What two major layers constitute the dermis, and what components are in each layer?
Guida verificata passo dopo passo1
Identify the two major layers of the dermis: the papillary layer and the reticular layer.
Describe the papillary layer as the upper, thinner layer composed mainly of loose connective tissue, containing capillaries, sensory neurons, and dermal papillae that interlock with the epidermis.
Explain that the papillary layer contains components such as fibroblasts, mast cells, macrophages, and small blood vessels that nourish the epidermis.
Describe the reticular layer as the deeper, thicker layer made of dense irregular connective tissue, which provides strength and elasticity to the skin.
List the components of the reticular layer, including collagen and elastin fibers, larger blood vessels, lymph vessels, sweat glands, sebaceous glands, hair follicles, and deep pressure receptors.
