the finger movements necessary to produce the "Vulcan salute" can only be made correctly with practice.

Examine the neuromuscular interactions that are responsible for this situation. How do the nerves, muscles, bones, and joints interact in making this hand sign in a way that is different from the unmodified (or unpracticed) movements of these structures in the hand? What has to be modified for a successful Vulcan salute?

Be sure to identify the muscles that contribute to these actions and the nerves that supply them, and to describe how the interactions of the nerves with the muscles, bones, and joints accomplish this phenomenon.
