It depends on the person, but usually between cervical vertebrae C1 and C2 is where the brain ste ends and the spinal cord begins.
At the medulla oblongata.
brain stem?
Yes
no
The spinal cord ends at the level of the first lumbar vertebra, which is just below the level of the ribs.
Distal to the end of the spinal cord.
The cauda equina is the end of the spinal cord that fans out like a horse's tail.
the cauda equina is the nerve that emerges from the distal end of the spinal cord. it also supplies the lower extremities.
This means that there are no unusual findings or abnormalities in the distal cord of the spinal column. It suggests that the area at the end of the spinal cord appears normal and healthy on examination.
Syringomyelia is a disorder in which a cyst forms within the spinal cord. This cyst aka syrinx expands over time, destroying a portion of the spinal cord from its center and expanding outward.
filum terminale
conus medullaris
The spinal cord extends from the brain stem to the coccyx. The exact length depends upon the individual, but it is something like a yard.
The conus medullaris is the terminal end of the spinal cord. It occurs near lumbar nerves 1 (L1) and 2 (L2). After the spinal cord terminates, the spinal nerves continue as dangling nerves called the cauda equina. The upper end of the conus medullaris is usually not well defined.For the source and more detailed information concerning your request, click on the related links section (Answers.com) indicated below.
