Which of the following cranial nerve is affected in Bell's palsy?

Option 2 : Cranial nerve VII

Concept:-

• Bell's palsy causes temporary paralysis of the facial muscles.
• Bell's palsy occurs when trauma occurs in the seventh cranial nerve (the nerve that controls the muscles of the face).
• In Bell's palsy, the face tends to droop to one side or, sometimes, to both sides.
• This condition occurs when inflammation temporarily puts pressure on the nerve that controls the muscles of the face.

• Symptoms of Bell's palsy appear suddenly and peak within 48 to 72 hours.
• Eye care is very important. Eyedrops, including artificial tears, soothe dry, irritated eyes. If the eyelid does not close, an eye patch may need to be applied to protect the eye from irritation and injuries.
