nahapiirkonnal
Nahapiirkonnal is Estonian for the dermal region of the skin, referring to the layer located between the epidermis and the subcutaneous tissue. In anatomical terms, the nahapiirkonnal comprises two sublayers: the papillary dermis, which forms a connection with the epidermis, and the deeper reticular dermis. The dermis is mainly connective tissue rich in collagen and elastin fibers, along with fibroblasts, immune cells, blood vessels, and a network of nerves. It also contains skin appendages such as hair follicles, sebaceous glands, and sweat glands.
Functions of the nahapiirkonnal include providing mechanical support and skin strength, supplying elasticity, and facilitating thermoregulation
Clinical relevance varies with age, sun exposure, and injury. Aging and ultraviolet radiation can reduce collagen
In summary, nahapiirkonnal denotes the skin’s dermal region, a structurally and functionally vital layer supporting form,
