Question

which of the following cells and their function are correctly matched?
keratinocytes - provide sense of touch and pressure
melanocytes - protects cells in the stratum corneum from damaging effects of suns rays
dendritic cells - activate the immune system
tactile cells - protection

Explanation:

• Keratinocytes: Produce keratin, which is for protection, not touch and pressure.
• Melanocytes: Produce melanin that protects cells in the stratum basale (not corneum) from UV rays.
• Dendritic cells: Also known as Langerhans cells, they phagocytize foreign substances and activate the immune system.
• Tactile cells: Provide sense of touch, not protection.

Answer:

dendritic cells - activate the immune system
