What are the Specialized Cells in Epidermal Tissues?
Several specialized cells are present in the epidermal layer:
- Keratinocytes: The most abundant cells in the animal epidermis, responsible for producing keratin, a protein that strengthens the skin. - Melanocytes: Located in the stratum basale, these cells produce melanin, which gives skin its color and protects against UV radiation. - Langerhans Cells: Part of the immune system, these cells detect and present antigens to T-cells. - Merkel Cells: Sensory cells that respond to light touch. - Guard Cells: In plants, these cells flank each stoma and regulate its opening and closing.
