Final answer:
Hemiplegia is the term for muscular weakness or slight paralysis on one side of the body, often resulting from conditions such as stroke or brain injury.
Step-by-step explanation:
Muscular weakness or slight paralysis on the left or right side of the body is known as hemiplegia. This condition can result from various medical issues including stroke, brain injury, or diseases that affect the nervous system. In contrast to paraplegia which affects the lower part of the body, or quadriplegia which affects all four limbs and the torso, hemiplegia is characterized by paralysis on one side of the body. This can impact muscle function and mobility, sometimes accompanied by sensory loss, depending on the severity and location of the nerve damage.
