Neural canal

Neural Canal is a significant structure in the vertebral column of vertebrates, including humans. It is a hollow passage running longitudinally within the vertebrae, providing a protective conduit for the spinal cord.

Anatomy

The neural canal is formed by the vertebral foramen of individual vertebrae aligning to create a continuous passage. The canal's size and shape can vary depending on the species and the specific vertebrae. In humans, the canal is larger in the cervical and lumbar regions, accommodating the increased size of the spinal cord in these areas.

Function

The primary function of the neural canal is to protect the spinal cord, a crucial part of the central nervous system. It also provides a pathway for spinal nerves to exit the spinal cord and reach the rest of the body.

Clinical Significance

Abnormalities or injuries to the neural canal can lead to serious medical conditions. For instance, a narrowed neural canal, a condition known as spinal stenosis, can compress the spinal cord or spinal nerves, causing pain, numbness, or weakness. Treatment for such conditions can range from conservative management to surgical intervention.
