What else can I help you with?
The depolarization of a neural membrane creates a?
The depolarization of a neural membrane creates an action potential, which is a brief electrical charge that travels down the axon of a neuron. This action potential is crucial for transmitting signals between neurons and ultimately forms the basis of communication in the nervous system.
What type of cell enhances the velocity of electrical transmission of an action potential along an axon in the peripheral nervous system?
Schwann cells enhance the velocity of electrical transmission of an action potential along an axon in the peripheral nervous system by forming a myelin sheath around the axon. This myelin sheath insulates the axon, allowing for faster conduction of the action potential through a process known as saltatory conduction.
Is action potential essential for impulse propogation?
Yes, action potential is essential for the propagation of impulses in neurons. It is the electrical signal that travels along the axon of a neuron, allowing the communication of information within the nervous system.
Circle the letter of the choice that describes an action potential?
An action potential is a rapid and transient change in membrane potential that travels along the axon of a neuron. It is characterized by depolarization, repolarization, and hyperpolarization of the cell membrane. The action potential is essential for transmitting electrical signals in the nervous system.
Disturbances when will sensory neurons result in an action potential?
Disturbances to sensory neurons can cause depolarization of the neuron's membrane, reaching a threshold that triggers an action potential. This action potential then travels along the neuron's axon to the central nervous system, where it is processed and interpreted as a sensory experience.
Which cell conducts an action potential?
neurons
Is action potential all or none?
In terms of the nervous system, yes.
What is the difference between generator potential and action potential in terms of their roles in the nervous system?
Generator potential is a small electrical signal that occurs in response to a stimulus, while action potential is a larger electrical signal that is responsible for transmitting signals along the nerve cell. Generator potential initiates the process of creating an action potential, which then allows for the transmission of signals within the nervous system.
Is the axon the conduction component of a neuron?
Yes, the axon conducts the action potential from the cell body to the effector organ.
What kind of potential is it when a neuron fires?
When a signal is sent out from the nervous system it is caused a release of a neurotransmitter that releases an action potential.
The cells in the nervous system that receive and send neurotransmitter messages?
impulses travel to and from the central nervous system allowing the brain and spinal cord to control all your other body systems
What is an action potential and how does it function within the nervous system?
An action potential is a brief electrical signal that travels along a neuron's membrane. It is generated when the neuron is stimulated and involves a rapid change in voltage. This signal allows neurons to communicate with each other and transmit information throughout the nervous system.
What is fundamental movement action in physical education?
an action for fundamental movement

What type of cell enhances the velocity of electrical transmission of an action potential along an axon in the central nervous system?
Oligodendrocyte
When an action potential passes through the central nervous system without going to the brain it is called a?
I believe that you are referring to a "reflex".
