Doctor insights on:
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
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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

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 moreSee 1 more doctor answer
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
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?
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 moreSee 1 more doctor answer
