Verified step by step guidance

Understand the structure of the epidermis: The epidermis is the outermost layer of the skin, part of the cutaneous membrane, and is composed of several types of cells.

Identify the primary cell type: The majority of the cells in the epidermis are keratinocytes, which are responsible for producing keratin, a protein that provides strength and protection.

Differentiate between cell types: While melanocytes, Merkel cells, and Langerhans cells are present in the epidermis, they serve different functions. Melanocytes produce melanin, Merkel cells are involved in sensory perception, and Langerhans cells play a role in immune response.

Focus on keratinocytes: Keratinocytes make up about 90% of the epidermal cells and are crucial for the protective barrier function of the skin.

Conclude with the primary cell type: Given their abundance and role, keratinocytes are the primary cell type that makes up the epidermis of the cutaneous membrane.
