Arterial supply of palatine tonsil
Tonsilar artery from facial artery
Mucus membrane of oral cavity
CN IX (Glossopharyngeal)
Innervation to the lips
Upper lip (V2- infra orbital)
Lower lip (V3- mental, buccal)
Cheek
-Skin innervation
-Muscle and innervation
-Mucous membrane innervation
Skin= V2 infraorbital and V3 buccal
Muscle = buccinator (V3 buccal branch)
Mucous membrane = V3 -buccal branch
Innervation of upper teeth and gums
V2 (posterior and superior alveolar) (superior alveolar enters in infraorbital canal

Greater palatine nerve, nasopalatine nerve
NGreater palatine nerve
Innervation of lower gums and teeth?
Lingual nerve
Inferior alveolar (V3)
Buccal nerve
Mental nerve
Upper and lower vestibular gums
Upper=infraorbital
Lower=mental
Lingual frenulum
Part of tongue that attaches to the floor of the oral cavity
Types of lingual papillae, where they are located and what they do
Filiform papillae- most numerous, no taste buds, cover all of the dorsum of the tongue (thread like)

Fungiform papillae- club-shaped, do contain taste buds

Vallate papillae- 8-12 in number, larger papillae, toward posterior aspect of body, multiple taste buds

Follate-ridges- Occur on lateral aspect of tongue
Sulcus terminalis
Fusion of posterior 1/3 and anterior 2/3 of tongue from bracheophargyngeal eminence meets with tongue buds.
Foramen cecum
Where thyroglossal duct was (thyroid descends through here)
Lingual tonsil
located on the posterior 1/3 of the tongue (behing sulcus terminalis)
Vallate papillae innervation
Glossopharyngeal nerve
Taste
Vagus = taste in area of epiglottis
Glossopharyngeal = taste in posterior 1/3 of tongue
Facial = taste from the anterior 2/3 of tongue
Sensory to tongue
Anterior 2/3= Lingual (V3)
Posterior 1/3 = Glossopharyngeal
Styloglossus

Palatoglossus innervation
Innervated by Vagus nerve (only one with glossus in name not innervated by hypoglossal nerve)
