Optic nerve crushed, optic nerve transplant?

Optic nerve crushed, optic nerve transplant?

No recourse: A crushed optic nerve (how did this happen to you?) causes permanent changes which will alter the vision sometimes severely. There is currently no treatment known for this and a transplant is not possible. A discussion with a neuro-ophthalmologist would be helpful in this situation. ...Read more

Will left bundle branch block cells regenerate?

Will left bundle branch block cells regenerate?

Usually not: Left bundle branch block (lbbb) develops when 2/3 electrical "wires" in the heart stop working. Many patients can have lbbb and no sx. Lbbb usually reflects aging of the heart but can be seen in a variety of pathological heart conditions. Rarely, medicines which affect the speed of electrical conduction in the heart can cause lbbb which reverses. This technically not cellular regeneration. ...Read more

What exactly is axonal sensorimotor peripheral polyneuropathy?

What exactly is axonal sensorimotor peripheral polyneuropathy?

Answer: Description of a peripheral neuropathy that predominantly affects the axon, wire within nerve, and secondarily affects the myelin, insulation. This characteristically occurs in diabetes, alcohol nutritional problems, porphyria, solvent exposure, amyloidosis, etc. ...Read more

What's protective myelin?

What's protective myelin?

Myelin Sheath: Myelin is the protective material that covers the axon of a neuron . The myelin forms a sheath which provides electrical insulation around the axon. ...Read more

Each peripheral nerve provides what innervation to peripheral structures.?

Each peripheral nerve provides what innervation to peripheral structures.?

Good question: I wish I could remember. When I have a question about that, I get out my old anatomy book from med school and look it up. The book is 1100 pages long. I refer to it frequently when I want to relearn what peripheral nerve innervates what structure. For laypeople I recommend Frank Netter's Atlas of Human Anatomy. It's available from Amazon. ...Read more

What is axonal peripheral neuropathy?

What is axonal peripheral neuropathy?

Axonal PN: Axonal peripheral neuropathy is an illness that may cause numbness and weakness affecting the feet, legs and sometimes the hands. In this condition the nerve cells (axons) that transmit information become ill. Common causes of this condition are hormonal and blood chemistry disorders...... http://www.ninds.nih.gov/disorders/peripheralneuropathy/detail_peripheralneuropathy.htm ...Read more

Does and EEG pick up brain stem neuron activity?

Does and EEG pick up brain stem neuron activity?

No: It does not pick up direct brainstem activity. Brainstem can modulate cortical ( surface of brain) activity which is what is seen on eeg. ...Read more

They say that carpal tunnel affects the nervous system. Is damage permanent?

They say that carpal tunnel affects the nervous system. Is damage permanent?

Can be: Carpal tunnel syndrome is a pinched nerve in the wrist that causes numbness and tingling in the fingers. This can lead to permanent nerve damage. The only way to know if there is permanent nerve damage is to take the pressure off the nerve and see how much of the the numbness and tingling improves. Nerve tests (emgs) can help but we'll not give you a definitive answer of permanent nerve damage. ...Read more

Can you tell me how the supporting cells of nervous tissue (e.g. schwann cells) differ from neurons?

Can you tell me how the supporting cells of nervous tissue (e.g. schwann cells) differ from neurons?

Brief anatomy: The nerve is comprised of a central axon, and larger fibers have an insulation covering called myelin. In the peripheral nervous system, the Schwann cell produces and maintains the insulation. Integrity of the nerve cell within the spinal cord provides the nutrition to maintain axonal function. ...Read more

Are NMDA receptors or ampa receptors found outside of the brain and spinal cord?

Are NMDA receptors or ampa receptors found outside of the brain and spinal cord?

Glutamate receptors: Glutamate is the major excitatory neurotransmitter in the cns, and could be expressed elsewhere in body, but the receptor description used above is designed to study brain pathways pre-dominantly, and has not be studied extensively othewise. Nmda antagonism is mechanism of several drugs, but to date, no successful ampa agonist. ...Read more

Is genitofemoral nerve a peripherel nerve?Ive read that peripherel nerves have striking capacity to regenerate.Though it takes time to heal true?

Is genitofemoral nerve a peripherel nerve?Ive read that peripherel nerves have striking capacity to regenerate.Though it takes time to heal true?

Yes: Ability to repair depends upon how much of the damage is just to the insulation of the nerve, vs. The "wire." a totally severed nerve generally cannot repair. ...Read more

What differentiates embryonic stem cells from other stem cells?

What differentiates embryonic stem cells from other stem cells?

Origin: Embryonic stem cells are derived from fertilized eggs created to help couples who have difficulty conceiving. This is "murder" according to some religionists. Other stem cells come from other sources. However, since the striking success of embryonic stem cells in early studies on wet macular degeneration, even the conservative presidential candidate no longer seems opposed to their use. ...Read more
