Myelinated axons are known to speed up the nerve impulse transmission. How does this happen?arrow_forwardIf the middle of an axon were depolarized to threshold, in which direction could the action potential propagate?arrow_forward
- The neurotransmitter secreted at an adrenergic synapse is _____________.arrow_forwardA damaged axon in the PNS may be able to regenerate only if the cell body is intact. why do you think that the cell body must be intact for regeneration to occur?arrow_forwardYou observe that a neuron treated with a metabolic inhibitor which prevents ATP generation still can generate action potentials even when the cell has little ATP, but the neuron eventually loses the ability to generate action potentials. What does this tell you about the direct mechanism for regenerating the resting potential after an action potential?arrow_forward
- A neurotoxin was delivered to a patient that prevented sodium channels from opening at the axon level. How does this affect a neuron's ability to communicate to other neurons? Explain in terms of action potential conductance, and neurotransmitter exocytosis at the axon terminal.arrow_forwardthe bacterium clostridium tetani produce a toxin called tetanospasmin, the causative agent os the disease tetanus. the toxin prevents the release of inhibitory transmitters in the CNS and so blocks the resulting IPSPs they would normally generate. what are some of the functions of inhibitory synapses? considering this what symptoms would you expect from the disease tetanus, and why?
