Variations
Since synkinesis is ultimately an interaction of nerves with muscles (although glands can also be involved), almost all studied cases are relevant to the cranial nerves where they interact with many small cranial muscles, most of which are responsible for separate and unique functions. This is in contrast to areas of our body where miswiring of the larger muscles is clinically less evident due the size of the muscles. The two cases of synkinesis most commonly studied involve the facial muscles and the extraocular muscles.

Famous quotes containing the word variations:
“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)
