Dermal is an adjective that pertains to the skin or the layers of tissue that make up the skin. It refers to anything related to or affecting the skin, particularly its structure, characteristics, and functions. The word is derived from the Latin term "dermis," which means "skin."
In a biological context, dermal can describe various aspects of the skin and its components. For instance, it can refer to dermal layers, which are the distinct levels or strata of tissue in the skin. These layers are composed of various types of cells, such as epithelial cells and fibroblasts, that provide support, protection, and other functions.
Additionally, dermal can describe the dermis itself, which is the inner layer of the skin lying underneath the epidermis. The dermis contains blood vessels, nerve endings, hair follicles, sweat glands, and other structures that contribute to the skin's vitality and functionality.
Dermal can also be used to describe medical conditions, treatments, or procedures related to the skin. For instance, dermal fillers are injectable substances used to restore volume and reduce wrinkles on the skin's surface. In this context, dermal refers to the specific type of treatment aimed at improving the appearance of the skin.
Overall, dermal is a versatile term used to characterize any phenomenon, structure, or process associated with the skin or its layers.
