Pregunta 1
Pregunta
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.
Most superficial keratinocytes are dead. They begin in the stratum [blank_start]basale[blank_end] and are pushed to the stratum [blank_start]corneum[blank_end].
