Anatomy Flashcards
What are the four tongue papillae?
Vallate
Fungiform
Foliate
Filiform
Which of the papillae have tastebuds?
Vallate
Foliate
Fungiform
Where is the terminal sulcus and what does it divide?
The anterior and posterior of the tongue
Where is the foramen cecum and what is its clinical significance embryologically?
It is where the thyroid descends
What are the general parts of the tongue?
Apex
Dorsum
Ventrum
Root
Frenulum
What is the motor function to all the tongue?
CNXII
What is the sensory innervation to the anterior 2/3
Chorda tympani (Special)
Lingual via V3 (Normal)
What is the sensory innervation to the posterior 1/3
CNIX
What are the intrinsic tongue muscles and what innervates them?
Superior longitudinal
Inferior longitudinal
Transverse
Vertical
ALL CNXII
What are the extrinsic muscles of the tongue and what innervates them?
Genioglossus
Hyoglossus
Styloglossus
All CNXII
Palatoglossus
CNX
What is the otic ganglion and where is it?
Innervates parotid via PSNS and it is below foramen ovale
What are the three main salivary glands
Parotid
Submandibular
Sublingual
What is the main gland in normal situations?
Submandibular
What is the main gland when food is ingested
Parotid
Where does the parotid drain to and via what?
Opposite upper second molar
Parotid/Stensons duct
Where does the submandibular drain to and via what?
Floor of mouth
Submandicular/Whartons duct
Where does the sublingual drain to and via what?
Anterior to the submandicular duct and via 8-20 mini ducts
What blood test could reveal parotid gland swelling and infection?
Amylase
What is Freys syndrome?
Cutting of the nerves after parotid surgery causing them to grow back toward the skin.
When eating the skin glands get innervated causing sweating.
You also get ear numbess via great auricular nerve damage
