EPIDERMAL CELL Meaning and
Definition
-
Epidermal cells are specialized cells that make up the outermost layer of the skin, known as the epidermis. The epidermis serves as a protective barrier and plays a crucial role in maintaining the integrity and function of the skin.
Epidermal cells are flat, scale-like cells that are tightly packed together to form a continuous layer. They are primarily composed of a protein called keratin, which gives the skin its strength and waterproofing properties. These cells are primarily involved in providing protection against physical injury, preventing the entry of harmful microorganisms, and regulating the loss of water from the body.
There are several types of epidermal cells with distinct functions. The most abundant cells are keratinocytes, responsible for producing and storing the protein keratin. Melanocytes, another type of epidermal cell, are responsible for producing the pigment melanin, which gives color to the skin and protects it from ultraviolet (UV) radiation damage.
Langerhans cells, also present in the epidermis, are part of the immune system and play a role in recognizing and presenting foreign substances to other immune cells. Merkel cells, found in the deepest part of the epidermis, are involved in sensory perception, particularly in touch sensations.
In summary, epidermal cells are the building blocks of the outer layer of the skin, providing protection, water regulation, pigment production, and immune responses.
