What condition is characterized by paralysis of all four limbs?

Quadriplegia, also known as tetraplegia, is characterized by paralysis of all four limbs, which includes both the arms and the legs. This condition typically arises from an injury or disease affecting the spinal cord in areas that control motor functions for all four extremities. The extent of paralysis can vary, with some individuals experiencing complete loss of motor control, while others may retain some function.

In contrast, hemiplegia refers to paralysis on one side of the body, often resulting from a stroke or brain injury. Paraplegia indicates paralysis of the lower limbs, usually stemming from a spinal cord injury affecting the lower sections of the spinal cord. Monoplegia involves paralysis of a single limb, commonly caused by localized issues, such as nerve injuries or specific neurological conditions. Therefore, quadriplegia is the term that accurately describes paralysis impacting all four limbs.
