stratified cuboidal epithelial cells are found in the bottom three layers of the epidermis: stratum granulosum, stratum spinosum, and stratum basale. (Stratum basale is only layer that contains nothing but mitotic cells. This layer contains melanocytes as well.) The entire epidermis, however is identified as stratified squamous because epithelial tissue is always identified by the type of epithelial tissue at the apical (top) surface.


Why is the esophagus lined with stratified squamous epithelium as opposed to simple columnar epithelium?

stratified squamous has many layers of cells; more mature cells at the top and younger cells near the base. it is seen in lumen's and organs that have high abrasion rates. the esophagus moves food bolus from the mouth to the stomach, the 'abrasion' caused by the food passing down through the stomach causes rubbing of the lining which removes cells. thus the esophagus needs many layers of cells so that it can withstand this abrasion and make more cells to replace those lost. note though, that the esopagus at the bottom 3rd (usually past the diaphragm layer) is made of tall columnar cells to deal with the refluxing stomach acid. Barretts esophagus is a premalignant condition where this epithelia spreads further up the esophagus and causes much pain to the person!!


What type of tissue makes up the epidermis?

The outer layer of the skin (epidermis) is made up of stratified squamous epithelium. If it helps, remember stratified squamous is made up of multiple layers to provide protection, like when you scrape your knee. because hopefully, there will be other layers underneath! The epidermis is composed of five layers (from the outer most layer to the deepest layer): Stratum corneum Stratum lucidum Stratum granulosum Stratum spinosum Stratum basale Stratified squamous epithelial tissue The type of tissue that makes up the cells on top and bottom of the leaf (epidermis) is dermal tissue. Epithelial tissue makes up the human epidermis.

If you take tablets and then are sick will the tablets take effect?

Yes, you almost never vomit everything in your stomach, but only the very uppermost liquids. Tablets usually sink to the bottom and are dissolved properly.


How and why are the oceans stratified by density?

a stratification is a term generally used for layering of sediments. Thus a "stratified" ocean is one in which a layer of sediments accumulate at the bottom of the ocean and over time, sediment infill from the continents fill up small local areas around the points where fresh water meets saline ocean water. These areas fill with so much sediments, eventually they become stratified with sediment layers and dry up.


Why is a sedimentary rock called stratified rock?

It most likely means that each layer of the stratificaton represents a time of flood, when a large layer of fresh silt was washed into the body of water, settling to the bottom over pre-existing layers.
