Anatomical regions refer to specific areas of the body that are used to identify and describe locations for medical and anatomical purposes. These regions help healthcare professionals communicate effectively about the body’s structure and function. Common anatomical regions include the head, thorax, abdomen, and limbs. Each anatomical region can be further divided into smaller areas for more precise identification. For example, the abdomen can be divided into quadrants, such as the right upper quadrant and left lower quadrant. Understanding these regions is essential for diagnosing conditions and planning treatments.
