1

This nucleus is responsible for motor function of the trigeminal nerve

motor nucleus

2

This nucleus is responsible for touch, vibration, and proprioceptive functions of the trigeminal nerve

main sensory nucleus

3

This nucleus is responsible for pain and temperature sensation as well as trigeminalo-mediated relfexes of the trigeminal nerve

spinal trigeminal nucleus

4

This is an example of a trigeminal reflex

blink reflex

5

This portion of the spinal trigeminal nucleus is responsible for trigeminally-mediated reflexes

anterior portion

6

This nucleus is responsible for proprioception of the gums/jaw

mesencephalic

7

What is anatomically unique about the mesencephalic nucleus?

it is located in the CNS (only place where 1˚ afferents are located within the CNS)

8

Where does the central process of the mesencephalic nucleus terminate?

trigeminal motor nucleus

9

Where do the axons of the main sensory nucleus terminate on the thalamus?

ventroposterior medial thalamus (VPM)

10

What type of sensation is carried bilaterally in the trigeminal nerve?

main sensory nucleus information from the oral cavity

11

What nucleus does not produce axons that cross the midline?

mesencephalic

12

How many synapses are involved in the jaw jerk reflex

1 (!)

13

Damage to one side of the trigeminal motor nucleus causes what deficit?

deviation on ipsilateral side
-->motor neurons do not cross midline
