Question

Quizplus · Accepted Answer

Locked-in syndrome is a condition in which a person is fully conscious but unable to move any voluntary muscles except the eyes due to damage to the central nervous system. Autonomic functions, such as heart rate and breathing, remain intact. Option A describes a panic attack or freeze response, where autonomic behaviors take over. Option C refers to apraxia, a condition in which an individual has difficulty performing new movements despite intact physical abilities. Option D is not an accurate description of locked-in syndrome since voluntary movements are impaired.
