The sign suggests a lesion of the dorsal columns of the cervical cord or of the caudal medulla.
If the upper cervical cord is involved, all four limbs may be involved and there is risk of respiratory paralysis (segments C3,4,5 to diaphragm).
Progressive tissue loss and injury occur in the cervical cord of MS patients.
The spinal accessory nucleus lies within the cervical spinal cord (C1-C5) in the ventral horn.
This loss results in hindbrain herniation and causes major compression of the upper cervical spinal cord.
The tumor may contiguously involve the cerebellar peduncles, cerebellum, the cervical spinal cord, and/or thalamus.
The subject was a 37-year-old male who suffered an injury to the cervical spinal cord 17 years prior.
In the course of conduction, the sensory fibers then transverse the cervical roots and enter the cervical cord.
Information from the neck and the back of the head is represented in the cervical cord.
Briefly, transverse sections of cervical and thoracic cord (50 μm) were cut with a vibratome.
