Between vertebrae L1 and L2, the first part of the lumbar region which is the inward curvature in your lower back. The cord ends here and becomes the cauda equina which is latin for horses tail! It is called this because it looks like a horses tail as it splits into many fibers at this point and continues to descend down through the sacral part of the spinal cord.
Answer:
The Spinal Cord is connected to the brain and is about the diameter of a human finger. From the brain the spinal cord descends down the middle of the back and is surrounded and protected by the bony vertebral column. The spinal cord is surrounded by a clear fluid called Cerebral Spinal Fluid (CSF), that acts as a cushion to protect the delicate nerve tissues against damage from banging against the inside of the vertebrae.
The anatomy of the spinal cord itself, consists of millions of nerve fibres which transmit electrical information to and from the limbs, trunk and organs of the body, back to and from the brain. The brain and spinal cord are referred to as the Central Nervous System, whilst the nerves connecting the spinal cord to the body are referred to as the Peripheral Nervous System.
The nerves within the spinal cord are grouped together in different bundles called Ascending and Descending tracts.
