Mandibular division Flashcards
The Mandibular division exits via foramen ______
Foramen ovale
The sensory and motor roots combine in the ______ ______ to form the mandibular division
Infratemporal fossa
The Mandibular division carries sensation from the skin over the ________, posterior ______, and posterior ______, and also the mucosa of the ______ _____ cavity and cheeks
Mandible
Posterior cheek
Posterior temple
Mucosa of lower oral cavity and cheeks
What two branches of the mandibular division come off in the infratemporal fossa?
Recurrent meningeal nerve
Medial pterygoid nerve
The recurrent meningeal provides sensation to what?
The middle cranial fossa dura mater
The medial pterygoid nerve provides motor supply to what?
Medial pterygoid muscle
Some fibers pass through the OTIC ganglion which gives motor supply to:
Tensor veli palatine
Tensor Tympani
The recurrent meningeal nerve reenter the skull via what opening?
The foramen spinosum
The mandibular nerve divides into two divisions the ________ division which is predominantly ________ and the _______ division which is predominantly _______.
The anterior divisions is predominantly motor
The posterior division is predominantly sensory
What are the branches of the anterior division of the mandibular nerve?
Masseter nerve
Deep temporal nerve
Lateral pterygoid nerve
Buccal nerve
Describe the masseter nerve:
*Anterior division
Supply masseter muscle
Supply TMJ
What does the Deep temporal nerve supply?
The temporallis
What does the lateral pterygoid nerve supply?
The lateral pterygoid muscle
Describe the Buccal nerve:
Major sensory branch of the anterior division of the mandibular division:
Supplies the cheek (mucosal and skin)
Buccal gingivae of the molars
What are the branches of the posterior division of the mandibular division?
Auriculotemporal nerve Inferior alveolar nerve **Mental nerve **Incisive nerve Lingual
Anterior or posterior division of the mandibular divisions is largest?
The posterior division is the largest of the two
