Re: CNS mtniharika - 02-27-10 00:48 My answer is: e.
Lateral protrusion which are more common will first cause pain & stiffness of the neck .the pain often radiates to the scapular region & sometimes to the occiput. Cervical prolapsed disc does not involve multiple nerve roots but it affects a single nerve root which emerges above the corresponding vertebrae ie C5 nerve root is involved in case of C4/C5protrusion .

in the intervertebral disc between c4 and c5 vertebra is C5 : Results in potential loss of function at the shoulders and biceps, and complete loss of function at the wrists and hands

it affects a single nerve root which emerges above the corresponding vertebrae ie C5 nerve root is involved in case of C4/C5protrusion so spinal nerve C5will be affected
