Which cell must have action potentials to produce one or more action potentials in the postsynaptic cell?
A neuron (nerve cell) receives dendritic input in order to generate action potentials to transmit signals of the same. After the action potential triggers release of neurotransmitters in the axonal terminal of that neuron, those neurotransmitters propagate the signal forward to the next neuron, and so forth.
What do resting and action potentials depend on?
The resting and action potentials depend on the balance of charges of the area outside the neuron and inside the neuron. A resting potential is when the neuron is more negatively (approximately -70mv) charged than the area outside the neuron. The action potential occurs when sodium ions rush into the neuron, causing the polarity to be reversed. When there is no difference in charge between the area inside the neuron and the area outside the neuron, no action potentials can be started by that neuron.
What does communication in the nervous system depend on which are electrical impulses that travel from neuron to neuron?
action potentials
Action potentials originate at the?
Action potentials are how nerve impulses are transmitted from neuron to neuron. An action potential is formed when a stimulus to the nerve cell causes the membrane to depolarize and open all of its sodium ion channels toward the threshold potential.
How does an action potential differ from a graded potential?
Action potentials also known as spikes, differ from graded potentials in that they do not diminish in strength as they travel through the neuron.

What does communication in the nervous system depend on which are electrical impulses that travel from neuron to neuron?
action potentials
Does blocking receptors reduce action potentials?
Yes it reduces the chance of action potenctial to happen. The NMDA receptor is normally block be a Mg molecule. To unblock it the neuron must "fire" (generate action potencial).
Does nervous tissue generate action potentials?
Yes.
What is the electrical message that travels along a neuron?
electrical signal
Action potentials originate at the?
Action potentials are how nerve impulses are transmitted from neuron to neuron. An action potential is formed when a stimulus to the nerve cell causes the membrane to depolarize and open all of its sodium ion channels toward the threshold potential.
The area of the skin where stimulation generates action potentials in a particular sensory neuron is called that neuron's?
receptive field
How does an action potential differ from a graded potential?
Action potentials also known as spikes, differ from graded potentials in that they do not diminish in strength as they travel through the neuron.
Transmit neural messages from neuron to neuron?
Neurons send messages by way of chemical signalers called neurotransmitters. An activated neuron releases neurotransmitters and their collective action can stimulate another neuron. These individual firing sequences are called action potentials.
The first voltage-regulated gates encountered along the neuron membrane which initiate the formation of action potentials are located on the neuron near the?
axon hillock
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.
