lecture quiz #2 Flashcards
Exocrine glands
Has a duct
Endocrine Glands
does not have a gland
Major Salivary Glands
gland is a distance from duct
Minor Salivary Glands
secretes directly into oral cavity
Histological Configuration
Glands consists of specialized epithelial cells that produce saliva
-Secretive Cells
-Duct Cells
Secretive Cells
cells that become our gland tissue
Duct Cells
cells responsible for creating hollow tubes
Basic Cellular Structure
Acini (grape cluster shape)
-serous cells
-mucous cells
Major Salivary Glands
-Parotid Gland
-Submandibular Gland
-Sublingual Gland
Parotid Gland
-location: in front and below ear
-25% of total saliva
-serous
——-> serous produces amylase which is important for digestion of carbohydrates
-Associated ducts: Stenson’s Duct, near #3 & 14 on buccal mucosa
Submandibular Gland
-Location: near angle of mandible
-65% of total saliva
-serous and mucous —> creates mucin (produces mucous)
-Associated Ducts: Wharton’s
-Sialolith: Salivary Stone
Strafe’s Defect: associated with submandibular gland
Sublingual Gland
-Location: floor of mouth
-10% of total saliva
-serous and mucous
-Associated Ducts: Bartholin’s Duct –>empties under the tongue, multiple ducts of Rivinius opens (Rivian’s Duct) in the area of the sublingual fold
Minor Salivary Glands
-Multiple sites: buccal and labial mucosa, tip of tongue, posterior dorsal surface of tongue
-Drains directly into oral cavity
-600-1,000 in total
Saliva
-99% water, colorless and sticky
-excrete 1-2 liters a day
-helps mastication
Saliva contains
-Salts (potassium, sodium, calcium, (buffers saliva, repairs tooth structure))
-Glycoproteins: hooks up with bacteria to produce pellicle (thin layer that protects tooth)
-protein
-Antimicrobial agents (antibodies)
-WBC
-Epithelial cells
-Bacteria (oral flora)
