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

neuron


What portion a neuron conducts nerve impulses away from the neuron?

axons


Is the axon the conduction component of a neuron?

Yes, the axon conducts the action potential from the cell body to the effector organ.


Where does an action potential start?

Action potentials are generated on a part of the neuron called the 'axon hillock' - the proximal most portion of the axon.


What parts of a neuron is capable of generating a graded potential?

The dendrites portion of a neuron will generate a 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.


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.
