No. Other structures are affected too.
The 7th Cranial nerve (VII),
the nerve affected during Bell's Palsy, supplies more than just the
muscles of the face.
It also supplies the stapedius muscle which regulates the
tension on the bones of the middle ear and so may affect
hearing.
Also supplied by the same nerve is the anterior (back part) two
thirds of the tongue thereby affecting taste.
Additionally, the 7th Cranial
nerve is involved in the parasympathetic systems of
salivation and lacrimation (saliva in the mouth
and tear formation in the eye). |
