Detailed explanation-1: -Neural canal in vertebra is the passage for spinal cord.
Detailed explanation-2: -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.
Detailed explanation-3: -In humans, the spinal cord begins at the occipital bone, passing through the foramen magnum and then enters the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae, where it ends.
Detailed explanation-4: -Neural Foramen The nerve roots travel through the foramen to reach the rest of your body. There are two neural foramina between each pair of vertebrae-one on each side. Without the foramen, nerve signals could not travel to and from the brain to the rest of your body.
Detailed explanation-5: -Each vertebra has an anterior arch and a posterior arch, which form a hole, called a foramen. The spinal cord passes through the foramen of each vertebra.
