Which of the following cells and their functions are correctly matched?
A) Keratinocytes - provide sense of touch and pressure
B) Melanocytes - protects cells in the stratum corneum from damaging effects of sun's rays
C) Dendritic cells - activate the immune system
D) Tactile cells - protection

Question

Quizplus · Accepted Answer

Dendritic cells are specialized cells in the epidermis that play a key role in activating the immune system, both in response to infections and other environmental stimuli. They act as antigen-presenting cells that capture foreign antigens and present them to other cells of the immune system to initiate an immune response.

The other choices are incorrect:
A) Keratinocytes are the most abundant cells in the epidermis and are responsible for producing keratin, a tough protein that helps form the protective barrier of the skin. They do not provide a sense of touch and pressure.
B) Melanocytes produce melanin, a pigment that gives color to the skin and helps protect cells in the deeper layers of the skin from the damaging effects of the sun's rays. They do not protect cells in the stratum corneum.
D) Tactile cells, also called Merkel cells, are specialized cells located in the basal layer of the epidermis that play a role in the sense of touch. They do not provide protection.
