Associated with the circumvallate papillae are serous glands located in the lamina propria. These glands are also known asvon Ebner's glands (arrow). The ducts (arrowhead) from these glands open to the surface at the base of the circumvallate papillae. The secretions are thought to dissolve the substances that generate the sensation of taste and, therefore, are involved in the stimulation of the taste sensation.
