Info How Are The Intervertebral Discs Innervated?

Why produce nosotros experience hurting inwards the cervical percentage inwards illustration of a herniated disc? Shouldn't the symptoms move solely inwards the affected dermatome (paresthesia, anesthesia too radiating pain) and/or myotome (muscle weakness or paralysis)? This was the inquiry I has too I read well-nigh the meningeal branches of spinal nerve.

After emerging from the intervertebral foramen, each spinal nervus gives off a small-scale meningeal branch which reënters the vertebral canal through the intervertebral foramen too supplies the vertebræ too their ligaments, too the blood vessels of the medulla spinalis too its membranes. The spinal nervus thence splits into a posterior or dorsal, too an anterior or ventral division, each receiving fibres from both nervus roots.
