Basal granular cells belong to one of the types of cells in the peripheral part of the eosinophilic channel of the epithelium in the digestive system of animals. The cells are round in shape with processes on the underside, collecting rough and direct carbon dioxide from the epithelium into the lumen of the skin gutter. The basal cells of the granular layer are located subepithelial and form a bilayer layer located between the basal and granular layers. From the basal cells of the granular region they extend along each vessel, where each eddy in the entire capillary has one cell. The content and functional significance of granular cells is that they generate potential and regulate the functioning of the bipolar nerve cell, and also perform regeneration
