Cranial nerve nuclei #1

1- Spinal trigeminal nucleus (V) 2- Spinal trigeminal tract (V)

Sample slide questions:

1) Are the fibers in #2 ascending or descending? Where will they synapse?
2) Neurons from which cranial nerves synapse in #1? Where do neurons with their cell bodies in this nucleus send their axons?

 

Cranial nerve nuclei #2

1- Spinal trigeminal nucleus (V)

2- Spinal trigeminal tract (V)

3- Solitary nucleus and tract (VII, IX, X)

4- Dorsal motor nucleus of vagus (X)

5- Hypoglossal nucleus (XII)

Sample slide questions:

1) Is the information processed in #5 motor, sensory, or both? What type of damage would result in unilateral destruction of this nucleus?
2) What type of information is processed in #4?

 

Cranial nerve nuclei #3

1- Spinal trigeminal nucleus (V)

2- Spinal trigeminal tract (V)

3- Solitary nucleus and tract (VII, IX, X)

4- Dorsal motor nucleus of vagus (X)

5- Hypoglossal nucleus (XII)

Sample slide questions:

1) Which cranial nerves synapse in #3? Is the information processed here motor, sensory, or both?

 

 

Cranial nerve nuclei #4

1- Spinal trigeminal nucleus (V)

2- Spinal trigeminal tract (V)

3- Solitary nucleus and tract (VII, IX, X)

4- Dorsal motor nucleus of vagus (X)

5- Hypoglossal nucleus (XII)

6- Vestibular nuclei (XIII)

7- Cochlear nuclei (XIII)

Sample slide questions:

1) Where do the fibers that synapse in #7 originate? What is the destination of neurons that have their cell bodies in these nuclei?

 

 

 

Cranial nerve nuclei #5

1- Spinal trigeminal nucleus (V)

2- Spinal trigeminal tract (V)

Sample slide question:

1) Is the information processed in #6 motor, sensory, or both?

 

Cranial nerve nuclei #6

1- Spinal trigeminal nucleus (V)

2- Spinal trigeminal tract (V)

6- Vestibular nuclei (XIII)

7- Cochlear nuclei (XIII)

 

 

Cranial nerve nuclei #7

8- Mesencephalic trigeminal nucleus (V) 9- Trigeminal nerve (V)

Sample slide question:

1) What specific type of information, and from where, is carried by neurons that synapse in #8?

 

Cranial nerve nuclei #8

8- Mesencephalic trigeminal nucleus (V) 10- Oculomotor nucleus (III)

Sample slide questions:

1) Which eye muscle(s) are controlled by the oculomotor nerve?
2) What is the name of the other nucleus that receives axons from the third cranial nerve? What type of information is sent to this nucleus, and from where?
