What is an excitable nerve cell that sends electrical signals?
A neuron is an excitable nerve cell that sends electrical signals when stimulated
What behavior is observed if the voltage across a neuronal membrane is set to -20 mV?
If the voltage across a neuronal membrane is set to -20 mV, this would be closer to the threshold potential for neuron firing, leading to an increased likelihood of the neuron generating an action potential. At this level, the neuron is closer to depolarization and may be more excitable compared to when the membrane potential is at resting potential.
What happens when a neuron is stimulated by another neuron?
When a neuron is stimulated by another neuron, an action potential is generated and travels down the axon of the stimulated neuron. This action potential triggers the release of neurotransmitters at the synapse, which then binds to receptors on the postsynaptic neuron, leading to either excitation or inhibition of the postsynaptic neuron.
What is the basic function of a neuron?
Neurons are the basic building blocks of the nervous system and transmit signals between different parts of the body. They receive information from sensory organs, process it, and send out signals to muscles, glands, or other neurons. This allows for communication and coordination within the body.
What happens when a resting neuron's membrane depolarizes?
When a resting neuron's membrane depolarizes, it becomes more positive due to an influx of positively charged ions like sodium. This change in membrane potential triggers an action potential, leading to the propagation of electrical signals along the neuron.
What is an excitable nerve cell that sends electrical signals?
A neuron is an excitable nerve cell that sends electrical signals when stimulated
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 finger 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:
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.
How would you use the word excitable in a sentence?
He's just an excitable boy. She is too excitable to make a good soldier.
What is the adverb for excitable?
The word excitable is an adjective. The adverb form is excitedly.
