What else can I help you with?
The most rapid action potentials are conducted on?
The most rapid action potentials are conducted on myelinated axons, specifically those with a larger diameter. Myelination and a larger diameter help to increase the speed of conduction by decreasing capacitance and resistance.
What is most related to saltatory conduction dendrites or choroid plexus or nodes or ranvier or astrocytes?
Nodes of Ranvier are most related to saltatory conduction. These are gaps in the myelin sheath along the axon where action potentials are regenerated, allowing for faster conduction of electrical impulses. Saltatory conduction is the rapid jumping of action potentials between these nodes in myelinated neurons.
What is the route that results in the most rapid action of a drug?
Injection tends to lead to the most rapid action of drugs.
Where do most action potentials originate?
Action potentials most commonly originate in the axon hillock of a neuron, which is located near the cell body. This region has a high density of voltage-gated ion channels that are responsible for generating and propagating the action potential down the axon.
Why are most action potentials generated in response to a long stimulus that is above threshold?
Action potentials are generated in response to a long stimulus above threshold because it allows for the full development of the depolarization phase. This prolonged depolarization leads to the activation of voltage-gated sodium channels, triggering the rapid influx of sodium ions and initiating the action potential. A sustained stimulus ensures that the membrane potential remains above threshold for a sufficient time to generate an action potential.
Where does an action potential start?
Action potentials are generated on a part of the neuron called the 'axon hillock' - the proximal most portion of the axon.
Is the Nernst potential of Sodium achieved during the action potential?
the Nernst potential of Sodium is +60mV. most action potentials do not reach +60mV at peak depoloarization. http://openwetware.org/images/thumb/a/a6/Action-potential.jpg/300px-Action-potential.jpg.png
Where do most local potentials happen?
Local potentials typically occur in the dendrites and cell body of a neuron. They involve small changes in membrane potential that do not reach the threshold for generating an action potential. These local changes in potential allow for signal integration and processing in the neuron.
What fibers are the most rapid nerve impulses conducted on?
These are nerves in animals. They include central and peripheral; peripheral include somatic and autonomic.
Where do action potentials occur?
Action potentials occur along the axon of a neuron, where the electrical signals are transmitted from the cell body to the axon terminals. The action potential is initiated at the axon hillock and propagates down the axon to trigger the release of neurotransmitters at the synapse.
