Final answer:
The major regions of the body include the head and neck, upper limbs, thorax and abdomen, pelvis and perineum, and lower limbs. These regions have specific names to accurately describe their location and structure.
Step-by-step explanation:
In anatomy, the human body is divided into major regions. These regions include the head and neck, the upper limbs (arms), the thorax and abdomen, the pelvis and perineum, and the lower limbs (legs). Each region has specific names such as the cranial region, cervical region, brachial region, thoracic region, and so on. These terms help anatomists accurately describe the location and structure of different body parts.
