Bell's Palsy typically presents with weakness or paralysis on which part of the body?

• A. Whole body
• B. One side of the face
• C. Both sides of the face
• D. Limbs

Answer: (B)

Bell's Palsy is a peripheral facial nerve (cranial nerve VII) problem, so it causes weakness on just one side of the face. The facial nerve controls the muscles used to expressions and eyelid closure, so when it’s affected on one side you’ll see drooping of that entire facial half, including the forehead, eye, and mouth. This unilateral, whole-face involvement on one side distinguishes it from issues that affect the whole body or both sides, or from limb weakness. In contrast, a central stroke-type weakness often affects the lower face while sparing the forehead due to different nerve pathways, which is not the typical pattern in Bell’s Palsy.
