Listening to DIT right now and he gave a tip that (for example) if you have a weakness or whatever such as your RIGHT
soft palate is collapsed, then you need to work backwards and find all of the possible lesion sites.
- Pt. has a RIGHT sided soft palate weakness (ulna deviating to the left)
- RIGHT vagal nerve (CN X) innervates this area
- RIGHT nucleus ambiguus houses that nerve
- LEFT corticobulbar tract is theoretically the UMN
- LEFT motor cortex of the soft palate area sends the initial signal
I guess my question is: Besides the facial nerve (CN VII), do all MOTOR cranial nerves and their respective spinal nuclei function this same way?
(nuclei ipsilaterally, and motor cortex contralaterally)
Follow up question: Besides the facial nerve (CN VII), do the sensory pathways all follow a similar route?
(nuclei ipsilaterally, and sensory cortex contralaterally)
