where does the papillary layer of the skin lie?
dermis
the dermis is structurally divided into two areas: a superficial area adjacent to the epidermis, called the "papillary region", and a deep thicker area known as the "reticular region".

the papillary region is composed of loose areolar connective tissue. it is named for its fingerlike projections called "papillae", that extend toward the epidermis. the papillae provide the dermis with a "bumpy" surface that interdigitates with the epidermis, strengthening the connection between the two layers of skin.

the lamina propria, like all forms of connective tissue proper, has two layers: papillary and dense. the papillary layer is the more superficial layer of the lamina propria. it consists of loose connective tissue within the connective tissue papillae, along with blood vessels and nerve tissue. the tissue has an equal amount of fibers, cells, and intercellular substance. the dense layer is the deeper layer of the lamina propria. it consists of dense connective tissue with a large amount of fibers. between the papillary layer and the deeper layers of the lamina propria is a capillary plexus, which provides nutrition for the all layers of the mucosa and sends capillaries into the connective tissue papillae.
