In adults, the spinal cord terminates at approximately the level of L1. The nerve roots then descend through a fluid sac containing cerebrospinal fluid and are referred to as the cauda equina ("tail of a horse").
The inferior boundary of the spinal cord typically ends at the level of the L1 or L2 vertebra in most adults.
Spinal cord therapy
The bundle of nerves that connects the brain to the rest of the body is the spinal cord.
As the spinal disc becomes less elastic, it can rupture. When the disc ruptures, a portion of the spinal disc pushes outside its normal boundary--this is called a herniated disc. When a herniated disc bulges out from between the vertebrae, the spinal nerves and spinal cord can become pinched. There is normally a little extra space around the spinal cord and spinal nerves, but if enough of the herniated disc is pushed out of place, then these structures may be compressed.
The neural tube develops into the vertebrate spinal cord. It forms early in embryonic development from a flat sheet of neural ectoderm that rolls into a tube, eventually differentiating into the brain and spinal cord.
The inferior boundary of the spinal cord typically ends at the level of the L1 or L2 vertebra in most adults.
The most superior boundary of the spinal cord is the foramen magnum.
Spinal cord......
The foramen magnum is the large opening at the inferior portion of the occipital bone that allows the spinal cord to connect with the brain. It acts as a passageway for the brainstem and spinal cord to communicate.

The inferior continuation of the pia mater to the coccyx is the filum terminale, a slender filament of connective tissue. It helps to anchor the spinal cord within the spinal canal and provides longitudinal support to the spinal cord.
dura pater
Tethered Spinal Cord is a condition where the spinal cord is attached to the spinal column and that causes the cord to become stretched.
