Detailed explanation-1: -The brain is superior to the spinal cord. The brain is the organ located at the top of the body and the spinal cord extends down from the base of the brain. Because the brain is located above the spinal cord, it is described as superior. The spinal cord is then inferior to the brain.

Detailed explanation-2: -The brainstem is the lower extension of the brain, located in front of the cerebellum and connected to the spinal cord. It consists of three structures: the midbrain, pons and medulla oblongata. It serves as a relay station, passing messages back and forth between various parts of the body and the cerebral cortex.

Detailed explanation-3: -As the spinal cord terminates at the L1-L2 level, other segments of the spinal cord would be positioned superior to their corresponding bony vertebral body. For example, the T11 spinal segment is located higher than the T11 bony vertebra, and the sacral spinal cord segment is higher than the L1 vertebral body.

Detailed explanation-4: -The spinal cord is a central nervous system structure that extends inferiorly from the brain stem and into the lower back. Throughout its length, it is enclosed within the spinal column, with the cord passing through the vertebral foramen of the vertebrae.
