In a neuron impulses move?
In a neuron, impulses move through electrical signals known as action potentials. These action potentials are generated when a neuron receives enough stimulation to reach a threshold, causing a rapid change in membrane potential. The action potential then travels down the length of the neuron's axon until it reaches the next neuron or target cell.
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.
Where does an impulse move from on neuron to the other?
The impulse has to cross over a synapse to another neuron or an effector.
What effect does the opening of the potassium channels have on the charge difference across the neuron's membrane?
Opening of potassium channels allows potassium ions to move out of the neuron, leading to hyperpolarization by increasing the negative charge inside the neuron. This action increases the charge difference across the membrane, known as the resting membrane potential, making the neuron less likely to fire an action potential.
Do graded potentials increase amplitude as they move away from the stimulus?
No, graded potentials do not increase in amplitude as they move away from the stimulus. The amplitude of graded potentials will decrease with distance from the stimulus site due to the loss of charge.

How does electrical impulses move through the synapse gap?
Electrical impulses, or action potentials, do not directly move across the synaptic gap; instead, they trigger the release of neurotransmitters from the presynaptic neuron into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, leading to changes in the postsynaptic membrane potential. This process converts the electrical signal into a chemical signal and back into an electrical signal, allowing communication between neurons.
Will graded potential increase amplitude as they move away from the stimulus point?
No, graded potentials do not increase in amplitude as they move away from the stimulus point. They dissipate as they travel along the neuron membrane due to leak channels and distance from the original stimulus.
What effect does the opening of the potassium channels have on the charge difference across the neuron's membrane?
Opening of potassium channels allows potassium ions to move out of the neuron, leading to hyperpolarization by increasing the negative charge inside the neuron. This action increases the charge difference across the membrane, known as the resting membrane potential, making the neuron less likely to fire an action potential.
How does a signal move through a neuron?
A signal moves through a neuron by traveling along the axon, which is a long, thin extension of the neuron. The signal is transmitted as an electrical impulse called an action potential. When the signal reaches the end of the axon, it triggers the release of neurotransmitters, which then carry the signal to the next neuron.
Do graded potentials increase amplitude as they move away from the stimulus?
No, graded potentials do not increase in amplitude as they move away from the stimulus. The amplitude of graded potentials will decrease with distance from the stimulus site due to the loss of charge.
What is a small space across which an impulse travels to move from on neuron to another?
It's most likely called a synapse
A small space across which an impulse travels to move from one neuron to another?
It is most definitely a synapse.
What is A small space across which an impulse travels to move from one neuron to another?
Synapse. The gap itself is called the synapticcleft.
