Verified step by step guidance

Understand the axial region: The axial region refers to the central part of the body, including the head, neck, and trunk. It houses several cavities that protect vital organs.

Identify the key term 'completely encased in bone': This phrase indicates that the cavity is surrounded entirely by bone, providing maximum protection to the organs within.

Review the dorsal aspect: The dorsal aspect includes the cranial cavity (housing the brain) and the vertebral cavity (housing the spinal cord). Both are completely encased in bone, such as the skull and vertebrae.

Compare with other aspects: The lateral, anterior, and ventral aspects contain cavities that are not entirely encased in bone. For example, the thoracic cavity (ventral aspect) is protected by the rib cage but not fully surrounded by bone.

Conclude that the dorsal aspect is the correct answer because it contains cavities (cranial and vertebral) that are completely encased in bone.
