Facial neve (CN VII): Mimic musculature, parasympathetic influence, NOT the parotid
3 important questions on Facial neve (CN VII): Mimic musculature, parasympathetic influence, NOT the parotid
What sends a bilateral projection to the upper part of the Facial nucleus?
The cortex sends a bilateral projection:
- Only to upper part
- Of the Facial nucleus
- Resulting in contralateral face functioning
What happens to the upper part of the face after a stroke?
The upper part of the contralateral face still functions:
- Innervated by ipsilateral cortical tract
- Lower part of face shows paralysis
What is affected in a lower motor neuron lesion?
In a lower motor neuron lesion:
- The whole half of the face is affected
- Results in complete facial paralysis
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
