Answer :
Final answer:
Prosopospasm is correctly defined as a facial spasm, involving involuntary contractions of the facial muscles, and not complete paralysis. The correct option is D .
Explanation:
The correct definition of prosopospasm is facial spasm. Prosopospasm refers to involuntary contractions or twitches of the facial muscles. It is distinct from facial paralysis, which is the loss of voluntary muscle movement in the face due to nerve damage, and can occur in conditions like Bell's palsy, where one half of the face may droop.
While paralysis indicates a complete loss of muscle function, a spasm is more related to involuntary contractions and does not necessarily involve a total loss of muscle control or sensation.
