It starts at the axonal hillock and it propagates down the axon into the terminal boutons.

What was Excitation and Inhibition about?

Excitation and Inhibition occur in the neurons. Excitation is when a neuron becomes depolarized and fires an action potential. Inhibition is when a neuron becomes hyperpolarized preventing it from firing an action potential.


When does a postsynaptic potential occur?

A postsynaptic potential occurs when neurotransmitters released from the presynaptic neuron bind to receptors on the postsynaptic neuron, causing a change in its membrane potential. This change can be either depolarizing (excitatory) or hyperpolarizing (inhibitory), influencing the likelihood of the postsynaptic neuron firing an action 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.


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.


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.


Why does hyperpolarization cause a spike to occur?

Hyperpolarization causes a spike to occur because it increases the difference in electrical charge between the inside and outside of a neuron, making it more likely for the neuron to generate an action potential or spike.


What happens during an action potential in a neuron?

During an action potential in a neuron, there is a rapid change in electrical charge across the cell membrane. This change allows for the transmission of signals along the neuron.


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.


When an action potential reaches the end of a neuron it triggers the release of?

neurotransmitters from the synaptic vesicles into the synapse. These neurotransmitters then bind to receptor proteins on the adjacent neuron, initiating a new action potential in the postsynaptic neuron.


What determines if an action potential is initiated in the postsynaptic neuron?

Every time neurotransmitter is released from the presynaptic neuron it generates an excitatory post synaptic potential(EPSP) in the postsynaptic neuron. When the EPSP is greater than the threshold for excitation an action potential is generated.


The fundamental cell type that conducts an action potential in the nervous system is a?

neuron


What changes occur in the neuron during an action potential?

During an action potential, the neuron undergoes a rapid change in membrane potential as sodium ions rush into the cell, leading to depolarization. Subsequently, potassium ions move out of the cell, repolarizing the membrane back to its resting state. This rapid change in membrane potential allows for the transmission of electrical signals along the neuron.
