Verified step by step guidance

Step 1: Understand the anatomy of a vertebra. A vertebra consists of several parts, including the body, spinous process, vertebral foramen, and transverse process. Each part has a specific function and structural role.

Step 2: Focus on the function of the vertebral body. The vertebral body is the large, cylindrical, anterior portion of the vertebra. It is designed to bear weight and provide structural support for the head, neck, and trunk.

Step 3: Compare the functions of the other parts of the vertebra. The spinous process serves as an attachment point for muscles and ligaments, the vertebral foramen houses the spinal cord, and the transverse process provides attachment points for muscles and ribs.

Step 4: Relate the weight-bearing function to the vertebral body. Since the vertebral body is the largest and most robust part of the vertebra, it is specifically adapted to support the weight of the head and trunk.

Step 5: Conclude that the vertebral body is the correct answer based on its structural design and primary function in weight-bearing.
