This week we went over the cranial nerves and how the autonomic nervous system is broken down into the parasympathetic and the sympathetic. There are 12 cranial nerves and each have its own function.
Cranial Nerves:
1. Olfactory is for smell and is a sensory nerve
2. Optic is for vision and is also a sensory nerve
3. Ocukomotor controls eye movement and pupil constriction. This is a mixed nerve.
4. Trochlear also controls eye movement
5. Trigeminal controls the face, teeth, and chewing
6. abducens controls eye movement and is a motor nerve.
7. facial nerve controls pressure and facial expression.
8. Vestubulo-cochlear controls hearing and balence
9. Glosso=pharyngeal, containing swallowing muscles
10. Vagus controls sensation from ear canal, diaphargm, and chest
11. axxessory contains muscles of palate, neck, and some shoulder muscles
12. Hypoglossal controls tongue movement.
Next week we have break. I will take this time and start preparing for our next class.

Carolyn,
ReplyDeleteI just wanted you to know that I had read all four of your blogs. It's great that you are making an effort to post each week, that should be very helpful to if you can continue with the same schedule when school resumes next week. Try to add a little bit more information from the research that YOU do on the internet each week to your blog postings...this is where you are demonstrating the applicability of this class to you and your life.
Keep this up! and Congratulations-you are 40 points richer!
