Question

6|EXAM 2 44. The giant axon found innervating the muscle of the squid mantle is able to rapidly transmit nervous stimuli due to the fact that it A. has a higher than normal concentration of voltage gated Na+ and K+ channels in its axon B. has a larger diameter than most neurons, increasing the transmission rate of the signal C. has a higher concentration of Na'/ K pumps, allowing for increased rates of recovery from each stimulus event D.both b &c E. all of the above ncr in or the 45. When two excitatory stimulus events occur at a so rapidly in succession that after the first stimulus event the postsynaptic neuron's membrane potential has not returned to the resting potential before the

Answer 1

I think it should be be E. As a large diameter axon will increase the transmission due to less resistance to the ion movement and more conc of ion channels and better recvoery rates
