18
Q

CNs that convey pain information from their areas to the spinal trigeminal nucleus

A

CNs VII, IX and X

19
Q

Receives information about discriminative sensation and light touch of the face as well as conscious propioception of the jaw via first order neurons

A

Principal Sensory Nucleus

20
Q

Involved with propioception of the face, that is, the feeling of position of the muscles

A

Mesencephalic Nucleus

21
Q

Contains no chemical synapses but are electrically coupled —> neurons of this nucleus are pseudounipolar cells receiving propioceptive information from the mandible, and sending projections to the motor trigeminal nucleus to mediate monosynaptic jaw jerk reflexes

A

Mesencephalic Nucleus

22
Q

The only structure in the CNS to contain the cell bodies of a primary afferent, which are usually contained within ganglia

A

Mesencephalic Nucleus

23
Q

Contains motor neurons that innervate muscles of the first branchial arch, namely the muscles of mastication, the tensor tympani, tensor veli palatini, mylohyoid, and anterior belly of the digastric

A

Trigeminal Motor Nucleus

24
Q

Muscles of mastication

A

–masseter
–temporalis
–medial pterygoid
–lateral pterygoid

•Others
–Tensor veli palatini
–mylohyoid
–anterior belly of digastric
–tensor tympani
25
Q

Controls the muscles of facial expression

A

Facial nerve

26
Q

Conveys taste sensations from the anterior two-thirds of the tongue and oral cavity

A

Facial nerve

27
Q

Supplies preganglionic parasympathetic fibers to several head and neck ganglia

A

Facial nerve

28
Q

Provides parasympathetic innervation to several glands, including the nasal, palatine, lacrimal and pharyngeal glands

A

Greater petrosal nerve

29
Q

Provides motor innervation for stapediusmuscle in middle ear

A

Nerve to stapedius

30
Q

Controls movements of some of the scalp muscles around the ear

A

Posterior auricular nerve

31
Q

Five major facial branches (in parotid gland)

A

temporal, zygomatic, buccal, marginal mandibular, cervical

32
Q

Aids in tasting, swallowing and salivary secretions. Its superior and inferior (petrous) ganglia contain the cell bodies of pain fibers

A

Glossopharyngeal Nerve

33
Q

CN IX
Taste from the posterior one-third of the tongue and information from carotid baroreceptors and carotid body chemoreceptors

A

Solitary nucleus

34
Q

CN IX

Lower motor neurons for the stylopharyngeus muscle

A

Nucleus ambiguus

35
Q

CN IX

Somatic sensory fibers from the middle ear

A

Spinal nucleus of trigeminal nerve

36
Q

CN IX

Parasympathetic input to the parotid and mucus glands

A

Inferior salivatory nucleus

37
Q

Sends parasympathetic output to the viscera, especially the intestines

A

Dorsal nucleus of vagus

38
Q

CN X
Gives rise to the branchial efferent motor fibers of the vagus nerve and preganglionic parasympathetic neurons that innervate the heart

A

Nucleus ambiguus

39
Q

CN X

Receives afferent taste information and primary afferents from visceral organs

A

Solitary nucleus

40
Q

CN X
Receives information about deep/crude touch, pain, and temperature of the outer ear, the duraof the posterior cranial fossa and the mucosa of the larynx

A

Spinal trigeminal nucleus

41
Q

Provides motor innervation from the CNS to two muscles of the neck

A

Accessory Nerve

sternocleidomastoid and the trapezius muscles

42
Q

Muscle that ilts and rotates the head

A

Sternocleidomastoid muscle

43
Q

Elevates shoulder and adducts the scapula

A

Trapezius

44
Q

Supplies motor fibres to all of the muscles of the tongue, except the palatoglossus muscle

A

Hypoglossal Nerve
