Trigeminal nerve

Which cranial nerve is the trigeminal nerve

Fifth cranial nerve

What are the three divisions of the trigeminal nerve

1) Ophthalmic

2) Maxillary

3) Mandibular

Where does the trigeminal nerve divide into its 3 divisions

semilunar ganglion

Anterior Superior Alveolar Nerve

Teeth:

- Maxillary central, lateral and canine

Mucosa:

-labial mucosa of central, lateral and canine

Middle Superior Alveolar Nerve

Teeth:

-Maxillary premolars and mesiobuccal root of 1st molar

Mucosa:

- Buccal mucosa of premolars

Posterior Superior Alveolar Nerve

Teeth:

- Maxillary 2nd and 3rd molars

-Distobuccal and palatal roots of 1st molar

Mucosa:

-Buccal mucosa of 1st, 2nd, and 3rd molar

Nasopalatine Nerve

Teeth:

-None

Mucosa:

Palatal mucosa of the central, lateral and canine

Only nerve to cross the midline

Greater palatine nerve

Teeth:

-None

Mucosa:

Palatal mucosa of premolars and molars

What foramen is associated with the nasopalatine nerve

incisive foramen

What protects the incisive foramen

incisive papilla

What foramen is associated with the greater palatine nerve

greater palatine foramen

Inferior Alveolar Nerve

Teeth:

-all mandibular teeth

Divides at mental foramen into the mental nerve and the incisive nerve

mental nerve

Mucosa:

-facial mucosa of the 2nd premolar to the central incisor

This nerve exits through the mental foramen

incisive nerve

Teeth:

-2nd premolar to the central incisor

This nerve does not exit through the mental foramen

At which foramen does the inferior alveolar nerve divide

the mental foramen

Which division of inferior alveolar nerve exits the mental foramen

mental nerve

Which division of the inferior alveolar nerve does not exit the mental foramen (remains in the bone)

incisive nerve

Buccal nerve

Mucosa:

-buccal mucosa of the 1st, 2nd and 3rd molars

Lingual nerve

Mucosa:

- all lingual mucosa, floor of the mouth and the anterior 2/3 of the tongue
