what are the 10 layers of skin

It is also home to your pores, which allow oil and sweat to escape.There are conditions that start in the epidermis layer of your skin. It’s the only layer that is visible to the eyes. In some areas, like the eyelids, it’s very thin. The epidermisis composed of keratinized, stratified squamous epithelium. It's thickest on the palms of the hands and soles of the feet (1.5 millimeters). Skin has two main layers, both of which serve a purpose. The epidermis consists of a type of tissue known as keratinized squamous epithelium. These structures populate the landscape of our skin. Beneath the two layers is a layer of subcutaneous fat, which also protects your body and helps you adjust to outside temperatures. A The stratum basale is a single layer of cells primarily made of basal cells. In much of the developed world, insufficient exercise coupled with the ready availability and consumption of high-calorie foods have resulted in unwanted accumulations of adipose tissue in many people. A In a growing fetus, fingerprints form where the cells of the stratum basale meet the papillae of the underlying dermal layer (papillary layer), resulting in the formation of the ridges on your fingers that you recognize as fingerprints.

This increased melanin accumulation protects the DNA of epidermal cells from UV ray damage and the breakdown of folic acid, a nutrient necessary for our health and well-being. Exposure to the UV rays of the sun or a tanning salon causes melanin to be manufactured and built up in keratinocytes, as sun exposure stimulates keratinocytes to secrete chemicals that stimulate melanocytes. This barrier protects you from bacteria, changing temperatures, and chemical exposure.Your skin also feels sensation, communicating with your brain what is going on around you. Although neither is fatal, it would be hard to claim that they are benign, at least to the individuals so afflicted.Other changes in the appearance of skin coloration can be indicative of diseases associated with other body systems.
