Bell's palsy is a paralysis in the face due to facial nerve :-
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Bell's palsy is indeed a paralysis in the face caused by the inflammation or compression of the facial nerve. This condition leads to the sudden weakness or inability to control the muscles on one side of the face, resulting in drooping of the eyelid, drooling, difficulty in closing the eye or smiling, and loss of taste. It is usually temporary and can be caused by viral infections, such as the herpes simplex virus. Treatment options include medication, physical therapy, and sometimes surgery.Rate this question:
