Neuron (Overview)

A neuron is a specialized cell that conducts impulses within the nervous system. It is made up of a cell body and processes including the axon and dendrites.

What do neurons do?

What do neurons do?

Neurons transmit sig: neurons transmits electric . They also process and transmit information between two cells. or introduce synapses, the specialized sites where neurons send and receive information from other cells, They also allow groups of neurons to coordinate complex processes.Without neurons, central nervous system does not function. Schwann cells lay down myliene around it which protects it and helps in fas ...Read more

Why are motor neuron diseases so dangerous?

Why are motor neuron diseases so dangerous?

No cure.: There truly is no effective treatment, and often, the bulbar musculature is afflicted causing both swallowing and breathing issues, which promotes early demise. Main issue, in most cases, is the preservation cognitive function, allowing patient to witness the devastation and anticipate problems. (variant associated with front-temporal dementia may be less intense) bad disease. ...Read more

What are the last stages of motor neurons disease?

What are the last stages of motor neurons disease?

Gruesome: Patient needs assistance with nutrition due to inability to swallow, and chokes on secretions, so a peg feeding tube is placed. Cannot breathe so a tracheostomy is employed. Infections overwhelm the system, and diffuse weakness or even paralysis from the muscle atrophy is present. But most patients intact cognitively and appreciate the catastrophe. Rather horrendous situation. ...Read more

Where are motor neurons found? What exactly do they do?

Where are motor neurons found? What exactly do they do?

Brain & spinal cord: Motor neurons provide connections for motor pathways which eventuate in our ability to move our muscles, walk and balance, and actively physically interact with our environment. This is simplistic as other nerve cells help refine and modulate all of these activities in a balanced fashion. ...Read more

What would happen if you somehow fused your neurons together?

What would happen if you somehow fused your neurons together?

Are you worried?: The separation of neurons by synapses is what makes it possible for the brain to do what it does, namely, think and control muscles. If you fused them all together your skull would contain a gigantic hard-boiled egg. Why do you ask? Are you afraid that it could happen or has happened to you? ...Read more

What are the tests used to diagnose upper motor neuron disorders?

What are the tests used to diagnose upper motor neuron disorders?

Clinical is the best: You've just stated a few hundred different disease processes that involve "UMN disorders." Which one did you have in mind? The best way to a diagnosis is a well trained neurologist who likes to examine their patients, judiciously use tests to help support their clinical thinking or help reorient them if necessary and not make snap decisions. Do you know anybody like that? That's who needs to see U ...Read more

What is the different between upper and lower motor neuron lesions?

Lesion Localization: The upper motor neurons also called “Cortical Motor Neurons” are located in the motor cortex of the brain. The the spinal motor neurons are the lower motor neurons. Signs of UMN is a stiffness and resistance to movement. Signs of LMN damage include weakness, muscle atrophy. Hope it helps. ...Read more
