What term refers to paralysis of one side of the body?

The term that refers to paralysis of one side of the body is hemiplegia. This condition specifically indicates a total loss of movement and function in the limbs on one side, which can result from various medical issues such as stroke or brain injury. In hemiplegia, the paralysis affects either the right or left side of the body, while the other side remains unaffected.

Understanding the distinction between hemiplegia and related terms clarifies why this is the correct answer. Hemiparesis, for instance, refers to weakness rather than complete paralysis on one side of the body. Monoplegia denotes paralysis affecting a single limb, and paraplegia describes paralysis that affects the lower half of the body, typically involving both legs. Therefore, hemiplegia is the precise term for total paralysis of one entire side of the body, making it the correct choice.
