3. Which cells in the epidermis are
responsible for immune surveillance?
• A) Keratinocytes
• B) Melanocytes
• C) Langerhans cells
• D) Merkel cells
☑VERIFIED ANSWER: C) Langerhans cells
Rationale: Langerhans cells are dendritic
cells in the epidermis that function as
antigen-presenting cells, playing a key role
in the skin's immune response.
4. Which layer of the skin contains blood
vessels, nerve endings, and hair follicles?
