Q

Which artery and nerve come off the incisive canal?

A

an incisive foramen is located on the

right and left sides that transmits the terminal branches of the nasopalatine n. and sphenopalatine vessels.

Q

Course of maxillary artery

A

3 branches supplying the palate

  • Sphenopalatine artery
  • Greater palatine artery
  • lesser palatine artery

3 branches that supply maxillary arch
- Anterior, middle, posterior alveolar arteries

Q

Course of sphenopalatine artery

A

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
17
Q

Course of greater palatine artery

A

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.
18
Q

Course of lesser palatine artery

A

Descending palatine from 3rd part of maxillary a.

  • > travels in lesser palatine canal
  • > supplies soft palate and palatine tonsil
19
Q
A
  1. Facial a.
  2. Ascending palatine a.
  3. External carotid a.
  4. Ascending pharyngeal a
20
Q

Arterial Supply of the Teeth

A
  1. Posterior superior alveolar a.
  2. Middle superior alveolar a.
  3. Anterior superior alveolar a
  4. Incisive a.
  5. Mental a.
  6. Inferior alveolar a.
21
Q

Course of Anterior superior alveolar (3)

A

infraorbital a.

  • > passes through inferior orbital fissure
  • > into infraorbital canal
  • > descends via alveolar canals to supply maxillary sinus and anterior teeth
22
Q

Course of Middle superior alveolar (2)

A

infraorbital a.

  • > passes through inferior orbital fissure
  • > into infraorbital canal
  • > descends via alveolar canals to supply maxillary sinus and supplies plexus at the canine
23
Q

Course of Posterior superior alveolar (1)

A

Arises before maxillary a.

  • > enters pterygopalatine fossa
  • > enters infratemporal surface of maxilla
  • > to supply maxillary sinus, premolars, and molars
24
Q

Course of incisive arter (4)

A

Source: inferior alveolar artery

-> Supplies anterior teeth

25
Q

Course of mental artery (5)

A

Source: inferior alveolar artery

-> Supplies labial gingiva of anterior teeth

26
Q

Course of mental artery (6)

A

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
27
Q

Arterial Supply of the Tongue

A
  1. Deep lingual a.
  2. Sublingual a.
  3. Lingual a.
  4. Dorsal lingual a
28
Q

Course of lingual artery

A

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
