In view of their close proximity to the lingual lymphatic tissues, the glands were also thought to be involved in antimicrobial action and local immune response (Nair & Schroeder, 1983)[PMCID:PMC2667924] a group of tubulo-acinar serous glands located beneath the circumvallate and foliate papillae of the tongue and their ducts open into the trough at the base of the papillae. The saliva from posterior deep lingual glands is known to modulate the microenvironment at taste reception sites, and affect chemoreception (Gurkan & Bradley, 1988) and it is an important source of growth factors for taste receptor cells (Morris-Wiman et al. 2000)[PMCID:PMC2667924] UBERON:0013475 von Ebner gland Wikipedia:Von_Ebner's_gland FMA:293448 posterior lingual serous gland von Ebner's gland A serous salivary gland which resides adjacent to the moats surrounding the circumvallate papillae in the posterior one-third of the tongue, anterior to the terminal sulcus. posterior deep lingual gland
