What do melanocytes do?
Melanocytes produce melanin which contributes to pigmentation of the skin.
What is hyper- pigmentation?
Hyper-pigmentation , a process of the skin to be darken as compare to its surrounding.Our skin cell melanocytes produce a substance called melanin. melanin is the pigmentating substance in our skin.Cause: Excess of the melanin in the skin causes the hyper-pigmentation of skin.There are many skin condition which is form of hyper-pigmentation in skin. More common reason for such pigmentation disorders is the harmful ultra violet radiation in skin. The inverse of hyper-pigmentation is the depigmentation or hypo-pigmentation such as the skin condition vitiligo.
Which endocrine gland helps regulate the release of gonadotropin and controls body pigmentation?
The pituitary gland helps regulate the release gonadotropins. It also regulates melanocyte-stimulating hormones that produce the melanin for body pigmentation.
How does the epidermis guard against harmful radiation?
Melanin is the dark pigmentation contained in skin. It is contained in melanocytes, which are the cells which produce melanin. The purpose of melanin is to filter out harmful radiation from the sun. Mostly it does not. The best way is to use a sunscreen with SPF of 30 or more.
What controls the activity of melanocytes?
Melanogenisis is the activity that controls melanocytes. Melanocytes are the cells in the human body that produce melanin, the pigmentation found in eyes and skin.
Is there melanin in melanocytes?
Melanocytes produce melanin.
How are people albino due to a lack of enzymes?
Without the proper enzymes, melanin, the pigment responsible for skin color, cannot be produce. Normally, enzymes are made by cells using a gene or genes from the DNA. However, if a person has a mutation so that either they do not produce enough melanin or they cannot properly make melanin, or they cannot manufacture melanin period, or another such problem, the person will be an albino- they will lack pigmentation.
What is hypo-pigmentation in skin?
Pigmentation term use for the process of skin which is responsible for the coloration of skin and continuously produce pigment.Hypo-pigmentation: It is also termed as depigmentation. It is a pigmentation disorder in which white spots appear on skin. Hypo-pigmentation in skin occurs when in a certain part of skin pigmented substance "Melanin" quantity decreases from a certain level.Vitiligo, Nevus depigmentosus , Pityriasis Alba and Idiopathic guttate hypomelanosis are the example of Hypo-pigmentation
Identify the hormone responsible for regulating skin pigmentation?
melatonin is the pigment which increases skin pigmentation. This is produced by melanocyte stimulating harmonemelanocyte-stimulating hormoneMelanin stimulating hormone, or melanocyte stimulating hormone (MSH). It is produced in the pituitary and cause melanocytes to increase production of melanin, the pigment responsible for darkening of the skin.
What cells produce keratin and melanin?
Keratinocytes or squamous cells produce keratin and Melanocytes produce melanin, pigment.
Why do the elderly have gray or white hair?
The colour in our hair comes from a pigment called melanin. In a very basic run down of how it works, as hair is being formed melanin is injected into cells containing kerotin, a protein in our hair. As we age this process slows and eventually stops, causing our hair to gray and eventually whiten.
What is the pigment that colors the skin?
Melanin is the pigment inside skin cells.melanocytes produce melanin of which there are two types; pheomelanin (red) and eumelanin (very dark brown). it can get very complex, but those are the basicsLizzy the guru - the above is correct, but to add a little more, these melanocyte cells have prominent characteristics or traits (known as phenotypes).We understand these traits ensure their responsibility for our skin and hair's pigmentation allowing enough melanin production to provide protection from damage by ultraviolet radiation (sunlight).As we continue to study the role of melanin and pigmentation, it is hoped that skin Biology will lead us to understand skin diseases, particularly skin cancer.
