There are 7 cervical vertebrae and 8 cervical spinal nerves. This explains why you have 31 spinal nerves relative to the 30 vertebral bones.

How many pairs of spinal nerves are in the spinal cord?
There are 31 pairs of spinal nerves in the spinal cord.The human peripheral nervous system has 31 pairs of spinal nerves.31there r 31 spinal nerves in a body31There are 31 total spinal nerve pairs8 pairs are cervical nerves12 pairs are thoracic nerves5 pairs are lumbar nerves5 pairs are sacral nervesI know that only adds up to 30. I don't know what the other pair is.31 pairs
Why are there 31 pairs of spinal nerve yet you only have 30 vertebrae?
You have 33 vertebrae. (8) Cervical, (12) Thoracic, (5) Lumbar, (5) Sacral, (3) Coccygeal. However, the coccygeal only gives off 1 coccygeal n. 8+12+5+5+1 = 31 spinal nerves
What is the difference between the frog and human nervous system?
The brain and spinal cord of a human are protected by a triple layer of membranes called meninges; the meninges of the frog have only 2 layers. Human brains are more developed that those of amphibians and contain a cerebral cortex which the frog lacks. A human has 30 pairs of spinal nerves, while a frog has only 10.

What symptoms would be caused by a small posterior midline disk herniation at c5 and 6 With a mild narrowing of the left neural foramen at this level secondary to uncinate process hypertrophy?
Many patients with back pain, leg pain, or weakness of the lower extremity muscles are diagnosed with a herniated disc. When a disc herniation occurs, the cushion that sits between the spinal vertebra is pushed outside its normal position. A herniated disc would not be a problem if it weren't for the spinal nerves that are very close to the edge of these spinal discs.The spinal disc is a soft cushion that sits between each vertabrae of the spine. This spinal disc becomes more rigid with age. In a young individual, the disc is soft and elastic, but like so many other structures in the body, the disc gradually looses its elasticity and is more vulnerable to injury. In fact, even in individuals as young as 30, MRIs show evidence of disc deterioration in about 30% of people.As the spinal disc becomes less elastic, it can rupture. When the disc ruptures, a portion of the spinal disc pushes outside its normal boundary--this is called a herniated disc. When a herniated disc bulges out from between the vertebrae, the spinal nerves and spinal cord can become pinched. There is normally a little extra space around the spinal cord and spinal nerves, but if enough of the herniated disc is pushed out of place, then these structures may be compressed.When the herniated disc ruptures and pushes out, the nerves may become pinched. A herniated disc may occur suddenly in an event such as a fall or an accident, or may occur gradually with repetitive straining of the spine. Often people who experience a herniated disc already have spinal stenosis, a problem that causes narrowing of the space around the spinal cord and spinal nerves. When a herniated disc occurs, the space for the nerves is further diminished, and irritation of the nerve results.SymptomsElectric Shock PainPressure on the nerve can cause abnormal sensations, commonly experienced as electric shock pains. When the compression occurs in the cervical (neck) region, the shocks go down your arms, when the compression is in the lumbar (low back) region, the shocks go down your legs.Tingling & NumbnessPatients often have abnormal sensations such as tingling, numbness, or pins and needles. These symptoms may be experienced in the same region as painful electric shock sensations.Muscle WeaknessBecause of the nerve irritation, signals from the brain may be interrupted causing muscle weakness. Nerve irritation can also be tested by examining reflexes.Bowel or Bladder ProblemsThese symptoms are important because it may be a sign of cauda equina syndrome, a possible condition resulting from a herniated disc. This is a medical emergency, and your should see your doctor immediately if you have problems urinating, having bowel movements, or if you have numbness around your genitals.All of these symptoms are due to the irritation of the nerve from the herniated disc. By interfering with the pathway by which signals are sent from your brain out to your extremities and back to the brain, all of these symptoms can be caused by a herniated disc pressing against the nerves.

When do humans begin to shrink?
Humans typically begin to shrink in height around the age of 40, with the rate of shrinking increasing as they get older. This shrinking is primarily due to age-related changes in the spinal discs and vertebral bones.

If you have 206 bones and 22 skull bones what percentage of human bones are skull bones?
The human skeleton has 206 bones and the human skull has 22 bones. The percentage will be: 22/206*100=10.67961165% OR it can be: 30/206*100= 15% (depending on the amount of human skull bones)
