What else can I help you with?
What happens in the neurolemma as the result of an action potential?
It provides insulation to the axons and dendrites during depolarization or action potential.
Will a hyperpolarization graded potential lead to an action potential?
No, hyperpolarization graded potentials do not lead to action potentials. Hyperpolarization makes the membrane potential more negative, which inhibits the generation of an action potential by increasing the distance from the threshold potential needed to trigger an action potential.
What is the regeneration of action potential called?
The regeneration of action potential is called "propagation." It involves the transmission of the action potential along the length of the neuron's axon.
What transmission of the depolarization wave along the neurons membrane?
Action potential
Can subthreshold stimulation cause an action potential?
No, subthreshold stimulation is not sufficient to trigger an action potential. The membrane potential needs to reach a certain threshold level for an action potential to be generated. Subthreshold stimulation only produces graded potentials that do not reach the threshold for firing an action potential.
What happens in the neurolemma as the result of an action potential?
It provides insulation to the axons and dendrites during depolarization or action potential.
What happens to the heart when an action potential is generated in the SA node?
it contracts
When an action potential reaches an axon terminal, what happens to the neurotransmitters?
When an action potential reaches an axon terminal, it triggers the release of neurotransmitters into the synaptic cleft.
When an action potential reaches the nerve terminal, what happens to the neurotransmitter release?
When an action potential reaches the nerve terminal, it triggers the release of neurotransmitters into the synapse.
When substance is dipped in water the air comes out how it happens and what is the principle behind it?
Phenomenon of Capilary action or science of matter
What happens in the heart when an action potential is generated in the SA node?
Myocardial contraction
What happens to the neuron after an action potential is fired?
After an action potential is fired, the neuron goes through a refractory period where it cannot fire another action potential immediately. During this time, the neuron resets its electrical charge and prepares for the next signal.
What happens when an action potential reaches the nerve terminal?
When an action potential reaches the nerve terminal, it triggers the release of neurotransmitters into the synapse, which then transmit signals to the next neuron or target cell.
What happens during an action potential in a neuron?
During an action potential in a neuron, there is a rapid change in electrical charge across the cell membrane. This change allows for the transmission of signals along the neuron.
What happens when the action potential reaches the axon terminal"?
When the action potential reaches the axon terminal, it triggers the release of neurotransmitters into the synapse, which then bind to receptors on the neighboring neuron, continuing the signal transmission.
During an action potential, what happens to the neuron's electrical charge?
During an action potential, the neuron's electrical charge rapidly changes from negative to positive, allowing for the transmission of signals along the neuron.
When you touch something hot a neuron in you finger senses the temperature which happens first?
an action forms
