This illustration depicts a cross-section of human skin, including the epidermis, dermis, and subcutaneous layers. In the dermal layer, one can observe hair follicles, sebaceous glands, sweat glands, blood vessels, and nerves. The illustration also highlights the presence of Pacinian corpuscles, which are sensory receptors responsible for pressure detection. The vascular network is represented by red lines, indicating blood flow throughout the skin layers.
