Which layer of the skin contains fat cells, blood and lymph vessels, and hair follicles?

The subcutaneous layer, also known as the hypodermis, plays a crucial role in the structure of the skin. It is located beneath the dermis and is primarily composed of adipose (fat) tissue. This layer serves several purposes, including providing insulation to help regulate body temperature, storing energy, and cushioning underlying muscles and bones.

In addition to fat cells, the subcutaneous layer contains blood and lymph vessels, which are essential for nutrient delivery and waste removal. The presence of hair follicles in this layer is also significant, as they originate here and extend through the dermis to reach the surface of the skin.

Understanding the layered structure of the skin is important for various practices in massage therapy, as each layer contributes to overall skin health and integrity. This foundational knowledge can enhance a therapist's approach to client care and treatment techniques.
