@PaulBe - hi, a big thanks for the answer!
Can I ask you one more question, cause you seem to be familiar with the anatomy of ear - well, as I've lately written in this thread since my myoclonus began I'm able to move my eardrum voluntary. I was convinced I can move my tensor tympani muscle voluntary, but my ENT said it's impossible because no human being is able to move the tensor tympani muscle voluntary and consciously, whereas wikipedia claims following:
Tensor Tympani Muscle
Voluntary control
Contracting muscles produce vibration and sound.[3] Slow twitch fibers produce 10 to 30 contractions per second (equivalent to 10 to 30 Hz sound frequency). Fast twitch fibers produce 30 to 70 contractions per second (equivalent to 30 to 70 Hz sound frequency).[4] The vibration can be witnessed and felt by highly tensing one's muscles, as when making a firm fist. The sound can be heard by pressing a highly tensed muscle against the ear, again a firm fist is a good example. The sound is usually described as a rumbling sound. A very small percentage of individuals can voluntarily produce this rumbling sound by contracting the tensor tympani muscle of the middle ear. The rumbling sound can also be heard when the neck or jaw muscles are highly tensed as when yawning deeply. This phenomenon is known since (at least) 1884 (cf : Tillaux Paul Jules, Traité d'Anatomie topographique avec applications à la chirurgie, Paris Asselin et Houzeau publishers (4°ed. 1884, p. 125 )). source: http://en.wikipedia.org/wiki/Tensor_tympani_muscle).
Who is right? When not tensor tympani, which muscle can I move voluntarily? Tensor veli palatini or levator veli palatini?...
Have a nice day!
