Pigment can be found in several layers of the epidermis. in which layers would you expect to find the cells that produce melanin? stratum spinosum stratum lucidum stratum basale stratum granulosum

Melanocytes are located in the stratum basale.

Explanation:

Melanin is the pigment responsible for skin color. It is produced by melanocytes located in the base of the epidermis.

The epidermis is made up of five cell layers, which have different functions: Stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.    

Stratum basale is the innermost germinative, single, basal layer of the epidermis composed of basal cuboidal-shaped cells. These cells are the precursor of keratinocytes, this is why this layer is also called germinativum. In this basal layer, there are also Merkel cells as well as melanocytes.

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.
