Nerves

Nerves are thread-like structures that form a network of pathways that transmit information from the brain to the body and the body to the brain, in the form of electrical impulses.

What is the effect when the neuron will not fire?

Then the signal will not be sent. The entire chain leading from the CNS to wherever it's going will be disturbed and will come to a halt.

What would happen if the heart did not have nerve tissue?

The muscles in the heart respond to an electrical stimulus to contract (beat). If there were no nerve tissue, the heart would not beat and a person would cease (or fail) to exist. Failure of the nerve stimuli, if nerve tissue is there (but for whatever reason there is a malfunction of the signal getting to where it needs to be), results in a condition called "Heart Block" and that can necessitate the implantation of a Pacemaker to produce the missing electrical stimulus constantly or intermittently as needed.

What ability do neurons have that other cells don't?

Cells other than neurons undergo apoptosis and if neurons die they don't regenerate hencw their number reduces and even their injuries are difficult to treat and it can cause several neurological diseases unlike other cells .

Do pinched nerves cause bumps on your back?

Yes. A pinched nerve can cause a muscle to contract. The "bump" that can be felt is actually the center of the tightened muscle. Massage may be used to relax the muscle. Relieving the pinched nerve is of course the better answer.

What causes a constant 'pins and needles' sensation down left arm?

You should always see your doctor with these symptoms. Most of the time it's stress through the neck and shoulder area and when under stress the muscles freeze up (like a knot.) A good soak in the tub with Epsom Salts will certainly help, and rub your neck and shoulders well with A535. If you are still having this problem then please see your doctor immediately.

If the pins and needles go along with a heavy chest or jaw pain call 911! It may be due to anxiety due to stress (many patients think they are having a heart attack and it turns out to be anxiety.) It's better to be safe than sorry.

NumbnessNumbness and tingling and parasthesia on the left side of the body means that there may be an abnormality in the right side of the brain.It can be a neurological pathology like motor neuron disease,TIA or stroke or autoimmune condition like multiple sclerosis in which the immune system attacks the central nervous system (CNS), leading to demyelination.It can be diagnosed by MRI brain and MRS of the brain.

Other possibilities are vit B12 deficiency,diabetes, hypothyroidism, hypoparathyroidism or peripheral nerve trauma or compression.

If tingling is there only on the left half of the body,it means a right side pathology of the brain.So I feel that clinical evaluation from a neurologist is necessary to rule it out.

What is oculomotor synkinesis?

nerve sprouts accidentally misdirect nerve transmission, so that efforts to utilize certain muscle groups accidentally prompt the functioning of other muscle groups.

Can rheobase be a threshold stimulus?

Yes, it can be because threshold and rheobase both are the voltage required to generate an action potential. The difference lies in that the treshold can be a voltage higher than rheobase.
