Where does the spinal cord end?
The spinal cord is an extension of the central nervous system (CNS), which consists of the brain and spinal cord. The spinal cord begins at the bottom of the brain stem (at the area called the medulla oblongata) and ends in the lower back, as it tapers to form a cone called the conus medullaris.
Does the spinal cord go through the sacrum?
There is no spinal cord in the sacrum region; however, sacral nerve damage in the sacral spine may have symptoms similar to spinal cord damage. Typically, with a sacrum injury or sacrum fracture: Injuries generally result in some loss of function in the hips and legs.

About the spinal cord and nerve roots
The spinal cord originates in the brain, exiting through a hole at the skull base called the foramen magnum and coursing through the spinal canal of the cervical, thoracic and upper lumbar spine before ending most commonly between the first and second lumbar vertebrae.
Does the spinal cord end at the coccyx?
The spinal cord terminates as the conus medullaris at the L1–L2 level in adults. Below this level, the cauda equina, composed of all lumbar, sacral, and coccygeal nerve roots, occupies the thecal sac. The lumbar nerves exit the intervertebral foramen under the pedicle of the same numbered vertebral body.
What happens if your spinal cord hurts?

What part of your spine controls your legs?
The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.
What is the gray commissure of the spinal cord?
a bundle of nerve fibers that surrounds the central canal of the spinal cord and connects the anterior and dorsal horns of gray matter in each half of the cord.
