Detailed explanation-1: -The vertebral foramen houses the spinal cord and its meninges. This large tunnel running up and down inside all of the vertebrae contains the spinal cord and is typically called the spinal canal, not the vertebral foramen.

Detailed explanation-2: -The spinal cord is a long, tube-like band of tissue. It connects your brain to your lower back. Your spinal cord carries nerve signals from your brain to your body and vice versa.

Detailed explanation-3: -Cauda equina: The spinal cord ends about three fourths of the way down the spine, but a bundle of nerves extends beyond the cord. This bundle is called the cauda equina because it resembles a horse’s tail. The cauda equina carries nerve impulses, both motor and sensory, to and from the legs.

Detailed explanation-4: -Each vertebra has a hole in the center, so when they stack on top of each other they form a hollow tube (spinal canal) that holds and protects the entire spinal cord and its nerve roots.
