The oral cavity
What do salivary glands drain into?
It keeps the oral cavity moist and mixes with food to facilitate mastication.
What is the function of saliva?
Through papilla.
How do salivary glands secrete saliva into the oral cavity?
Mucoid secretions.
What type of secretions do minor salivary glands produce?
Serous fluid secretions.
What type of secretions do major salivary glands produce?
Three pairs.
How many pairs of major salivary glands are there?
Parotid Salivary Gland.
What is one of the major salivary glands?
Zygomatic Salivary Gland.
What is another major salivary gland?
Mandibular Salivary Gland.
What is the third major salivary gland?
Parotid salivary gland
what structure is 1?
Parotid duct
What structure is 2?
Mandibular salivary gland
What structure is 3?
Mandibular lymph nodes
What structure is 4?
Lingual molar salivary gland
What is structure 1?
Tooth 409
What is structure 2?
may be confused for an abnormal structure, avoid during extractions around.
clinical significance of lingual molar salivary gland in cats
sites of nerve blocks
clinical significance of infraorbital & middle mental foramen
site of the inferior alveolar nerve
clinical significance of mandibular foramen
helps recognize maxilla on radiographs
clinical significance of palatine fissure
normal radiolucent line to help split the right and left mandibles
clinical significance of mandibular symphysis
major blood/ nerve supply run through here, be cautious during extractions
importance of the mandibular canal
Maxillary
What nerve does the green line represent
infraorbital
What nerve does the red line represent
Inferior alveolar nerve
What nerve does the purple line represent
mental nerve
what nerve does the blue line represent
It aids in healing and control of infection.
What is the importance of blood supply in the oral cavity?
Damage to the routes of arteries and veins supplying the oral cavity and teeth.
What should be avoided during dental/oral surgical procedures?
Hemostasis.
What should be planned for if blood vessels cannot be avoided during surgery?
the mandibular foramen and canal to supply mandibular teeth and bone
Inferior alveolar artery courses through where?
performing surgical extraction of mandibular canine teeth
3 mental branches of inferior alveolar artery can be encountered when?
hard and soft palate, periosteum, alveolar bone of maxillary teeth
what do major and minor palatine arteries supply?
alveolar
several branching of what arteries supply the maxillary teeth?
maxillary artery emerging from infraorbital canal
The infraorbital artery is a continuation of what?
