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 molds her clay into _____-shaped cells connected by _____ to represent the cells in the stratum spinosum.

a) Cuboidal - Desmosomes
b) Squamous - Tight Junctions
c) Columnar - Gap Junctions
d) Spherical - Hemidesmosomes

Answer 1

Hannah should mold her clay into cuboidal-shaped cells and interconnect them via desmosomes to accurately represent the cells in the stratum spinosum, which are known for their spiny appearance and strong intercellular connections.

Step-by-step explanation:

Hannah molds her clay into cuboidal-shaped cells connected by desmosomes to represent the cells in the stratum spinosum. The name 'stratum spinosum' is derived from the spiny appearance of this layer, which is due to the protruding cell processes that interlock via desmosomes, strengthening the bond between the cells. In histology, the study of the shape and arrangement of cells in tissue, it is essential to accurately depict these structures to understand their function in the skin's physiology, such as providing strength and resilience to the skin as part of its protective barrier.
