Final answer:
The layers of the skin are the epidermis, dermis, and subcutaneous tissue (hypodermis). The epidermis is the outermost layer that acts as a protective barrier. The dermis is the middle layer that provides structural support, and the subcutaneous tissue is the deepest layer that provides insulation and padding. correct option is B.
Step-by-step explanation:
Layers of the Skin
Our skin is made up of three layers: the epidermis, dermis, and subcutaneous tissue.
1. Epidermis:
The epidermis is the outermost layer of the skin. It acts as a protective barrier against harmful substances and prevents water loss. It is composed of several layers of epithelial cells, with the innermost layer called the basal layer. The epidermis also contains cells called melanocytes, which produce the pigment melanin that gives skin its color.
2. Dermis:
The dermis is the middle layer of the skin, located below the epidermis. It provides structural support and houses various structures such as blood vessels, nerve endings, sweat glands, and hair follicles. The dermis is composed of connective tissue containing collagen and elastin fibers, which give the skin strength, elasticity, and resilience.
3. Subcutaneous Tissue:
The subcutaneous tissue, also known as the hypodermis, is the deepest layer of the skin. It is primarily made up of adipose tissue (fat cells) and serves as insulation and padding for the body.
