Action potentials are conducted more rapidly when transmission is?
On a small diameter axon
What is a sequence of rapidly occurring events that decrease and reverse the membrane potential and then eventually restore it to the resting state?
Action potential or impulses
Where are taste impulses from?
Taste impulses are from a region in the brain called the primary gustatory cortex. The sense of taste is ultimately felt on various areas of the tongue where taste buds are present.
What major mineral is required for transmission of nerve impulses?
neuro transmitter is essential for the transmission of nerve impulses in nerve fibres.it is a chemical which is present in the axon terminal bulb(ending of a neuron).
What part in the nervous system moves?
Its the impulses sended from neuron to neuron via synapses... it can travel within a fraction of second which helps us to escape from dangers rapidly...
Are impulses conducted rapidly if neurotransmitters are present?
Myelin
Nerve impulses are conducted along an axon without decrement This means the action potentials are conducted without?
decreasing amplitude
Which is a very serious type of heart block in which no impulses are conducted to the ventricles?
third degree heart block
Why does increasing the axon diameter also increase the speed of impulse conduction?
Larger diameter axons conduct impulses more rapidly than axons with a smaller diameter. Larger axons tend to be myelinated and conduct impulses rapidly. Myelin is a substance rich in lipid that forms an electrical insulation layer around the axon. This insulating myelin sheath allows impulses to be transmitted more rapidly then small diameter axons that are nonmyelinated.
What is the present tense of conduct?
Conducted
Action potentials are conducted more rapidly when transmission is?
On a small diameter axon
Mechanism of nerve conduction?
Nerve impulses are conducted along the axon in the myelinated nerve fiber with causes the polarity of the nerve.
What is it called when small forces cause the amplitude of a wave to increase steadily?
If an oscillating object is subjected to small impulses of the same frequency as the object's natural frequency of oscillation, its amplitude will build up rapidly, depending on how much damping is present. This is caused resonance.
What is a sequence of rapidly occurring events that decrease and reverse the membrane potential and then eventually restore it to the resting state?
Action potential or impulses
At what speed are nerve impulses conducted in myelinated and unmyelinated neurons?
In thick well insulated (myelinated) neurones the impulse can travel in excess of 100m/s. In unmyelinated neurones the impulse can be conducted at less than 1m/s
