- Oral cavity proper
- Vestibule
5 arteries that supply the lips with source
Hint - image
- Infraorbital a.
- Superior labial a. of the facial a.
- Buccal a.
- Inferior labial a. of the facial a.
- Mental a.
What are the 3 nerves supplying the lips
- Superior labial branch of the infraorbital n.
- Buccal n.
- Mental n.
- > All sensory innervation to the skin of this region is supplied by the trigeminal n.
Identify 2
- Transverse palatine rugae
Which artery and nerve come off the incisive canal?
an incisive foramen is located on the
right and left sides that transmits the terminal branches of the nasopalatine n. and sphenopalatine vessels.
- Tensor veli palatini
- Levator veli palatini
- Palatoglossus
- Palatopharyngeus
- Levator veli palatini
- Tensor veli palatini
- Musculus uvulae
- Palatopharyngeus
2. Palatoglossus
- Lingual n.
- Submandibular duct
- Mylohyoid m.
- Geniohyoid m.
- Lingual n.
- Submandibular duct
- Mylohyoid m.
4 arteries supplying oral cavity
- Sphenopalatine a.
- Greater palatine a.
- Lesser palatine a.
- Maxillary a
Source of maxillary artery
External carotid artery
Course of maxillary artery
3 branches supplying the palate
- Sphenopalatine artery
- Greater palatine artery
- lesser palatine artery
3 branches that supply maxillary arch
- Anterior, middle, posterior alveolar arteries
1 branch supplying mandibular arch
- Inferior alveolar artery
Course of sphenopalatine artery
3rd part of maxillary artery
- > sphenopalatine foramen (nasal cavity)
- > give rises to posterior superior nasal branches, posterior superior lateral branch, and posterior superior medial branch
- > continues into incisive canal
Course of greater palatine artery
Descending palatine from 3rd part of maxillary a.
- > greater palatine a that exist greater palatine foramen
- > passes anteriorly toward incisive foramen to supply hard palate
- > anastomose with terminal branch of sphenopalatine a.
Course of lesser palatine artery
Descending palatine from 3rd part of maxillary a.
- > travels in lesser palatine canal
- > supplies soft palate and palatine tonsil
- Facial a.
- Ascending palatine a.
- External carotid a.
- Ascending pharyngeal a
Arterial Supply of the Teeth
- Posterior superior alveolar a.
- Middle superior alveolar a.
- Anterior superior alveolar a
- Incisive a.
- Mental a.
- Inferior alveolar a.
Course of Anterior superior alveolar (3)
infraorbital a.
- > passes through inferior orbital fissure
- > into infraorbital canal
- > descends via alveolar canals to supply maxillary sinus and anterior teeth
Course of Middle superior alveolar (2)
infraorbital a.
- > passes through inferior orbital fissure
- > into infraorbital canal
- > descends via alveolar canals to supply maxillary sinus and supplies plexus at the canine
Course of Posterior superior alveolar (1)
Arises before maxillary a.
- > enters pterygopalatine fossa
- > enters infratemporal surface of maxilla
- > to supply maxillary sinus, premolars, and molars
Course of incisive arter (4)
Source: inferior alveolar artery
-> Supplies anterior teeth
Course of mental artery (5)
Source: inferior alveolar artery
-> Supplies labial gingiva of anterior teeth
Course of mental artery (6)
Source: 3rd part of maxillary artery
- > Supplies all of the mandibular teeth
- > descends inferiorly following inferior alveolar n. to enter mandibular foramen and terminates into mental and incisive aa. at region of 2nd premolar
Arterial Supply of the Tongue
- Deep lingual a.
- Sublingual a.
- Lingual a.
- Dorsal lingual a
Course of lingual artery
External carotid artery
-> Lingual artery
- > posterior border of hyoglossus m -> gives of 2-3 branches of dorsal lingual arteries
- > anterior border of hyoglossus -> gives off sublingual artery
- > become deep lingual artery at ventral surface of tongue
- > anastomoses with deep lingual artery from another side
