What else can I help you with?
Melanocytes and keratinocytes work together in protecting the skin from the UV damage when keratinocytes?
Accumulate the melanin granules on their superficial portion, forming a pigment that protects DNA from UV radiation
What is the difference of melanocytes and keratinocytes?
Answer taken from the article:Costin & Hearing (2007). Human skin pigmentation: Melanocytes modulate skin color in response to stress. The Faseb Journal, 21(4), 976-994."Melanin biosynthesis is a complex pathway that appears in highly specialized cells, called melanocytes, within membrane-bound organelles referred to as melanosomes. Melanosomes are transferred via dendrites to surrounding keratinocytes, where they play a critical role in photoprotection. The anatomical relationship between keratinocytes and melanocytes is known as 'the epidermal melanin unit' and it has been estimated that each melanocyte is in contact with ∼40 keratinocytes in the basal and suprabasal layers."Translated: Melanocytes produce melanin in nice little packages called, melanosomes. These melanosomes are then transferred to neighboring keratinocytes (i.e., the hair follicle) through dendrites. This is how the hair follicle gets its color, even though the actual hair follicle doesn't produce melanin itself.
One square centimeter of skin's surface contains how many cells?
Approximately 1 million cells are found in just one square centimeter of skin's surface. These cells include various types such as epidermal cells, melanocytes, and keratinocytes, which work together to protect the body and maintain skin health.
What are the different types of skin cells and how do they contribute to the overall health and function of the skin?
There are three main types of skin cells: keratinocytes, melanocytes, and Langerhans cells. Keratinocytes make up the majority of the skin and provide a protective barrier against external factors. Melanocytes produce melanin, which gives skin its color and helps protect against UV radiation. Langerhans cells are part of the immune system and help defend against infections and foreign substances. Together, these cells work to maintain the skin's health and function by protecting it from damage and regulating its immune response.
The epidermis is a void of?
The epidermis is the outermost layer of the skin that serves as a protective barrier against external factors such as bacteria, UV radiation, and chemicals. It consists of several layers of cells, including keratinocytes, melanocytes, and Langerhans cells, that work together to maintain skin integrity and function.
How does cilated work?
Yes it does work because like what it is it is not an experiment it is somthing that is stated in somthing that happens everyday how does your body show you are cold the hairs on the surface of your skin
When painting what is involve in surface preparation?
It's like pre-treatment for removing scale, dirt, or else from a surface before you do a coating work on it. It's often called blasting.
On what surfaces does a clip on flashlight work?
Clip on flashlights work on pretty much any surface that has a shelf like appearance. This is because it needs something to clip on to. Surface should be between eighth inch to inch and a half for most models.
How do you figure the square footage of a dome?
Tricky. You need to flatten out the surface to work it out. Depends on the shape - if it's like a hemisphere then you can use the properties of a sphere - volume = 4/3 Pi R3 and surface area = 4 Pi R2 so if your dome is like half a sphere then its surface area = 2 Pi R2 and you can measure the radius R so can work it out!
What is a surface table?
A Surface table is a strong table you work on in engineering and the material on the surface can vary.
What kind of surface will adhesion of tape work better on?
rough surface
How does surface area work?
It would help if the question was less obscure. What do you mean by "work"? How the surface area affects chemical processes (for example the surface area of catalysts), or diffusion, or surface areas and friction?
