Pns 2-1 Flashcards
Name the sensory root of the facial cranial nerve.
Nervus intermedius
The apparent origin of the facial nerve lies at the inferior pontine sulcus, just lateral to the recess between the ___________ and ____________.
olive and inferior cerebellar peduncle
Name four cranial nuclei and their modality related with the facial nerve.
- Nucleus of facial - branchial efferent, 2. Superior salivatory nucleus - visceral efferent, 3. Tractus solitarius - afferent, 4. Spinal nucleus of trigeminal - general sensory
Name four cranial nuclei and their target organ(s) related with the facial nerve.
- Nucleus of facial - facial and auricular muscles, 2. Superior salivatory nucleus - nervus intermedius, 3. Tractus solitarius nucleus - ventral thalamic nuclei, 4. Spinal nucleus of trigeminal nerve - auricular concha and external acoustic meatus
Name the nucleus, which sends visceral motor fibers to the submandibular, sublingual & lacrimal glands.
Superior salivatory nucleus sends to sensory root (nervus intermedius)
Name the visceral efferent cranial nucleus and their peripheral ganglion
- OCULOMOTOR - CILIARY, 2. SUP. SALIVATORY - SUBMANDIBULAR, 3. PTERYGOPALATINE, INF. SALIVATORY - OTIC
At the lateral end of the acoustic meatus, the facial nerve enters the _________ to reach the ____________.
facial canal to reach the stylomastoid foramen
Name four nerves, which communicate with the facial nerve at the stylomastoid foramen
GLOSSOPHARYNGEAL, VAGUS, GREAT AURICULAR, AURICULOTEMPORAL
Name two ganglia, which communicate with the genicular ganglion.
- Pterygopalatine ganglion through greater petrosal nerve, 2. Otic ganglion through lesser petrosal nerve
Name the modality(s) of the greater petrosal nerve.
Special sensory and visceral efferent
The greater petrosal nerve conveys between what?
genicular ganglion and pterygopalatine ganglion
The deep petrosal nerve conveys between __________ and ___________.
internal carotid plexus and nerve of pterygoid canal
The external petrosal nerve conveys between ___________ and __________.
the middle meningeal sympathetic plexus and genicular ganglion
The lesser petrosal nerve conveys between _________ and _________.
otic ganglion & tympanic plexus
In the foramen lacerum, the greater petrosal nerve joins with the ________ from ___________ & it becomes the nerve of the pterygoid canal.
deep petrosal nerve from the internal carotid plexus
Before the facial nerve emerges from the stylomastoid foramen, it receives the auricular nerve from _______.
Vagus
Name the nervous communications in sequence from the genicular ganglion to the pterygopalatine ganglion for the visceral efferent fibers.
GENICULAR - GREATER PETROSAL - NERVE OF PTERYGOID CANAL - PTERYGOPALATINE GANG.
