Which of the following terms refers to paralysis affecting all four limbs?

Quadriplegia specifically refers to the paralysis of all four limbs, which includes both the arms and legs. This condition is typically caused by an injury to the spinal cord at a cervical level, affecting the function of the nerves that control movement and sensation in the body below the injury site.

In contrast, hemiplegia denotes paralysis affecting one side of the body, often due to a stroke or brain injury. Paraplegia involves paralysis of the lower limbs, typically resulting from spinal cord injuries that affect the thoracic, lumbar, or sacral regions. Monoplegia refers to paralysis that affects only a single limb. Understanding these distinctions is crucial in medical terminology, as they relate to different types of neurological impairments and their underlying causes.
