Which of the following describes the three layers of the skin?

The skin consists of three main layers, which are vital to its function and structure. The correct answer points out these layers as the epidermis, dermis, and subcutaneous layer.

The epidermis is the outermost layer of the skin and serves as a protective barrier, preventing pathogens and environmental damage. It contains keratinocytes, which produce keratin, a protein that contributes to the skin's toughness.

The dermis lies beneath the epidermis and is a thicker layer that houses blood vessels, nerve endings, hair follicles, and glands (such as sweat and sebaceous glands). This layer provides structural support, elasticity, and strength to the skin due to the presence of collagen and elastin fibers.

The subcutaneous layer, also known as the hypodermis, is located beneath the dermis. It consists primarily of fat and connective tissue, acting as an insulator for the body and helping to absorb shock. This layer also helps anchor the skin to underlying structures, such as muscles and bones.

In contrast, other options may introduce inaccuracies. The notion of a muscle layer or an unhealthy layer does not reflect the established anatomical structure of the skin layers. Similarly, while fatty tissue does exist in the subcutaneous layer, referring to it
