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.


Postsynaptic potentials can be excitatory and what else?

Postsynaptic potentials can be inhibitory as well. Inhibitory postsynaptic potentials (IPSPs) hyperpolarize the postsynaptic neuron, making it less likely to generate an action potential.


What is the time between the action potentials?

The time between action potentials is known as the refractory period, during which the neuron cannot generate another action potential. This period is essential to ensure that action potentials travel in one direction and allows the neuron to recover before firing again. The refractory period can vary but generally lasts around 1-2 milliseconds.


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.


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.

Why do action potentials propagate in one direction?

Action potentials propagate in one direction because of the refractory period, which is a brief period of time after an action potential where the neuron is unable to generate another action potential. This ensures that the signal travels in a linear fashion along the neuron and does not backtrack.


What cell that generates action potential?

Neurons are cells that generate action potentials. Action potentials are electrical signals that allow neurons to communicate with each other and transmit information throughout the nervous system.

What the Effect of ouabain drug on a neuron ability to generate action potential?

Ouabain blocks the Na+/K+ ATPase pump, preventing it from properly maintaining the Na+ and K+ gradients across the cell membrane. This disrupts the resting membrane potential and impairs the neuron's ability to generate 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.


The area of the skin where stimulation generates action potentials in a particular sensory neuron is called that neuron's?

receptive field


Corresponds to the period of repolarization of the neuron?

The period of repolarization of a neuron corresponds to the time when potassium ions move out of the neuron, allowing the cell to return to its resting potential. This phase follows the peak of the action potential when sodium channels close and potassium channels open, leading to membrane potential restoration. Repolarization is essential for the neuron to be able to generate subsequent action potentials.
