Question

Which of the following statements correctly state(s) the location or function of the cells in the epidermis and dermis? Select all that apply. Keratinocytes are located in the stratum basale in the epidermis and the hair follicle of the dermis.

Answer 1

Answer:

Keratinocytes are located in the stratum basale in the epidermis and the hair follicle of the dermis. This statement is correct.

Explanation:

Keratinocytes are in the stratum basale of the epidermis, which is the deepest layer of the epidermis; from this layer, they ascend to the stratum spinosum, then to the stratum granulosum, then to the stratum lucidum if the skin is thick like the one that is in our hands or soles, and lastly they end in the stratum corneum. While the keratinocytes move from one layer to the next one, they change their characteristics.

Keratinocytes are also in hair follicles, they are similar to the keratinocytes from the dermis, but have some differences, such as their reproduction capacity.
