MIXED CRANIAL NERVE Flashcards
Trigeminal ganglion is a sensory ganglion.
[True / False]
True
The functional components of vagus nerve include
[A] Taste sensation [B] Branchiomotor [C] Parasympathetic sensory [D] Somatic motor [E] Parasympathetic motor
The functional components of vagus nerve include
[A] Taste sensation
[B] Branchiomotor –> 4th
[C] Parasympathetic sensory
[E] Parasympathetic motor
Facial nerve has
a. Special afferent from tongue
b. special visceral efferent supply.
c. General visceral efferent supply.
d. General visceral afferent supply
e. Somatic efferent supply
Facial nerve has
a. Special afferent from tongue
- -> Taste from tongue anterior 2 thirds
b. special visceral efferent supply.
- -> facial muscle-2nd branchial arch muscles
c. General visceral efferent supply.
- -> Salivary and lacrimal glands
________ from pontomedullary junction –> ________ of temporal bone –>_____ canal –> above the middle ear cavity–> ______ wall of middle ear cavity –> ______ foramen –> in the face within ______ –> _________ supply of the face.
[facial nerve] from pontomedullary junction –> [internal acoustic meatus] of temporal bone –>[facial] canal –> above the middle ear cavity–> [Posterior] wall of [middle] ear cavity –> [Stylomastoid] foramen –> in the face within [parotid gland] –> [motor] supply of the face.
Regarding trigeminal nerve:
a. is attached to anterolateral aspect of pons.
b. motor nucleus is in the pons. Sensory nucleus in all 3 parts of Brain Stem, but motor only in pons
c. receives taste sensation from anterior part of the tongue.
d. receives somatic sensation from the face.
e. All three divisions its nucleus have both motor and sensory functions’ mandibular division has motor along with sensory, other two divisions only sensory
Regarding trigeminal nerve:
a. is attached to anterolateral aspect of pons.
b. motor nucleus is in the pons. –> Sensory nucleus in all 3 parts of Brain Stem, but motor only in pons
d. receives somatic sensation from the face.
The parasympathetic motor supply of facial nerve is to
a. sublingual salivary gland.
b. submandibular salivary gland
c. anterior part of the tongue
d. lacrimal gland.
e. facial muscle
The parasympathetic motor supply of facial nerve is to
a. sublingual salivary gland.
b. submandibular salivary gland
d. lacrimal gland.
Both motor and sensory (mixed) cranial nerves include
a. abducent
b. Trigeminal
c. vagus
d. Glossopharyngeal
e. Facial
Both motor and sensory (mixed) cranial nerves include
b. Trigeminal
c. vagus
d. Glossopharyngeal
e. Facial
In lower motor neuron lesion of facial nerve (Bell’s palsy), opposite side lower half of facial palsy occurs.
[True / False ]
[False]
Feedback:
Its in UMN lesion
In LMN lesion same side & both upper & lower part of face paralysis
Single correct answer: The three major branches of vagus nerve in the neck region are
a. Pharyngeal, internal laryngeal and recurrent laryngeal nerves
b. Pharyngeal, superior laryngeal and internal laryngeal nerves
c. Pharyngeal, external laryngeal and recurrent laryngeal nerves
d. Pharyngeal, superior laryngeal and recurrent laryngeal nerves
e. Pharyngeal, superior laryngeal and external laryngeal nerves
d. Pharyngeal, superior laryngeal and recurrent laryngeal nerves
Match the cranial nerve nuclei and their function.
Nucleus tractus solitarius →
Salivatory nuclei →
Somatic motor nucleus →
Nucleus ambiguus →
Branchiomotor supply @ Parasympathetic motor supply @ Taste sensation @ voluntary movements by skeletal muscle
Match the cranial nerve nuclei and their function.
The correct answer is:
Nucleus tractus solitarius → Taste sensation,
Salivatory nuclei → Parasympathetic motor supply,
Somatic motor nucleus → voluntary movements by skeletal muscle,
Nucleus ambiguus → Branchiomotor supply
The common foramen of cranium through 9th, 10th and 11th cranial nerves pass through is
Jugular foramen
Trigeminal nerve nuclei are present in all three parts of brainstem.
[True / False]
True
