There are three major salivary glands: parotid gland (Glandula parotis), submandibular gland (Glandula submandibularis) and the sublingual gland (Glandula sublingualis) in the mouth. Further, there is the pancreas (Pankreas) that delivers its secretions into the lumen of the duodenum. Further small salivary glands are located in the tongue and in the mucosa of the palate.
Oral salivary glands are all eccrine exocrine glands and are classified as:

name of the group	name of the gland	secretion mode	histological characteristics	position	duct opening
Glandulae salivatores majores main salivary glands	Gl. parotidea parotid gland	serous	narrow acini, intercalated ducts, long striated ducts, fat cells in the stroma; one large excretory duct	in the retromandibular fossa	Papilla ductus parotidei opposite to molars 16,17 / 26,27
	Gl. submandibularis submandibular gland	seromucous (serous>mucous)	tubulo-acinar end pieces, v.Ebner demilunes, myoepithelial cells, striated ducts, one large excretory duct	in the submandibular space	Caruncula sublingualis on the base of the frenulum linguae
	Gl. sublingualis sublingual gland	mucoserous (mucous>serous)	tubulo-acinar end pieces, v.Ebner demilunes, myoepithelial cells, short striated ducts, many excretory ducts	lateral posterior above the mylohyoid muscle	several openings on top of tips along the sublingual plica
Glandulae salivatores minores small salivary glands	Gll. sublinguales minores small sublingual glands	mucoserous (mucous>>serous)	hardly any acini, mainly tubular end pieces, no striated ducts, The posterior end of this group is called the glossopalatine glands	along the sublingual plica on the floor of the mouth	several openings on top of tips along the sublingual plica
	Gll. labiales labial glands	seromucous (serous>mucous)	compound tubulo-acinar, no striated ducts	in the mucosa of the upper and lower lip	mucosa of the upper and lower lip
	Gll. buccales inner buccal glands	mucoserous (mucous>serous)	compound tubulo-acinar, no striated ducts	in the mucosa of the cheek	several openings into the mucosa of the cheek
	Gll. molares outer buccal glands	mucoserous (mucous>serous)	compound tubulo-acinar, no striated ducts	outside on top of the buccinator muscle	several openings into the mucosa of the cheek
	Gll. palatinae palatine glands	mucous	compound tubular, no striated ducts	in the palatine mucosa	several openings into the mucosa of the palatum
Glandulae linguales lingual glands	Gl. lingualis anterior (Nuhn) anterior lingual gland	mucous	compound tubular, no striated ducts	beneath the tip of the tongue	mucosa beyond the tip of the tongue
	Gll. linguales posteriores posterior lingual glands	mucous	compound tubular, no striated ducts	beyond the lingual tonsil	crypts of the lingual tonsil
	Gll. gustatoriae von Ebner's glands	serous	branched acinar glands	mucosa beneath tongue papillas with taste buds	open into the ditches between lingual papillas

construction of a larger salivary gland:
The major part of the secretion is produced by the epithelial cells around the acini of the gland. After the acinar or tubulo-acinar end piece (Terminologia histologica: Portio terminalis) which may also be a demilune of Ebner (Terminologia histologica: Semiluna serosa) small intercalated ducts (Terminologia histologica: Ducti intercalati) with a monolayer of cubic epithelium transport the secretion into an intralobular duct whose monolayered columnar epithelial cells show a "basal striping". This striping is caused by regularly stacked mitochondria in deep infoldings of the cell membrane (--> example image) and is visible in light- and electron microscopy. The pancreas (and the lacrimal gland), however, are devoid of this "basal striping". The corresponding parts of their excretory ducts are just called intralobular ducts. When such a duct leaves the lobe of the gland, it becomes an interlobular duct (Terminologia histologica: Ductus interlobularis) and is surrounded by connective tissue. The columnar epithelium then begins to show an additional basal cell layer, i.e. is a bilayered columnar epithelium. Depending on the size of the gland many of such ducts join to form one or more interlobar ducts (Terminologia histologica: Ducti interlobares) which further join into a main excretory duct which has a pseudostratified epithelium.
