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.

In addition, Hannah notes that _____ form(s) on the surface of the stratum corneum, which contribute(s) to the protective function of this epidermal layer.

a) Hair follicles
b) Sweat glands
c) Microvilli
d) Desmosomes

Answer 1

Desmosomes form on the surface of the stratum corneum and contribute to the protective function of this skin layer by creating strong, intercellular connections.

Step-by-step explanation:

On the surface of the stratum corneum, which is the outermost layer of the epidermis, desmosomes form, contributing to its protective function. Desmosomes are specialized structures that create strong, intercellular connections, helping to bind cells together, which is essential for the integrity and resilience of this epidermal layer against mechanical stresses. They do not provide an immediate barrier against water or pathogens, which is a function of the keratin and lipids found within the cells of the stratum corneum. Therefore, in response to Hannah's project in constructing a model that includes skin histology and physiology related to esthetics, it's important to highlight that answer (d) desmosomes are the forms that develop on the surface of the stratum corneum contributing to its protective role.
