Question

functions of epidermal cell types

match the descriptions with the correct epidermal cell type.

a table depicts the components of the cell by its type. the column headers are function and cell type.

\

$$\begin{tabular}{|l|l|} \\hline function & cell type \\\\ \\hline found in deepest layer; produce pigment & (click to select) \\\\ \\hline most abundant cell type; provide waterproofing to skin & (click to select) \\\\ \\hline scattered within epidermis; phagocytic cells & (click to select) \\\\ \\hline \\end{tabular}$$

options:

• epidermal dendritic cells
• fibroblasts
• keratinocytes
• melanocytes

Explanation:

Identify pigment-producing cells

Using the Melanocytes knowledge point

• Melanocytes reside in the deepest epidermal layer (stratum basale) and produce melanin pigment.

Identify waterproofing cells

• Keratinocytes are the most abundant epidermal cells.
• They produce keratin, which provides structural strength and waterproofing to the skin.

Identify phagocytic cells

• Epidermal dendritic cells (Langerhans cells) are scattered within the epidermis.
• They function as phagocytic antigen-presenting immune cells.

Answer:

Function	Cell Type
Most abundant cell type; provide waterproofing to skin	Keratinocytes
Scattered within epidermis; phagocytic cells	Epidermal dendritic cells
