Once the membrane depolarizes come a height value that +30 mV, it repolarizes to its negative resting worth of -70 mV.

You are watching: Efferent nerve fibers may be described as motor nerve fibers.

The membrane potential need to depolarize from the relaxing voltage the -70 mV come a threshold value of -55 mV.

depolarizing currents developed by the influx of Na+‎ circulation down the axon and trigger an action potential in ~ the following segment

Why does regeneration of the action potential occur in one direction, fairly than in 2 directions?

The inactivation gates of voltage-gated Na+‎ networks close in the node, or segment, that has just fired an action potential.

The myelin sheath increases the rate of action potential conduction native the initial segment come the axon terminals.

Inactivation entrances of voltage-gated Na+‎ networks close, when activation gateways of voltage-gated K+‎ channels open.

Ions space unequally distributed across the plasma membrane of every cells. This ion distribution creates an electrical potential difference throughout the membrane. What is the name provided to this potential difference?

Sodium and also potassium ions deserve to diffuse across the plasma membranes of all cells because of the visibility of what kind of channel?

On average, the relaxing membrane potential is -70 mV. What walk the sign and also magnitude of this value tell you?

The resting membrane potential relies on two factors that influence the magnitude and also direction the Na+ and K+ diffusion throughout the plasma membrane. Determine these two factors.

Which of the following types of glial cell monitors the health of neurons, and also can transform right into a special type of macrophage to protect endangered neurons?

Which the the following are bundles of neurofilaments that are important in keeping the shape and integrity that neurons?

The period after an initial stimulus when a neuron is not perceptible to an additional stimulus is the ________.

A neuron that has actually as that primary duty the job of connecting other neurons is referred to as a(n) ________.

Which the the complying with is a aspect that identify the rate of impulse propagation, or conduction velocity, along an axon?

Which the the adhering to peripheral nervous mechanism (PNS) neuroglia form the myelin sheaths about larger nerve fibers in the PNS?

Neuroglia that control the chemistry environment roughly neurons through buffering ions such as potassium and also recapturing and recycling neurotransmitters are ________.

Which ion channel opens up in an answer to a readjust in membrane potential and participates in the generation and also conduction of activity potentials?

A neuron that has as that primary duty the job of connecting various other neurons is referred to as a(n) ________.

Which that the complying with circuit types is affiliated in the manage of rhythmic activities such together the sleep-wake cycle, breathing, and certain motor activities (such as eight swinging when walking)?

The __________ is as result of the distinction in K+ and Na+ concentration on either next of the plasma membrane, and the difference in permeability of the membrane to these ions.
