Question

As a student in an esthetic program, Hannah is tasked with building a three-dimensional model of the layers of the skin. Her model must include captions describing each skin layer and connect skin histology and physiology to esthetics. Hannah visits a craft store to purchase supplies from which she will construct her model.

Hannah chooses a sheer, transparent fabric to model the stratum _____, the clear layer of dead skin cells under the stratum corneum.

a) Basale
b) Spinosum
c) Granulosum
d) Lucidum

Answer 1

Hannah should use the sheer, transparent fabric to model the stratum lucidum, which is the clear layer of dead skin cells located under the stratum corneum in her skin layers project.

Step-by-step explanation:

Hannah is constructing a model of skin layers. She has chosen a sheer, transparent fabric to represent the stratum lucidum, which is the correct answer to her question. The stratum lucidum is a clear layer of dead skin cells located just beneath the stratum corneum, primarily found in the thicker skin of the palms and soles. The epidermis itself is the surface layer of the skin, which includes, from deepest to most superficial, the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum (when present), and the stratum corneum. Hannah's model will help illustrate how these layers are involved in skin histology and physiology, linking to practices in esthetics such as microdermabrasion, which aids in removing some of the dry, upper layer of the epidermis.
