Numbness in face and facial muscles
We have a lot of facial muscles. They are involved in all
kinds of chewing food, bright eyes, smile or frown. And the controller of these
muxcles is nerves, and if the nerves are not working properly, one or more of
three things can happen. The first is that the muscles can not function, and
another is that the numbness set in. This condition can be partial or total. In
most cases, stiffness or lack of muscle control is partial, because there is a
network of nerves extending face. Muscles where you feel numbness specially numbness in face, or if a
malfunction or not depends, of course, the nerves that are involved in this
network. The third thing, about tingling in the face and muscle control, is a situation where
the nerve can cause pain instead of numbness, facial pain, but beyond the scope
of this discussion.
There is a ridge on the base of the brain that controls the
network nerves of face. And it is sometimes we called the facial nerve, which
can be somehow terrible, and sometimes called the seventh cranial nerve, which
does not say much. The term most commonly used is the trigeminal nerve, which
branches into the network called facial nerves. If one of these branches damaged,
or the blood supply to a branch of the nerve is interrupted, partial facial
numbness and / or can cause paralysis. If the trigeminal nerve is damaged,
numbness and / or paralysis may be complete.
