epidermis

Also known as outermost skin cells

capa externa de la piel

AI overview

The epidermis is the thin, outermost layer of your skin that sits above two deeper layers called the dermis and hypodermis. It protects you by blocking harmful germs from entering your body and controlling how much water your skin loses to the air.

La epidermis, en los vertebrados, es la capa externa de la piel, un epitelio escamoso estratificado , compuesto de queratinocitos que proliferan en su base y se diferencian progresivamente, a medida que son empujados hacia el exterior. La epidermis es la barrera más importante del cuerpo al ambiente externo de la piel . En los humanos, su grosor varía desde un mínimo de 0,1 mm en los párpados, a un máximo de 1,5 mm en las palmas de las manos y en las plantas de los pies. Su origen embrionario es ectodérmico. En los artrópodos, la epidermis está formada por una sola capa de células, cúbicas o cilíndricas; produce una secreción que forma una capa protectora externa, la cutícula.
