What is the name for dead cells that form over a wound during the healing process?

The term for dead cells that form over a wound during the healing process is known as a crust. When a wound occurs, the body's natural response includes the formation of a protective layer made up of dried blood, serum, and dead cells, which acts as a barrier against further injury or infection. This crust is an integral part of the healing process, as it helps protect the underlying tissues while new skin cells regenerate beneath it.

Fissures refer to deep cuts or cracks in the skin, while scales are thin flakes or layers that may occur on the skin's surface as a result of conditions like psoriasis or eczema. Keloids, on the other hand, are overgrown scar tissue that can develop after a wound heals. Each of these terms describes different skin conditions or responses, but none specifically refer to the protective layer formed during the initial healing phase that is described by the term crust.
