salivary glands are comprised of CT & epithelial cells TERM 2 The CT supports the gland, but the epithelial cells DEFINITION 2 secrete saliva & line the ducts TERM 3 major & minor glands refers to DEFINITION 3 Size & amount of secretion TERM 4 Serous, Mucous, and Mixed (serous demilunes) refers to DEFINITION 4 Type of cells and secretion TERM 5 major glands secrete about _% of the saliva DEFINITION 5 90%
minor glands empty directly into the oral cavity TERM 7 minor glands produce about -% of the saliva DEFINITION 7 5-10% TERM 8 Salivary glands are merocrine, which means DEFINITION 8 they release material by vesicles fusing with cell membranes TERM 9 salivary glands are also exocrine because they DEFINITION 9 secrete their product through ducts TERM 10 serous glands secrete a _ material, mostly _ & small amounts of DEFINITION 10 watery; proteins; carbohydrates
mucous gland cells secrete _ mucin TERM 17 a viscous product which, when mixed with oral fluids, forms mucous which makes saliva thick & viscous DEFINITION 17 mucin TERM 18 serous demilunes occur in _ glands where a cap of serous cells sits on mucous cells DEFINITION 18 mixed TERM 19 The secretion of the serous cells passes through a duct (_ _) which passes between the _ _ into the _ _ _ _ DEFINITION 19 intercellular canaliculus; mucous cells; lumen of the alveolus TERM 20 The basic unit of salivary glands is the _ (or _) DEFINITION 20 alveolus; acinus
This is a cluster of cells that secretes into a terminal collecting duct alveolus / acinus TERM 22 As saliva is produced by the _ _ it is collected in a _ DEFINITION 22 alveolar cells; duct TERM 23 In the minor glands the ducts are _ & empty _
DEFINITION 23 short; directly into the oral cavity TERM 24 In the major glands the ducts are _ & more _ in structure DEFINITION 24 longer; complex TERM 25 In the largest glands (_ & _) there are _ & _ portions of the duct system DEFINITION 25 parotid; submandibular; secretory; excretory
Excretory ducts are located in the connective tissue septa between the lobules & lobes TERM 32 Near its opening the main duct becomes lined with DEFINITION 32 stratified squamous epithelium, continued from the oral cavity TERM 33 3 pairs of major salivary glands DEFINITION 33 Parotid, Submandibular, Sublingual TERM 34 Each major salivary gland secretes a different product, which is determined by DEFINITION 34 the type of secretory cells found in the gland TERM 35 The parotids are the _ glands, but produce only _% of the total saliva DEFINITION 35 largest; 25%
the parotid glands secrete a _ material serous TERM 37 The parotid ducts (_ _) extend anteriorly across the _ muscles, bend toward the _ & open adjacent to the _ _ DEFINITION 37 Stensons ducts; masseter; mouth; maxillary molars TERM 38 The submandibular glands are _ in size, but produce _% of the total saliva DEFINITION 38 intermediate; 60% TERM 39 the submandibular glands secrete DEFINITION 39 a mixed serous & mucous material TERM 40 In the submandibular glands _ cells predominate, with some _ cells and some _ _ DEFINITION 40 serous; mucous; serous demilunes
the sublingual duct opens into the _ _ through the same opening used by the oral cavity; submandibular gland TERM 47 Other smaller ducts of the sublingual gland may also open along the DEFINITION 47 sublingual fold TERM 48 The minor salivary glands are _ numerous than the major glands DEFINITION 48 more TERM 49 _ _ _ are minor salivary glands associated with circumvallate papillae DEFINITION 49 Von Ebners glands TERM 50 the major salivary protein, produced mainly in the parotid gland DEFINITION 50 Amylase
the sublingual gland produces no _ & the submandibular gland only 20% of _ amylase TERM 52 Certain stimuli, such as sour materials, stimulate the _ glands, while carbohydrates tend to increase _ _ DEFINITION 52 serous; mucous production TERM 53 Rate of saliva secretion Tends to be low at _ & increased with stimulation DEFINITION 53 night TERM 54 Taste & smell, as well as , mastication tends to stimulate saliva secretionthis is controlled by the _ _ in the brain***, part of the _ system DEFINITION 54 salivary center, parasympathetic TERM 55 Saliva functions DEFINITION 55
to reduce the acid in the oral cavity, saliva contains buffering mechanisms TERM 62 The tonsillar tissue is a ring of _ _ that surround the _ & protect this area against microbes, foreign cells, & cancer cells DEFINITION 62 3 glands; oropharynx TERM 63 The ring of tonsillar tissue is called _ _ & is made up of the _ tonsil, the _ tonsil, & the _ tonsil (_) DEFINITION 63 Waldeyers ring; palatine; lingual; pharyngeal; adenoid TERM 64 Palatine tonsil tissues are _ & are located in the posterior area of the mouth between the _
