Cranial Nerve VI

A

Facial

26
Q

Facial Sensory, Motor, Both?

A

Both; innervation to muscles responsible for facial expressions plus proprioception sensory feedback from those muscles, Provides PNS/visceral motorfibers to various glands including lacrimal, (tear), nasal, palatine, (tonsils?), submandibular, (salivary), and sublingual, (salivary)., Sensory, (afferent), information from the taste buds on the anterior ⅔ of the tongue.

27
Q

Cranial Nerve VIII

A

Vestibulocochlear

28
Q

Vestibulocochlear Sensory, Motor, Both?

A

Sensory; carrying information concerning equilibrium and movement, (vestibular: proprioception), and hearing

29
Q

Cranial Nerve IX

A

Glossopharyngeal

30
Q

Glossopharyngeal Sensory, Motor, Both?

A

Both; innervating part of tongue and pharynx; somatic motor to and proprioception from a pharyngeal muscle involved in swallowing. PNS efferents, ), information concerning taste and general stimuli such as touch, pressure, etc. from pharyngeal mucosa and posterior tongue; information from chemoreceptors in the carotid body, (O2 and CO2/pH), and pressure receptors in the carotid sinus

31
Q

Cranial Nerve X

A

Vagus

32
Q

Vagus Sensory, Motor, Both?

A

Both; somatic motor innervation of muscles in pharynx and larynx (swallowing and speech respectively) and feedback proprioception. major PNS visceral motor (efferent) outflow to heart, lungs, GI tract and corresponding visceral sensory information allowing feedback regulation; in particular blood pressure monitoring via receptors in the carotid sinus and respiration control via chemoreceptors in the aortic and carotid bodies. taste buds of posterior tongue and mucosa of larynx/pharynx

33
Q

Cranial Nerve XI

A

Accessory

34
Q

Accessory Sensory, Motor, Both?

A

Motor. Function; unique as fusion of CN and first 5 cervical SC nerves, (C1-C5). Purely motor, (efferent), as joins with vagus, (X), to innervate muscles in the larynx, pharynx and soft palate; spinal nerves control muscles that move head and neck

A

Hypoglossal

36
Q

Hypoglossal Sensory, Motor, Both?

A

Motor. the muscles of the tongue; not only for mastication and manipulation of food but also swallowing and speech.
