Which skin layer is primarily responsible for sensation and contains nerves?

The dermis is the skin layer primarily responsible for sensation. This layer is located beneath the epidermis and is thicker than it. The dermis contains a rich supply of nerve endings, which are essential for sensing touch, pressure, pain, and temperature. Additionally, the dermis houses blood vessels, hair follicles, and various glands, contributing to the overall functionality of the skin.

In contrast, the epidermis is the outermost layer of skin that primarily serves as a protective barrier and does not contain nerves. The subcutaneous layer, situated beneath the dermis, is primarily composed of fat and connective tissue, providing insulation and cushioning but not sensory functions. The stratum germinativum is a specific layer within the epidermis where new skin cells are generated, and it also does not contain nerve endings for sensation.
