It reduces the loss of critical nutrients from the cell, reducing metabolic waste

Electrotonic current can travel further without loss, before an action potential needs to be produced

Electronic current can travel further without loss so no action potentials need to be produced

It ensures there is no loss of any current at all during electronic flow of current down the neuron

It allows action potentials to be produced along the entire length of the neuron

comparable to the values recorded by trained neurologists 

twice as fast as values that would be recorded by trained neurologists 

faster than the values that would be recorded by trained neurologists 

slower than the values that would be recorded by trained neurologists 

is faster for a strong stimulus than for a weak stimulus.

is slower in a long nerve than in a short nerve of the same diameter.

occurs at a constant velocity along the length of a neuron.

decreases in rate as it is conducted along the axon.

is mainly by the flow of K⁺ and Cl^- ions along the axon.

Voltage-gated Na⁺ channels are balanced off by voltage-gated K⁺ and Cl^- channels

The Na⁺/K⁺ pump is triggered into action to prevent concentration gradients being lost

Of the Relative Refractory Period

Voltage-gated Na⁺ channels become refractory rapidly after opening

Voltage-gated K⁺ channels open

Our electrodes are not placed to record trans-membrane currents/voltages

Our filters are not appropriate

The ground electrode shorts all APs to ground

Cockroach neurons dont have APs

We have not amplified enough

the ulnar nerve has a larger diameter from elbow to wrist than from wrist to hand

of the longer length of nerve for the elbow stimulation

of not correcting for the same fixed neuromuscular junction delay

you are stimulating the fast ulnar at the elbow and the slow hypothenar at the wrist

the ulnar is myelinated from elbow to wrist but not from wrist to hand

Muscle fibres

A spinal nerve consisting of sensory and motor axons

A single sensory neuron

A single afferent neuron

A spinal nerve consisting of an afferent and an efferent neuron

is produced when the membrane potential is depolarized to 0 mV.

is the result of a transient increase in K⁺ permeability and Cl^- permeability.

is the result of a transient increase in Na⁺ permeability and a decrease in K⁺ permeability.

is associated with an increase in the electrical resistance of the nerve membrane.

is always of a fixed size regardless of the strength of the stimuli eliciting the action potential.

An unmyelinated, small diameter nerve

A myelinated, small diameter nerve

They would all have the same conduction velocity

A myelinated, large diameter nerve
