Question

which cells in the epidermis have a specific immune function?

a. melanocytes
b. langerhans cells
c. keratinocytes
d. merkel cells

clear my choice

Explanation:

Analyze the function of each cell type in the epidermis

• Melanocytes: Produce melanin pigment to protect against ultraviolet radiation.
• Langerhans cells: Dendritic cells of the skin that function as antigen-presenting cells, playing a key role in the immune response.
• Keratinocytes: Produce keratin, forming the structural barrier of the skin.
• Merkel cells: Function as mechanoreceptors for light touch sensation.

Identify the cell with a specific immune function

• Langerhans cells are specialized dendritic cells residing in the stratum spinosum of the epidermis, acting as the primary immunological barrier.

Answer:

• a. Melanocytes
• b. Langerhans cells (Correct answer)
• c. Keratinocytes
• d. Merkel cells
