[TFD][VHOG] FMA:55093 The most common oral glands in mammals are the salivary glands. There are usually three primary pairs of salivary glands, named for their approximate positions: mandibular (submandibular or submaxillary), sublingual, and parotid.[well established][VHOG] Wikipedia:Submandibular_gland EV:0100061 mandibular gland EMAPA:18812 in mice, submandibular gland development initiates as a thickening of the oral epithelium; around E12 an initial (single) epithelial bud on a stalk grows into a condensing neural crest-derived mesenchyme; clefts in the epithelium result in 3-5 epithelial buds at E13.5, and branching morphogenesis occurs with continued proliferation, successive rounds of cleft formation, duct elongation, and duct lumen formation, so that by E14 the gland is highly branched (multi-lobed); functional differentiation, with the appearance of proacinar cells and secretory products begins after E15 and continues to birth; acinar differentiation continues postnatally with final differentiation of the granular convoluted tubules at puberty[MGI:anna] UBERON:0001736 major salivary gland submandibular gland primordium
