Résumé
This book describes Skin cell, Functions, Diseases, Diagnosis and Treatment and Related DiseasesThe human skin is the biggest organ (15% total body weight) of the body and has formed the external covering of the body. The skin has multiple layers of ectodermal tissue and protects the underlying muscles, bones, ligaments and internal organs. While nearly all human skin is covered with hair follicles, it can appear hairless.
There are two normal types of skin:1. Hairy - most skin areas are hairy2. Glabrous skin. - Hairless, present in the palms and solesThe skin for the average adult human has a surface area of between 1.5-2.0 square meters (16.1-21.5 sq ft.) with most of it between 2-3mm (0.10 inch) thick. The average square inch (6.5sq.cm) of skin holds:1.650 sweat glands, 2.20 blood vessels, 3.60, 000 melanocytes and4.
More than 1, 000 nerve endings. Life and death of a skin cell:My name is Skin Man the Skin Cell. I was named Skin Man by my friends who feel that Skin Man is the name of a cell from the largest organ of the human body. It has long been known that our skin cell development begins in the dermatome of the very early embryo before the embryo begins to mature into the recognizably human form of a fetus.
The skin is the largest organ of the body with a total area of about 20 square feet. My skin protects us from microbes and the elements, helps regulate body temperature, and permits the sensations of touch, heat, and cold. My Skin has three layers:The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands.
The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue. My skin's color is created by my special cells called melanocytes which produce the pigment melanin. My melanocytes are located in the epidermis. Melanin produced by my melanocytes comes in two types:1. Pheomelanin (red)2. Eumelanin (dark brown to nearly black). Red and brown pigments are in our skin cells. My actual skin color is just going to be a mix of these colors in varying degrees.
Having a higher concentration of these colors means that the melanins are closer together and my skin is darker. There is a difference in skin color in people all around the world. My skin color can give rise to discrimination between people of various skin colors such as so-called white supremacy. Sometimes the absence of my melanocytes result in melanin being produced and an albino is the result -white hair and pale skin.
My Skin cells are constantly being regenerated. I was born in the lower layer of the skin called the dermis, which is supplied with blood vessels and nerve ending. My skin cell migrates upward for about two weeks until it reaches the bottom portion of the epidermis, which is the outermost skin layer. My skin cell spends another two weeks in the epidermis gradually flattening out and moves toward the surface.
There I will die and will be shed. My life span is about 4 weeks but during my life I serve as the first line of defense against dehydration, infection, injuries and temperature extremes. My skin cells can detoxify harmful substances. My unbroken surface also prevents infectious organisms from entering into systemic circulation. I also absorb and use nutrients applied topically. Fingerprints of the skin are unique to my hostOur skin cells of the penis and the breasts are particularly sensitive to touch and kissing due to the nerve endingsMy dermis is waterproof while having holes we call pores.
Sweat is allowed to escape keeping us cool but fat in our skin keeps us warm in winter. TABLE OF CONTENTIntroductionChapter 1 Skin cellChapter 2 FunctionsChapter 3 L...
