Which layer lies beneath the epidermis and contains connective tissue, hair follicles, and glands?

The layer that lies beneath the epidermis and contains connective tissue, hair follicles, and glands is the dermis. This layer is essential for providing strength and elasticity to the skin due to its composition of collagen and elastin fibers. It also houses a variety of structures, including blood vessels, nerve endings, and the appendages of the skin such as hair follicles and sweat and sebaceous glands.

Understanding the role of the dermis is crucial in the context of the skin's functionality. For example, the connective tissue in the dermis not only supports the epidermis but also plays a vital role in thermoregulation and sensation due to the presence of numerous sensory receptors. Furthermore, the presence of hair follicles and glands allows for the secretion of oils and sweat, which contribute to maintaining homeostasis.

The other options mentioned refer to different layers or components associated with the skin. The hypodermis, also known as the subcutaneous layer, lies below the dermis and serves to anchor the skin while providing insulation and cushioning. The basal layer refers specifically to the bottom layer of the epidermis, where new skin cells are generated, while the term subcutaneous layer is often used interchangeably with hypodermis to describe the fatty tissue layer below the
