Which skin layer is rich in blood vessels and nerves?

• A. Epidermis
• B. Dermis
• C. Subcutaneous
• D. Muscle

Answer: (B)

The layer that carries nourishment and sensory information to the skin is the dermis. It is rich in a dense network of blood vessels that supply nutrients and oxygen to the skin, and it houses numerous nerve endings and receptors for touch, pressure, and temperature. The epidermis above it has no blood vessels of its own, relying on diffusion from the dermal vessels, while the subcutaneous layer below contains fat and larger vessels but is generally considered a supporting layer rather than a primary skin layer. So, the dermis is the layer most associated with both extensive vascularization and innervation.
