Question

Which way does the epidermis grow?

A. From the stratum lucidum to the stratum spinosum
B. From the stratum basale to the stratum corneum
C. From the stratum corneum to the stratum spinosum
D. From the stratum corneum to the stratum basale

Answer 1

The correct answer is B. From the stratum basale to the stratum corneum.

The epidermis is the outermost layer of the skin and it continuously regenerates itself through a process called epidermal cell turnover. This turnover begins at the deepest layer of the epidermis called the stratum basale. New cells are constantly formed in the stratum basale, and as they mature, they move upwards through the different layers of the epidermis.

Eventually, these cells reach the outermost layer of the epidermis called the stratum corneum, where they become flattened, lose their nuclei, and are eventually shed off from the skin's surface. So, the growth of the epidermis occurs from the stratum basale to the stratum corneum as new cells are produced and push older cells towards the surface.
