What is the Histological Composition of Papillary Structures?
Papillary structures generally consist of a core of connective tissue, which includes collagen fibers, blood vessels, and sometimes nerves. This core is covered by a layer of epithelial cells, which can vary depending on the location and function of the papillae. For example, in the skin, the papillae are covered by keratinized stratified squamous epithelium, while in the kidneys, they are lined by simple cuboidal or columnar epithelium.
