A neuron which is excitable is in its RESTING STATE, which means that it is POLARIZED, and thus able to be stimulated into an action potential.

What is an excitable nerve cell that sends electrical signals?
A neuron is an excitable nerve cell that sends electrical signals when stimulated
What is the basic function of a neuron?
A neuron is an electrically excitable cell, that transmits signals (after processing) to another neuron or tissue. It sends out information to the brain.
An action potential is triggered if?
If a neuron, or other excitable tissue, is stimulated by a stimulus of threshold strength or greater strength..
How is the resting potential different from repolarization?
Repolarization is when the cell or neuron returns to be more negative. Depolarization is when the cell or neuron becomes less and less negative.
What part of a neuron would probably be affected most by the application of Novocain?
Novocain blocks calcium channels. Voltage-dependent calcium channels are a group of ion channels found in the membrane of excitable cells such as the axons of neurons and glial cells.

How does Frankenstein react when he returns to his apartment with Clerval and discovers the creature is gone?
he becomes excitable and act irrationally
Why does muscles have a refractory period?
it the period when an action potential cannot be elicited in an excitable cell(neuron,muscle cell etc.) after it has been excited.
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 you touch something hot a neuron in your senses the temperature. which happens first?
an action potential moves along the neuron
What happens when neurotransmitters communicate an excitatory message to the postsynaptic neuron?
When neurotransmitters communicate an inhibitory message to the postsynaptic neuron:
How is the resting potential different from repolarization?
Repolarization is when the cell or neuron returns to be more negative. Depolarization is when the cell or neuron becomes less and less negative.
What is the Neuron function?
The function of a neuron is to transfer messages throughout the brain. These neurons are all attached and interpret everything that happens.
When you touch something hot, a neuron in your finger senses the temperature. Which happens first?
an action potential moves along the neuron
When you touch something hot neuron in your finger senseds the temperature. Which happens first?
an action potential moves along the neuron
