Nerve supply of muscles in the head and neck
14 11 2007
Muscle group - nerve supply - except - which is supplied by
- Pharyngeal muscles - pharyngeal plexus (IX, X, sympathetic) - stylopharyngeus - IX
- Palatine muscles - pharyngeal plexus (IX, X, sympathetic) - tensor veli palatini - V3
- Laryngeal muscles - RLN (X) - cricothyroid - ext.br of superior laryngeal nerve (X)
- Tongue - XII - palatoglossus - pharyngeal plexus (IX, X, sympathetic)
- Mastication -V3 - buccinator - VII
- Facial expression and buccinator - VII
This “except - which is supplied by” is kinda fun to memorize, however i could only identify a clinical application for no. 3 in terms of a thyroidectomy.
2ndly, it did not come out in my exams. BEFORE you judge me on having a result-oriented / surface approach (Biggs model of learning) toward my education, we were assured that what’s important clinically will, should and must come out in the exams. Of course, in our limited foresight as students, we cannot always see the clinical significance of minutia.
If you are free to comment, please enlighten me.
[...] darn well is pretty fun, but i must still say, its overwhelming. It is. Just look at my previous post. Yes, the amount of anatomy we learn today is nowhere near what our predecessors learnt and [...]
Why does the picture show the cutaneous nerve supply but you talk about the muscle supply? Hah, sorry I’m bored so I’m being annoying.
More interestingly, why the the muscles associated with the middle ear supplied by different nerves? Stapedius by VII and tensor tympani by V3. The function of V3 supplying tensor tympani is obvious, but why stapedius? hmmm.
