During an action potential, what happens to the neuron's electrical charge?
During an action potential, the neuron's electrical charge rapidly changes from negative to positive, allowing for the transmission of signals along the neuron.
What happens to the neuron after an action potential is fired?
After an action potential is fired, the neuron goes through a refractory period where it cannot fire another action potential immediately. During this time, the neuron resets its electrical charge and prepares for the next signal.
What structure in the neuron accelerates the transmission of the action potential?
The structure in the neuron that accelerates the transmission of the action potential is called the myelin sheath.
What happens when an action potential reaches the nerve terminal?
When an action potential reaches the nerve terminal, it triggers the release of neurotransmitters into the synapse, which then transmit signals to the next neuron or target cell.
What happens when the action potential reaches the axon terminal"?
When the action potential reaches the axon terminal, it triggers the release of neurotransmitters into the synapse, which then bind to receptors on the neighboring neuron, continuing the signal transmission.

When you touch something hot a neuron in you finger senses the temperature which happens first?
an action forms
When you touch something hot a neuron in your senses the temperature. which happens first?
an action potential moves along the neuron
What is the interval called during which a neuron is dormant after an action potential has been completed?
Resting potential
What ion causes re polarization of the neuron during an action potential?
K+
In which direction do potassium ions flow as the action potential passes?
Potassium ions flow out of the neuron during the repolarization phase of the action potential, moving down their concentration gradient. This helps to restore the neuron's resting membrane potential.
What structure in the neuron accelerates the transmission of the action potential?
The structure in the neuron that accelerates the transmission of the action potential is called the myelin sheath.
Which is the first step in a neuron production of an action potential?
Depolarization is the first event in action potential. During depolarization, the sodium gates open and the membrane depolarizes.
What happens during the refractory period?
The voltage-gated Na+ channels get deactivated, thus the sodium ions cannot diffuse into the cell and cause depolarisation and this also provides time for the membrane to prepare for its second action potential.
When you touch something hot, a neuron in your finger senses the temperature. Which happens first?
an action potential moves along the neuron
When neuron stimulated enough it?
When a neuron is stimulated enough, it reaches its threshold potential and fires an action potential. This action potential travels down the axon of the neuron, allowing for the communication of signals to other neurons or cells.
