Where do you find sympathetic nerve fibers in the head?
|
All fibers in the head are postganglionic from the superior cervical ganglion
|
|
|
How do the sympathetic fibers distribute in the head?
|
Periarterial Nerve Plexus
^Near the external/internal carotid arteries |
|
|
Which cranial nerves do parasympathetic nerve fibers ONLY innervate?
|
III, VII, IX, and X
We only typically see GVE fibers but IX and X have GVA (sensory) fibers as well. |
|
|
What do cranial nerves III, IV, and VI all have in common?
|
They innervate extraocular muscles which are used to move the eyeball. They all have GSE fibers in them.

|
1) Lacrimal
2) Submandibular 3) Sublingual Salivary |
|
|
True/False: The facial nerve provides taste from the tongue from the posterior 1/3?
