Got You Under My Skin Melanin?

The main pigmentation of the color of the skin is melanin. The main causes of chemistry, quantity, character, melanin collection and distribution, which determine the color and color of sugar

Three contributing factors to skin color:

1. Blood circulation
2. Carotene
3. Melanin pigment

Most melanocytes are located on the basal layer of apertures at the Dermal-Epidural Junction.

They are also in the matrix of papilla and hair bulbs. Melanocytes are dendritic cells. Their dendrites touch flexible keratinocytes around them. Melanocytes are yellow, red and brown color synthesis.

Functions of the Pigment System

In humans, skin and hair pigment protect against harmful effects of sunlight; In some humble creatures, the pigment may provide camouflage protection against predators or act as attractive for sex workers.

Histology of Epidermal Pigment Cells

The number of cells in each unit area is similar to the people of all species - that is, the number of skin color pigment cells depends but does not depend on melanin content.

At the age of 40, the number of epidermal melanocytes began to decrease. This damage to clinical, epidermal pigment cells is usually published by a light color described in healthy adult people. Hair bulbs also lose pigment cells. 25% of the gray age of 25 years of age is available in the Caucasians, 66% in 35 years and 90% of the 45 year-olds.

A melanocyte is found in 6 or 7 basal cells per epidermis, and each melanocytosis reaches 36 carotenoids and possibly some langarhan cells. This dendritic association establishes Imperative Melanin Unit as a group of Integrated Keratinocytes, Melanocytes, and Langerhans cells.

Melanocytes Oval and a Smoothie Saipotolosmic Membrane and Round Nucleus. Dendrites stretch outward from the body to the body. Cytoplasm mesosomes are filled. Melanocytes composed of cytoplasm can be converted to another cell cytoplasm, usually carotenosite.

The skin color of different species is determined by the number and size of the melanocytes (for melanin produced by melanocytes and transferring to the surrounding car circles) for a large degree.

Melanin Synthesis (creation)

Human melanocytes are known for 2 types of melanin production:

1. Eumelanin

2. Phaeomelanin

Eumelanin is black or brown and phyomaline red.

The two types of pigment ratio define the color of human hair and skin.

Factors That Stimulate Melanin Formation

Many physical and chemical agents stimulate the formation of the pigment. Because the tiny wave is the epidermal pigment cells that increase the formation of melanin of ultraviolet light. This process can be chemically noted for several days a week. The long wave ultraviolet light quickly transforms the melanin polymer so that it becomes dark (in the immediate dark), the sunlight extends to the pigmented cells.
