carotid sinus

the lingual n. supplies sensory or motor innervation

sensory

the hypoglossal n. supplies sensory or motor innervation

motor

What do CN IX and X contribute to?

sensation to root of tongue

what does CN VII (via chorda tympani branch) contribute to

taste ('“special” sensation)

CN V (trigeminal) branches into what nerve, with lingual following after

mandibular n.

What is the role of CN XII (hypoglossal n.)

motor to all extrinsic and intrinsic tongue muscles

A

mandibular branch of V

B

lingual n.

C

hypoglossal n.

most trigeminal n. branches lie fairly

deep

Dental Blocks improve

analgesia and decrease general anesthesia requirements

which block would you use for infraorbital n./infraorbital foramen

rostral maxillary regional block

which block would you use for maxillary n./maxillary foramen

caudal maxillary regional block

which block would you use for middle mental n. /mental foramen

rostral mandibular regional block

which block would you use for inferior alveolar n/mandibular foramen

caudal mandibular regional block

the Rostral maxillary regional block provides regional analgesia to…

Incisors, canine, 1st 3 premolar teeth of the
corresponding side. The adjacent maxillary bone and
surrounding soft tissue are also affected.

the caudal maxillary regional block provides regional analgesia to

Bones, teeth, soft tissues of the upper jaw, including
the hard palate and the soft and hard palatal mucosa
on the corresponding side

the rostral mandibular regional block provides regional analgesia to

Incisors and canine tooth of the corresponding side
along with the adjacent bone. *Note: soft tissues are
better blocked with the caudal mandibular regional
block

the caudal mandibular regional block provides regional analgesia to

All mandibular teeth, mandibular bone, and soft
tissue on the corresponding side rostral to the
injection site

which nerve block is thsi

rostral maxillary block (infraorbital n.)

which nerve block is this

caudal maxillary block (maxillary n.)

which nerve block is this

rostral mandibular block (middle mental n.)

which nerve block is this

caudal mandibular block (inferior alveolar n.)

what should you be careful of with the caudal mandibular block (inferior alveolar n.)

may also cause lingual n. to be blocked, so absent tongue sensation until it wears off

the trigeminal nerve supplies both

sensory innervation and motor innervation

to where does the trigeminal nerve supply sensory innervation

face

jaw

oral tissue

to where does the trigeminal nerve supply motor innervation

muscles of mastication

what is trigeminal neuritis

absent/decreased sensation

dropped jaw

difficulty eating and drinking

most facial n. (CN VII) branches lie fairly

superficial

5

dorsal buccal n. (skeleton)

4

ventral buccal n. (skeleton)

what does the facial nerve innervate

muscles of facial expression

what is facial nerve paralysis

muscle laxity on affected side

in addition, the facial nerve carries parasympathetic fibers innervating glands: __________, ______, ______,_____ and innervates the ____ ____

nasal

lacrimal

mandibular

sublingual salivary

taste buds
