Why is the sodium potassium pump important?
because without this pump the inside of neuron will stay + and outside -( check that, I am not that sure) and the neuron will not be able to function, as a result you will not feel any pain or even feel anything. read the section that talks about neuron's function...
What happens when bromine reacts with sodium?
Sodium bromide(NaBr) is formed
What happens when the body is lacking in sodium?
what causes a lack of sodium in the body
What happens when you mix sodium hydroxide with lactic acid?
sodium lactate
What happens if dilute sodium hydroxide enters your mouth?
Depending on concentration of NaOH, the quantity, the time of contact - benign or severe erosion of the mouth. NaOH is very dangerous for the skin. NaOH was used sometimes for killing or suicide.
What happens to the neuron if sodium channels do not open?
causes chemically gated sodium channels to open
How do non functional sodium channels affect the signaling capabilities of neurons?
When sodium enters the neuron, it depolarizes it. This means that the neuron becomes more positive. This can lead to the neuron reaching threshold and then initiate an action potential. When the sodium channels are NOT functional, the sodium can not enter and depolarize it. Therefore the threshold can not be met and action potential will not occur. If the sodium channels are inactive in an nociceptive neruon (carries information about pain), then the it will prevent you from feeling pain.
What molecularly happens a neuron affected by lidocaine?
Lidocaine is what is called an open sodium channel blocker. This means that it binds preferentially to sodium channels when they are in the open (letting sodium into the cell) state.
What happens when a resting neuron's membrane depolarizes?
If it is sufficiently depolarized it will fire an action potential A depolarized neuron will successfully pass a message. If you have a polarized neuron will not be able to feel a burn, etc.
The start of an action potential?
An action potential starts when sodium channels in a neuron end open and sodium ions rush is, depolarizing the neuron's membrane.
What happens at a synapses?
The transfers that happens in the synapses conduct biochemical information from the neuron cells. The synapse, or synaptic cleft is the gap between to neuron cells. Nerotransmitters are chemicals that are released from one neuron (known as the pre-synaptic) and bond to receptors on the receiving neuron (known as the post-synaptic). The transfers that happens in the synapses conduct biochemical information from the neuron cells.
What happens when you open the sodium channels in the membrane of a neuron?
When this occurs, the membranes potenial drops, as potassium and sodium diffuse with their gradient.
Why Sodium and potassium ion can only cross in axon membrane through protein channel explain why?
At rest sodium in the outside and potassium on the inside as action potential propagate along the axon, depolirization happens and sodium channel opens and allow sodium ions to flood into the neurone. A wave of deporization spread along the neuron, the neuron membrane contain specialised protein called channels. the channel from pore.
What happens when a neuron is polarized?
When a neuron is polarized, usually by the influx of chloride ions into the neuron, it is incapable of creating an action potential (incapable of firing). Only when the neuron returns to a resting potential, via pumping ions back across the membrane, can it be depolarized (sodium ion influx) to generate an action potential.
How are the sodium ions moved out of the neuron?
by "sodium pump", a process involving active transport
What occurs when sodium enters water?
When soidium enters water it forms a solution. The sodium would be the solute and the water is the solvent.
Why are sodium ions concentrated on the outside of the neuron?
get a book and find out
