Bell's Palsy is characterized by affecting which cranial nerve and typically presents with what feature?

Explanation:
Bell's Palsy is a peripheral problem with the facial nerve (cranial nerve VII), which controls most facial muscles. The hallmark feature is sudden weakness or paralysis of the facial muscles on one side of the face, leading to a drooped mouth and the inability to close the eye on the affected side. That unilateral facial weakness best captures what Bell's Palsy presents with. While the facial nerve does carry taste from the front two-thirds of the tongue, loss of taste isn’t the defining sign here. It isn’t caused by a brain tumor, nor is it a chronic degenerative condition.
