Cervical Herniated Disc Herniated vertebral discs are also known
as slipped discs or bulging discs. Vertebral discs can prolapsed
or rupture into spinal canal causing radiating pain. When this

coughing, sneezing or other movements. The nerves in the neck
innervate the upper extremities. This may include: - Decreased
reflexes - Muscle atrophy of the biceps, triceps and muscles of
the forearm and hand
