Question

The superficial layer of the epidermis that varies in thickness over the body

Answer 1

stratum corneum

Step-by-step explanation:

The superficial layer of the epidermis is called the "stratum corneum." It's the outermost layer and consists of multiple layers of flattened, dead skin cells called corneocytes. These cells are densely packed with keratin, a tough protein that provides strength and resilience to the skin.

The thickness of the stratum corneum can vary across different parts of the body. For instance, it's thicker in areas subject to more wear and tear, like the palms of the hands and the soles of the feet, where it acts as a protective barrier against friction and abrasion. In contrast, it's thinner in more delicate areas like the eyelids.

This layer is crucial for protecting the body against dehydration, pathogens, and environmental stressors, while also aiding in the regulation of water loss from the body.

Answer 2

The epidermis is the outermost layer of the skin that varies in thickness over the body. It is composed of tightly packed epithelial cells and does not have any blood vessels. The thickness of the epidermis can range from 0.05 mm on the eyelids to 1.50 mm on the palms of the hands and soles of the feet.

It is composed of tightly packed epithelial cells and does not have any blood vessels. The epidermis is made up of four or five layers of cells, depending on its location in the body. The thickness of the epidermis can range from 0.05 mm on the eyelids to 1.50 mm on the palms of the hands and soles of the feet.
