Question 1
Question
Types of the epidermis' cells
[blank_start]Melanocytes[blank_end] produce pigment.
Merkel cells, also known as [blank_start]tactile[blank_end] [blank_start]epithelial[blank_end] cells, attach to [blank_start]sensory[blank_end] nerve ends creating "[blank_start]light[blank_end] [blank_start]touch[blank_end]" receptors.
