Damage to lower motor neurons can lead to muscle weakness, atrophy, and fasciculations due to the loss of direct connection between the spinal cord and muscles. Patients may experience decreased muscle tone and reflexes, resulting in flaccid paralysis. Additionally, the affected muscles may become incapable of voluntary movement, significantly impacting mobility and overall function.
What else can I help you with?
What is motor nueron disease?
When nerve damage effects a motor nerve, you have a motor neuron disease. It is also called neuropathy. For information on nerve damage repair go to www.realfoodnutrients.com/neu/home.htm
What effects do neurotransmitters from the neuron have on the next neuron?
The neurotransmitters from one neuron have direct effect on the next neuron. They are channels that are used to transmit messages in the nerves.
What is descending tract and one ascending tract in upper motor neuron and lower motor neuron?
central nervous system (CNS) is the descending tract and one ascending tract in upper motor neuron and lower motor neuron.
Is motor neuron disease the same as ALS?
no yes, it is Lower Motor Neuron Disease
What is the association between delayed speech and neuron damage?
aphasia
What happens if myelin sheath is damage?
Two things, 1, the conduction speed of the neuron will be reduced. 2, the neuron will be subject to 'activation' from extraneous sources.
A motor neuron and all the muscle cells that is stimulates are referred to as a motor and plate?
false, it would be a motor unit.
What about the diameter of the nerve fiber?
The smallest neuron is at .004mm. The longest neuron, which runs from the lower spinal cord to the big toe, is over a meter long!
Effects of lidocaine on nerves?
it prevents sodium channels from opening which removes a neuron's resting membrane potential
How many motor neurons are involved in the descending motor pathways?
two motor neurons are always involved in descending motor pathways. the upper motor neuron and the lower motor neuron.
What is the process by which axons of healthy neurons adjacent to damaged neurons grow new branches to make up for the damage?
The process is called axonal sprouting or collateral sprouting. When neighboring axons detect damage to a neuron, they send out new branches to form connections with the target neuron. This allows for the establishment of new pathways to compensate for the damaged neuron's function.
What is the concentration of sodium in a neuron?
The concentration of sodium inside a neuron is lower than outside due to the activity of the sodium-potassium pump. Specifically, the concentration of sodium ions is higher outside the neuron at around 145mM, compared to around 10-15mM inside the neuron.
