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 decides to use rubber bands to represent the function of elastin in _____.

A) Sebaceous glands
B) Hair follicles
C) Collagen fibers
D) Keratinocytes

Answer 1

Hannah uses rubber bands to represent elastin in the dermis layer of skin to show its elasticity.

Step-by-step explanation:

Hannah decides to use rubber bands to represent the function of elastin in the dermis layer of skin, giving it elasticity and resilience. Elastin allows skin to return to its original position when it is poked or pinched. So, the correct answer to Hannah's task is not sebaceous glands, hair follicles, collagen fibers, or keratinocytes but is rather implied to be linked to the elasticity of the skin, which is a key property of the dermis provided by elastin fibers.
