===Dermis===
===Dermis===
The epidermis interfaces with the underlying dermis at the '''basement membrane zone (BMZ)'''. The binding includes anchoring junctions called ''hemidesmosomes'' and ''focal adhesions''. The former comprise extra cellular matrix (ECM) proteins such as '''laminin-5''' and '''collagen type IV''' molecules, which form the lamina densa part of the BMZ, while the lamina lucida is composed of '''Collagen type V'''. '''Collagen type VII''' is important in forming anchoring fibrils between the dermis and the basal lamina.
The '''dermis''' consists of dense fibrous tissue composed of '''collagen type I, III and V''', with some elastin fibres and provides a supporting mattress for the carriage of blood vessels, lymphatic vessels, nerves and sensory receptors, '''hair follicles''', sebaceous and sweat glands, with circulating white cells.
