Spinal Cord

No, that is a myth.

Spinal instrumentation is a method of straightening and stabilizing the spine after spinal fusion, by surgically attaching hooks, rods, and wire to the spine in a way that redistributes the stresses on the bones and keeps them in proper alignment.

Looking down on the involved levels (L5-S1), the top is toward your abdomen (NOON) and the back is toward the back (6 O'clock). I'll describe what happens, referring to times on the clock. Between each vertebra are thick disks: these comprise of a thick wall on the outside, filled with a thick gel. This acts as a "shock absorber". Nerves travel down the spinal canal as a thick cord of nerves and this cord is encased in a 3-layered sac, or envelope. Each nerve arises at a point in the brain, and travels down the cord, exits at its determined level and travels down the body to where it is designed to go/operate. Over the years these disks begin to wear out and flatten or possibly bulge out (like squashing a marshmallow). Sometimes, trauma --or bending or leaning with/without heavy lifting-- can cause a herniation in the side of this disk, and the resulting herniation can cause problems by pinching a nerve. If the herniation occurs at 5 o'clock or 7 o'clock, the herniation can pinch (trap) a nerve as it is preparing to leave the spinal cord and travel down the body, resulting in a severe burning pain and possibly muscle cramps if the nerve travels to the spasming muscle. If the herniation occurs at the NOON position, since no nerves (only blood vessels and bowel), there is no pain (actually, there can be pain, but it is not from nerves being pinched... there are pain fibers in the disk). If the herniation occurs at the 6 o'clock position no nerves will be trapped or pinched because there is a lot of space in the spinal canal where the spinal cord travels, but the sac surrounding the cord as it runs down the body CAN be indented. This is what the xray is describing, and there is nothing to worry about in this case...

I also wanted to know that information. I have had a spinal fusion at L5-S1. The answer is no. Any fusion surgery is a disqualifcation. I am bummed too:( Sorry!!!

ganglia

The basal ganglion are responsible for carrying the impulses from the cerebral cortex to the cerebellum. The impulses pass through the brain stem in an area called the pons where they cross-over and switch sides of the body. This is why your left side of your brain controls the right side, and visa versa.

The thin like membrane that covers the brain is "Dura Matter", and the thin like protection surrounding the spinal cord is a "mylein Sheath".

Dorsal is the medical term meaning back.

yes it can, paralysis will appear with any type of spinal cord injury

what is the pathological condition of the spinal cord

It's the part of the central nervous system.

unmyelinated axons.

The spinal cord extends from the brain stem to the coccyx. The exact length depends upon the individual, but it is something like a yard.

vocal cord differences in different genders include the following: size-women's smaller=higher pitch, men's bigger=lower pitch length-depends, male sizes=17mm-25mm, women sizes=12.5 mm-17.5mm tissue shape-can change sound!!!!! Yes. You can be born without vocal cords. It would be a birth defect.

Lumbar Enlargement

It's a plant fiber that by itself it weak, but can be woven together to make ropes.

a bundle of separete nerve

filium terminale

The vocal cords are capable of producing vibration in such a way as to create sound (and song!)

A "spinal tap" is also known as a "lumbar puncture".
Lumbar puncture

997.00.. this is the code for traumatic brain injury. it is also the code for nervous system impairement

Nerve impulses pass from the brain down the spinal cord to other parts of your body. Damage the spinal cord, and parts of the body below the injury may be paralyzed. Injure the spinal cord at the neck, you may not be able to breathe, and you will die.
