Epidermis Cell Types Quiz

Which cell type in the epidermis is primarily responsible for producing the protein keratin?

• Melanocytes

• Langerhans cells

• Merkel cells

• Keratinocytes

What is the main function of melanocytes in the epidermis?

• To produce keratin

• To provide sensory information

• To produce melanin, which protects against UV radiation

• To act as immune cells

Which epidermal cell type acts as part of the skin's immune response by detecting pathogens?

• Langerhans cells

• Merkel cells

• Keratinocytes

• Basal cells

Where are Merkel cells located, and what is their function?

• In the stratum spinosum, producing keratin

• In the stratum basale, providing touch sensation

• In the stratum granulosum, producing melanin

• In the stratum lucidum, detecting temperature changes

What is the role of basal cells found in the stratum basale layer of the epidermis?

• They produce sweat

• They are stem cells that continuously divide to form new keratinocytes

• They detect pressure and temperature

• They produce oil to protect the skin
