Question 1

what is the function of an axon terminal?

Accepted Answer

Transmission: The axon transmits the electrical signal from the nerve to the next nerve or a muscle through the neuromuscular junction.

Question 2

what is a axon test? how is it done?

Accepted Answer

Concussion test: It is a concussion test that can accurately diagnose concussion injuries.The test uses well known playing cards and measures reaction time and memory.

Question 3

what is the axon and what does it do?

Accepted Answer

Axon: Nerve fiber projecting from nerve cell (Neuron), conducting electrical impulses to send information to other neurons &amp; muscles &amp; glands.

Question 4

which diseases or disorders affect axons?

Accepted Answer

Numerous: If the axon affected is located in arms or legs, this is a peripheral neuropathy, if in spinal cord, perhaps a myelopathy, and brain and eyes, neuritis, encephalopathy.

Question 5

describe how a nerve impulse is transmitted along to axon?

Accepted Answer

It's complex: 1. Polarization of the neuron's membrane; 2. Resting potential gives the neuron a rest; 3. Action potential: sodium ions move inside the membrane; 4. Repolarization: potassium ions move outside, and sodium ions stay inside the membrane; 5. Hyperpolarization: more potassium ions are on the outside than there are sodium ions on the inside; 6. Refractory period puts everything back to normal.

Question 6

what are the symptoms of axon degeneration?

Accepted Answer

VARIES: Several peripheral neuropathies are considered "axonal" problems, and these include alcohol nutritional, diabetes, solvent poisoning, porphyria, amyloidosis, but small fibre axonal problems may be seen in sarcoid, sjogren's, lupus, paraproteinemias, celiac disease.  Symptoms include pain, numbness, weakness, inability to discern hot/cold.  Perhaps problems with balance.

Question 7

what is the role of the axon in learning and development?

Accepted Answer

Arms and legs: The neuron is the cell of the brain that is involved in learning and development. They need to be connected to other neurons to communicate. The axon is the arms or legs of the neuron that connect one neuron from another one. Without them, no communication and no learning and development.

Question 8

what is axonopathy of small cutaneous sensory axons? and what are treatments/prognosis?

Accepted Answer

Small fibre : When cutaneous small fibre nerves are afflicted, the patient loses pin and temperature sensation, but may develop widespread varying levels of pain, and punch biopsy shows low fibre density.  Not uncommon in diabetes, may be seen in immune neuropathies, and likely associated with porphyria, and alcohol problems.  Metanx may help, ivig in some.  Prognosis mixed.  May need neuromusclar specialist.

Question 9

if the immune system attacked killed the neurons cell body axons dendrites nerves throughout the body is it possible and what diagnosis would this be?

Accepted Answer

Complicated: This description is quite improbable and sounds as it the person may be deceased.  If you are having neurological deficiencies stronglysuggest that you see a neurologist and be evaluated.  Good luck.

Question 10

could lidocaine block the na channels at the ap or at the dendrites (before or after the axon hillock). is it possible an ap fires?

Accepted Answer

Nonspecific: Na channell blockade is a characteristic of lidocaine, that what allows it's use not only as a local anesthetic, but as antiarrhythmic agent as well. Although i must admit that i did not completely understand your question, the answer is yes, to my opinion. Hopefully you will be helped more by my colleagues, good luck.
