Palate Flashcards
What does the palate do
separates the oral cavity from the nasal cavity
What bony structures make up the hard palate
Palatine process of maxillae -anterior 2/3 of hard palate
Horizontal Plates of palatine- posterior 1/3 of hard palate
What covers the hard palate
mucous membrane and includes the palatine glands
What is the soft palate
fibromuscular element covered by mucous membrane and palatine glands
What structure is found at the posterior termination of the soft palate
The Uvula
What does the soft palate doe during swallowing
the soft palate elevates, closing the oral pharynx from the nasopharynx
What are the 5 muscles of the palate
Levator Veli Palatini Tensor Veli Palatini Musculus Uvulae Palatoglossus Palatopharyngeus
What is the origin of the levator veli palatini
temporal bone and Eustachian tube cartilage
What is the action of the Levator Veli Palatini
elevate and retract palate
What is the origin of the Tensor Veli Palatini
sphenoid bone and Eustachian tube cartilage
What is the action of tensor veli palatini
tightens and flattens the palate
What is the origin of the musculus uvulae
Hard palate
What is the action of the musculus uvulae
elevate the uvula
What is the palatoglossal fold
fold of mucous membrane that covers the palatoglossal muscle
What is the origin of the palatopharyngeus muscle
Hard and soft palate
What is the action of the palatopharyngeus
elevates the pharynx
What is the palatopharyngeal fold
mucous membrane that covers the palatopharyngeal muscle
What is the Tonsilar Fossa
space between the palatoglossal and palatopharyngeal folds along wall of pharynx
What is contained inside of the tonsilar fossa
Palatine tonsils
What are all muscles of the palate innervated by? Whats the exception?
CN10
Tensor Veli Palatini innervated by CN10 and V3
What supplies general sensory innervation to the palate
Palatine Branches of V2 (maxillary)
What supplies taste innervation to the palate
Greater Petrosal Nerve (branch of CN7)
What supplies parasympathetic innervation to palatine glands
pregang: greater petrosal nerve
postgang: sphenopalatine ganglion
What arteries supply the palate
Palatine branches of maxillary and facial arteries
