Anatomy Salivary Glands Flashcards
2 types of saliva produced by salivary glands
Serous, mucous
Serous saliva
Watery, mainly protein fluid
Mucous saliva
Thick, mainly carb fluid
Where are minor salivary glands located
Tissues of buccal, labial, and lingual mucosa, soft palate, lateral of hard palate, floor of mouth
A vein that begins below the chin, descends near the midline, and drains into the external jugular vein
Anterior jugular vein
Serves the posterior hard palate and posterior lingual gingiva
Greater palatine nerve
The sixth cranial nerve serves the eye muscle
Abducens nerve
Opens the oral cavity at the parotid papilla
Parotid duct
Cranial nerve that innervates all muscles of mastication
Fifth (trigeminal nerve)
Which of the salivary glands is largest
Parotid
Another name for parotid duct
Stensen duct
What artery is behind the ramus with 5 branches
Inferior alveolar artery
Which artery supplies the maxillary molars, premolar teeth and gingiva
Posterior superior alveolar artery
How many pairs of nerves are connected to the brain
12
Which division of the trigeminal nerve subdivides into the buccal, lingual, and inferior alveolar nerves
Mandibular division
Second largest salivary gland
Submandibular gland
3rd largest salivary gland
Sublingual gland
What percent of total volume of saliva does the parotid gland provide
25%
What duct does the saliva pass through from the parotid gland
Parotid duct (stensens)
What percent of saliva does the submandibular gland produce
60-65%
What duct does the submandibular gland release saliva into
Submandibular or Whartons duct
What percent salivary volume does the sublingual gland provide
10%
What duct does the sublingual gland release saliva into
Sublingual or Bartholins duct
What might block the salivary glands
Sialolith
What artery arises from the aorta and subdivides into internal and external arteries
Common carotid artery
What supplies blood to the brain and eyes
Internal carotid artery
What supplies blood to the face and mouth
External carotid artery
Larger of 2 terminal branches of external carotid
Maxillary artery
What are the three sections the maxillary artery divides into
Inferior alveolar, pterygoid, pterygopalatine
What are the three divisions or the trigeminal nerve
Ophthalmic, maxillary, mandibular
What does the nasopalatine nerve do
Supplies the mucoperiosteum palatial to maxillary anterior teeth
Greater palatine nerve
Posterior palatine foramen, supplies mucoperiosteum
Inferior alveolar nerve divides into
Mylohyoid nerve, small dental nerves, mental nerve, incisive nerve
What is the mandibles blood supply
Inferior alveolar arteries
What is the Von Ebner’s salivary gland associate with on the tongue
Circumvallate lingual papillae
Which duct spills saliva on maxillary molars
Parotid
Pathway of blood flow
LV, A, RB/L, CC, EC, MA, teeth, PP, MV, RV, jugular/facial, SVC, RA, RV, PA, C, PV, LA
