epidermiszben

Epidermiszben is a Hungarian term referring to the epidermis, the outermost layer of the skin in vertebrates. This thin, protective shield is crucial for maintaining the body's integrity and function. The epidermis is avascular, meaning it does not contain blood vessels, and receives its nutrients from the underlying dermis.

The epidermis is composed of several layers, the most prominent being the stratum corneum, a tough, waterproof outer layer made of dead keratinocytes. These cells are constantly shed and replaced by new cells migrating from the stratum basale, the deepest layer of the epidermis. Other layers include the stratum lucidum, stratum granulosum, and stratum spinosum, each with specialized roles in skin development and protection.

Key functions of the epidermis include acting as a barrier against pathogens, preventing water loss, and protecting against UV radiation. It also contains melanocytes, cells responsible for producing melanin, the pigment that gives skin its color and offers protection from the sun. The thickness of the epidermis varies across the body, being thicker on areas like the palms of the hands and soles of the feet.
