If the Nodes of Ranvier were shortened (i.e. the sections of myelin were closer together), would action potentials move down the axon faster or slower? Why?
They would move slower because its longer to go from section to section then just straight through.
Node of ranvier is small gaps in myelin sheath of medullated axons

What is typically the role of an inhibitory synapse? to open Na+ channels in the post-synaptic membrane to depolarize the post-synaptic membrane to generate an EPSP to hyperpolarize the post-synaptic membrane If a post-synaptic nerve cell receives a large number of EPSPs from synapses on different dendrites, what is the most likely result? A hyperpolarization Mechanical summation Spatial summation An IPSP Why might natural selection have favored cephalization? It allows animals to better detect stimuli behind them, if they are...
Case 34 Emirates Airline Emirates Airline was one of the three Middle East carriers that were singled out by the largest US airlines in the report that was released on March 5, 2015. The report charged that that the flagship airline of Dubai, along with Etihad Airways and Qatar Airways, had received over $42 billion in government subsidies and tax breaks since 2004.
