Nerves in The Neck
Cranial Nerves and Spinal Nerves
Some of the nerves in the neck are the nerve fibres arising from the brain. In other words, they emerge directly from the brain. They are called as the cranial nerves as well. They are first part of the nerves in the neck. In the human beings there are traditionally 12 pairs of cranial nerves. Only the first and the second pair emerge from the cerebrum and the remaining 10 pairs emerge from brainstem. Each of the cranial nerve pair is also numbered and named. 1st cranial nerve is called as Olfaktorius nerve, the 2nd cranial nerve is called as Optic nerve, 3rd one is called as Okulomotor nerve, 4th one is called as Troklear nerve, 5th one is called as Trigeminus nerve, 6th one is called as Abdusens nerve, 7th one is called as Fasial nerve, 8th one is called as Vestibulokoklear nerve, 9th one is called as Glossofarinjikus nerve, 10th one is called as Vagus nerve, 11th one is called as Aksesorius nerve and 12th one is called as Hipoglossus nerve.
Spinal cord comes off the base of the brain, running throughout the thoracic spine and the cervical then ending at the part of the thoracic spine. Thus, spinal cord injury or damage is a very serious happening, may bring out serious trauma or diseases.
Spinal nerves emerge from segments of the spinal cord or medulla. There are 31 pairs of spinal nerves existing and they are the other part of the nerves in the neck. Among them 8 pairs take the name of since they emerge from neck level, 12 pairs emerge from the chest level of the spinal cord and take the name of chest spinal, 5 pairs take the name of waist nerve, 5 pairs take the name sacral nerves and 1 pair take the name of koksigol nerve.
There is no need to emphasize that nerves in the neck are very sensitive and needing a special care to from negative effecter conditions.
A herniated disc causes sometimes leg pain or arm pain. Arm pain from the herniation of a cervical disc is usually accompanied by tingling and runs to fingers.
Leg pain arising from a lumbar disc usually runs below the knee, possibly reaching to the foot.
