What condition is characterized by paralysis of all four limbs?

• A. Hemiplegia
• B. Quadriplegia
• C. Cerebellum Dysfunction
• D. Paraplegia

Answer: (B)

Quadriplegia is a condition that involves the paralysis of all four limbs due to injury or disease affecting the spinal cord or the brain. This type of paralysis typically occurs when there's significant damage to the spinal cord in the cervical region, which can result from trauma, such as a car accident or fall, or from conditions like multiple sclerosis or ALS.

In contrast, hemiplegia refers to paralysis on one side of the body, typically resulting from a stroke or brain injury. Cerebellum dysfunction affects coordination and balance but does not directly cause paralysis. Paraplegia involves paralysis of the lower limbs, resulting from spinal cord damage lower in the spine. Thus, quadriplegia specifically addresses the paralysis of both arms and legs, making it the correct choice for this condition.
