Nerve conduction velocities also tend to decrease as a person gets older. Slower conduction velocities may also be caused by injury or damage to a nerve (such as carpal tunnel syndrome) or group of nerves (such as Guillain-Barré syndrome or post-polio syndrome).

The speed is affected by 3 factors:

• Temperature – The higher the temperature, the faster the speed.
• Axon diameter – The larger the diameter, the faster the speed.
• Myelin sheath – Only vertebrates have a myelin sheath surrounding their neurones.

The speed of nerve conduction does not depend on the diameter of axon only rather it depends on the diameter of the nerve fibre. Conduction velocity is high in myelinated nerve fibre with the greater diameter. So, the given statement is false.

A neurologist is a specialist who treats diseases in the brain and spinal cord (the central nervous system), peripheral nerves (nerves connecting the brain and spine to the organs, like the lungs or liver), and muscles.

Is Neuropathy a Disability? Neuropathy can be considered a disability by the SSA. In order to qualify for Social Security disability benefits with neuropathy, you need to meet both the work and medical guidelines that are set by the SSA.

Advertisement. A nerve injury can affect your brain’s ability to communicate with your muscles and organs. Damage to the peripheral nerves is called peripheral neuropathy. It’s important to get medical care for a peripheral nerve injury as soon as possible.

Could it still be neuropathy? You can still have polyneuropathy with a normal EMG nerve conduction study. EMG nerve conduction studies can only assess large fiber polyneuropathy. Small fiber cannot be evaluated by EMG nerve conduction study, but it may be assessed by skin biopsy.

Answer: Damaged nerves cannot be seen on a regular X-ray. They can be seen on CAT scan or MRI, and in fact, MRI is recommended for examining details of the spinal cord. For example, MRI can demonstrate tumors of the spinal cord and nerves that extend from the spinal cord called nerve roots.

An MRI may show nerve entrapment, but it has limitations. It only shows narrowing when the MRI was taken, at one point in time. It cannot tell if the nerve was more severely pinched three weeks ago or how tightly the nerve is being pinched right now.

With regards to the peripheral nervous system, to my knowledge it is not possible to be seen directly with the naked eye — simply due to the extensive amounts of collagen (skin tissue), muscle and bone contained within our bodies that burrow the actual neural connections to them, as opposed to the bunched-up …
