Question

Quizplus · Accepted Answer

The stratum basale (also known as the basal layer) is the layer of the epidermis composed of a single layer of columnar cells that undergo mitosis, which means they continually divide and give rise to new cells that migrate toward the surface of the skin.

Answer: D
 The stratum spinosum (also known as the prickle cell layer) is composed of several layers of cells that have spine-like projections, which gives them a spiky appearance. These cells contain keratin and provide strength and support to the epidermis.

Answer: C
 The stratum granulosum (also known as the granular layer) consists of 3-5 layers of flattened cells that contain granules of keratohyalin, a substance that helps to form keratin fibers in the upper layers of the skin.

Answer: B
 The stratum lucidum (also known as the clear layer) is a thin, translucent layer of dead skin cells that is found only in thick, hairless skin such as the palms of the hands and soles of the feet.

Answer: A
 The stratum corneum (also known as the horny layer) is the outermost layer of the epidermis and is composed of layers of flattened, dead cells that are filled with keratin. This layer helps to protect the skin from external damage and water loss.
