Step by step
Solved in 3 steps
- What are the three mainparts into which a neuron canbe divided? What are theirrespective functions?If the plasma membrane of an electrically excitable cellwere depolarized to threshold in the center of the axon orsarcolemma, would the action potential be propagated inonly one direction? Why or why not?If postsynaptic membrane permeability is increased, is theneuron more easily stimulated or less excitable?
- Distinguish between convergence and divergence in a neuronal pool.Which type of neuron, based on its shape, is bestsuited for relaying information directly from one neuron toanother? Explain why.Sometimes diverging circuits split into excitatory and inhibitory paths. When might such a circuit be required?
