The neck is rich in nerves. The nerves related to cervical spondylosis include spinal nerves, cranial nerves and sympathetic nerves.

The cervical spine is the only way for nerve conduction. A sharp blow will block nerve conduction and cause fainting.

If the blow is too severe, the cervical spine will be deformed and the spinal cord will be damaged.

Severe spinal cord injury can cause paralysis of the lower limbs, incontinence of urine and feces, etc.

More serious cases can also cause death
