C
Keratinocytes
D
Melanocytes
Verified step by step guidance1
Understand the structure of the epidermis, which is the outermost layer of the skin, and its role in protection and sensation.
Identify the different types of cells present in the epidermis: keratinocytes, melanocytes, Langerhans cells, and Merkel cells.
Recognize that keratinocytes are the most abundant cell type in the epidermis, making up about 90% of the cells. They are responsible for producing keratin, a protein that provides strength and waterproofing to the skin.
Differentiate between the functions of the other cell types: melanocytes produce melanin (pigment), Langerhans cells are involved in immune response, and Merkel cells are associated with sensory function.
Conclude that the majority of cells in the epidermis are keratinocytes, based on their abundance and primary role in forming the protective barrier of the skin.
