Mandibular Division Flashcards
Where does the mandibular division exit the cranial vault
Through the foramen ovale
What does the mandibular division leave the cranial vault as
A large sensory root and a small motor root
Where do the large sensory root and small motor root combine to form the mandibular division
The infratemporal fossa
The Mandibular division carries what kind of fibers
Both motor and sensory
Where does the mandibular division carry sensation from
Skin over mandible, posterior cheek, posterior temple, and from the mucosa of the lower oral cavity and cheeks
How many m. does the mandibular division innervate
- 4 of which are the m. of mastication
What 2 branches of the mandibular division are given off in the infratemporal fossa
Recurrent meningeal branch and Medial pterygoid n.
What are the m. of mastication
Masseter, Temporalis, Med. and Lat. pterygoid m.
The recurrent meningeal branch (nervus spinosum) reenters the cranium via what
The Foramen spinosum
The recurrent meningeal branch (nervus spinosum) carries sensory info from where
The dura of the middle cranial fossa, ant. cranial fossa, and calvarium
The Medial pterygoid n. is the motor supply for what
The medial pterygoid m.
What do the medial pterygoid n. fibers that pass through the otic ganglion supply
Tensor veli palatine and tensor tympani
Is the anterior division of the mandibular n. predominantly motor or sensory
Motor
Is the posterior division of the mandibular n. predominantly motor or sensory
Sensory
What 4 n. does the anterior division of the mandibular n. give rise to
Masseter n., Deep Temporal n., Lat. Pterygoid n., and Buccal n.
The masseter n. provides motor to the masseter, and carries sensory info from where
Temporomandibular joint
The ant. and post. branches of the deep temporal n. both supply
The temporalis m.
What info does the Buccal n. carry
Sensation from the cheek and buccal gingivae of the molars
Which division (ant. or post.) of the mandibular division is larger
Posterior
What does the auriculotemporal n. pass through
The parotid gland
Where does the auriculotemporal n. carry sensory info from
The skin of the temple and ear
T/F:The auriculotemporal n. carries some postganglionic parasympathetic fibers from the otic ganglion
True
What kind of info does the lingual n. of the posterior division carry
Sensory from the mucosa of the oral cavity
Where does the lingual n. combine with the chorda tympani
In the infratemporal fossa
What kind of info does the inferior alveolar n. carry
Sensory info from the lower teeth and chin. has 2 branches
What does the incisive branch supply
The incisors, canines, and 1st premolars and adjacent gingivae
What does the mental n. supply
The labial gingivae adjacent to the incisors and the skin of the lower lip and chin
Prior to entering the mandibular foramen, the motor fibers carried in the inf. alveolar n. diverge and supply what
The mylohyoid and ant. belly of digastric
What 2 autonomic ganglia communicate with the mandibular division
Submandibular and Otic ganglia
The submandibular ganglion receives preganglionic fibers from where after it combines with the chorda tympani
The lingual n.
Where does the otic ganglion send postganglionic fibers to the parotid gland via what
The auriculotemporal n.
T/F: The lingual n. may convey some taste info to the chorda tympani
True
