Epithelial tissue is one of the four main types of tissue found in the human body. There are seven types of epithelial tissue, simple squamous, simple stratified, cuboidal squamous, cuboidal stratified, columnar simple, columnar stratified, and pseudostratified. Simple epithelium contains a single layer of cells, stratified epithelium contains multiple layers of cells. Pseudostratified epithelium appears to be stratified but is not, it is a single layer of cells that contains nuclei that arranged to make the tissue stratified. The three shapes of epithelial are cuboidal, columnar and squamous. Cuboidal is shaped like cubes or dice. Columnar is shaped like bricks, and squamous is shaped like flat tiles.
Simple epithelium consists of a single layer of epithelial cells, this tissue lines body cavities and tracts, the surface of this tissue is exposed to fluid or air and the bottom is attached to the basement membrane. Stratified epithelium consists of layers of stratified cells. This type of tissue typically covers the outside of the body, it makes up the skin. It is also found in portions of the digestive tract and reproductive tract. Epithelial tissue covers the outside of the body and lines organs, blood vessels, lymph vessels, and cavities. The functions of epithelial tissue cells is to absorb, secrete, and excrete substances. Epithelial tissue in the glands secretes hormones, enzymes, and other substances. In the intestines, this function is to absorb nutrients during digestion. This tissue function in the kidneys is to excrete wastes, and excrete perspiration in sweat glands. Epithelial tissue protects against microorganisms.
Eczema, which is also known as dermatitis, is a disease that causes inflammation and irritation of the skin. Dermatitis means derma which means skin and -itis means inflammation. It affects the stratified squamous epithelium of the skin and the underlying blood vessels. Eczema is an inflammation of the skin, it is caused by allergies, changes in hormone levels, stress, and genetic disease. As of right now, there are no cures for eczema but there are ways to treat it. You can treat eczema with ointments, this can help soothe symptoms and medications can help with the dryness and irritation of the skin. Someone who has eczema typically moisturizes the skin to avoid irritation. The treatment of eczema represents a great challenge in the eyes of a dermatologists. The first step in treating it to identify the inflammation and irritation patch of skin on the body. The next step would to use an ointment or medicated salve on the inflamed irritated skin. Medications you can use to treat eczema are steroids, antihistamine, and topical antiseptic. These medications can reduce the inflammation and allergic reaction, while preventing the growth that causes the skin to become infected. There are different ways to treat eczema with just self-care. The first form of self-care is using an ultraviolet light therapy, a barrier cream, PUVA, urea, moisturizer, and coal tar extract. These self-care remedies for treating eczema can soothe the inflamed irritated skin, it can soothe the scaling and itching skin, it can also hydrate the skin.

  1. Epithelial tissue is one of the four basic types of connective tissue and refers to the cells that covers the exterior surface of the body, lines internal cavities and passageways, and forms certain glands. Epithelial tissue cells are organized into one or more layers, arranging everything into separate but connected units. There are seven basic types of epithelium and each type is defined by the number of cell layers, being simple, stratified, or pseudo-stratified along with how those cells are shaped, being squamous, cuboidal or columnar. Simple epithelium and pseudo-stratified epithelium contains a single layer of cells. Stratified epithelium contains two or more layers of cells. Epithelial tissues provide the body’s first line of protection from physical, chemical, and biological wear and tear and each type of tissue accomplishes a different function. The stratified squamous epithelium of the skin can develop eczema, an inflammatory disease that is triggered by allergies and also develops as a response to other types of biochemical stress in the body. There may also be a genetic factor in the development of eczema, but the exact cause of the condition is unknown to this day. The inflamed skin is typically dry and scaly, causing the skin to itch. The condition is incurable, but there are promising treatments that offer relief from the irritation caused by inflammation of the skin. Generally topical creams are applied to the affected area to hydrate the skin, providing relief from itching. Medications along with other forms of self-care can treat the irritation symptoms.
