Lectures 9 (pteyrgopalatine) 10 (oral cavity) and 11 (histology) clinical stuff from lecture Flashcards
Describe the Kiesselbach area
Where 5 of the arteries that supply the nose meet and come together in a capillary bed that can bleed profusely
What are the 5 arteries that are involved in the Kiesselbach area?
- sphenopalatine 2. anterior ethmoidal 3. posterior ethmoidal 4. greater palatine 5. superior labial
This muscle is in line with the superior pharyngeal constrictor and attaches to the pterygomandibular raphe
Buccinator
What is the only pharyngeal muscle that is not innervated by the vagus nerve?
stylopharyngeus
What is Waldeyers lymphatic ring?
It is a ring of tonsils that surround the pharynx made up of the palatine, pharyngeal, and the lingual tonsils that when swollen can impeded the airway; all drain into the deep cervical nodes
What will be immediately lateral to the tonsil when it is surgically removed?
Glossopharyngeal nerve
When you go to pop your ears, what muscle is acting?
Tensor veli palatini
Which muscle acts on the eustachian tube?
Levator veli palatini
If there is an injury in CN X or CN V3, what is possible in regards to swallowing?
Paralysis of both the tensor veli palatini or the levator veli palatini which can lead to difficulty closing the soft palate, and food can come out the nose… yikes
If you have a tooth that dies, what is happening?
the pulp has been damaged and the dentin is no longer able to receive nutrients from the pulp, and the tooth dies
When people get dentures, describe what happens to the alveolar bone
Since there are not any teeth that are being held in the gomphosis joints by the PDL, then the alveolar bone starts to dissolve and changes the structure of the face entirely
This is why when old people remove their teeth, their chin looks different
