Papillary layer: location, function, structure - Kenhub
WEBOct 30, 2023 · The papillary layer forms irregular projections known as the dermal papillae. They interlace with the epidermal ridges and contain small vessels organized in subpapillary vascular plexus.
5.1 Layers of the Skin – Anatomy & Physiology
WEBA finger-like projection, or fold, known as the dermal papilla (plural = dermal papillae) is found in the superficial portion of the dermis. Dermal papillae increase the strength of the connection between the epidermis and dermis; the greater the folding, the stronger the connections made (Figure 5.1.4).
