25 lis 2015 · Rete ridges occur where the epidermis is thickest and extend deep into the dermis. Fibroblasts (yellow) are present throughout the dermis. Nerves and Schwann cells (light blue) are present in a complex arrangement throughout the dermis.
Rete ridges surround the dermal papillae, which can be seen as small extensions protruding from the papillary dermis within the epidermis. These two structures are perfectly embedded; the alternation of a rete ridge with a dermal papilla creates a characteristic repetitive and wave-shaped pattern.
