Which term describes a condition limited to one side of the body?

The term that describes a condition limited to one side of the body is "unilateral." This term is commonly used in medical contexts to specify that an injury, condition, or disorder affects only one side, such as "unilateral weakness" in the case of a stroke, which may lead to symptoms on one side of the body. Understanding the term "unilateral" is crucial for healthcare providers when assessing patients and understanding the scope of various medical conditions.

In contrast, "bilateral" refers to conditions affecting both sides of the body, such as bilateral lung disease, where both lungs are involved. "Medial" describes a position closer to the midline of the body rather than indicating sides, while "symmetrical" generally refers to both sides being the same or having equal measure, which does not specifically denote a one-sided condition.
