What does the term posterior refer to?

The term posterior refers specifically to a position on the body that is at or toward the back. In anatomical terminology, understanding directional terms like posterior is essential for accurately describing the locations of structures within the body relative to one another. For example, the shoulder blades are located posterior to the rib cage, meaning they are situated at the back side of the body.

Understanding the concept of posterior is foundational for nursing assistants, as it helps in providing proper care, positioning patients for examinations, and communicating effectively with other healthcare professionals. The other definitions do not align with the established anatomical terminology. For instance, 'above the body' describes a position in relation to height or elevation, while 'at or near the middle of the body' pertains to a central location, and 'below the waist' indicates a position relative to the waistline—not specifically toward the back.
