WorksheetsAnatomy 6.2 - Transmission of Nerve Impulses
Total questions: 11
Worksheet time: 6mins
In the resting phase of the axon during an impulse conduction, the outside of the axon has a positive charge while the inside of the axon has a negative charge. this resting state is also called -
polarized
insulated
depolarized
conductive
When a stimulus approaches the axon, it opens up channels to allow what chemical ion to flow into the axon?
sodium
iron
potassium
calcium
When the chemical ions enter the axon, the charges flip and the outside now becomes negative and the inside positive. This is known as -
polarization
conductivity
depolarization
insulation
To return back to the normal resting phase, a channel on the axon membrane opens up and allows what chemical ion to escape from the axon?
sodium
calcium
potassium
iron
Returning back to the resting phase is called -
polarization
conductivity
depolarization
repolarization
The time between the completion of the impulse and repolarization is called the -
polarization
refractory period
completion
impulse delay
The ability of a neuron (axon) to transmit a nerve impulse is called -
reflexes
polarization
depolarization
conductivity
When the action potential impulse is traveling down the axon and it "jumps over" the myleninated sections of the axon to make the impulse move faster, this is known as -
impulse momentum
electric current
saltatory conduction
nodes of Ranvier
Which of the following will be the slowest moving nerve impulse?
an axon covered with mylein sheaths (schwann cells)
a large diameter axon
an axon in warmer than normal temperatures
unmyleinated axons
This type of reflex involves the stimulation of skeletal muscles
somatic
parasympathetic
autonomic
sympathetic
This type of reflex is one where it sends involuntary stimuli to the cardiac muscle and smooth muscles of the internal organs.
somatic
parasympathetic
autonomic
sympathetic
