Which option correctly lists the three classifications of paralysis?

• A. Hemiplegia, Paraplegia, Quadriplegia
• B. Paralysis, Encephalitis, Myelitis
• C. Hydrocephalus, Meningitis, Neuralgia
• D. Paralysis, Encephalitis, Myelitis

Answer: (A)

Paralysis is described by how much of the body is affected. The three common classifications are hemiplegia, paraplegia, and quadriplegia. Hemiplegia means paralysis on one side of the body, paraplegia means paralysis of the lower half (both legs), and quadriplegia (also called tetraplegia) means paralysis of all four limbs. This grouping specifically describes the extent and location of motor impairment, not the cause.

The other sets mix terms that are not classifications of paralysis. Encephalitis and myelitis are inflammatory conditions of the brain and spinal cord, hydrocephalus is buildup of fluid in the brain, meningitis is inflammation of the meninges, and neuralgia is nerve pain. These aren’t the ways doctors categorize paralysis. So the trio of hemiplegia, paraplegia, and quadriplegia is the correct listing.
