Which ion has greatest influence on resting membrane potential? Potassium (potassium has more leak channels on the membrane than sodium, which is why potassium has a higher permeability value and has more impact of resting membrane potential) Concerning resting membrane potential, the inside of the membrane is _______ compared to the ________ charged outside. negative, positively. T or F: The diffusion of K+ and Na+ down their chemical gradients contributes to the resting membrane potenti...

effector proteins Ans: proteins that have some direct effect on the behavior of the target cell excitable dendrites Ans: Boosts EPSPs EPSP summation Ans: a simple form of synaptic integration whereby excitatory postsynaptic potentials combine to produce a larger postsynaptic depolarization synaptic integration Ans: process by which multiple synaptic potentials combine within one postsynaptic neuron voltage gated channels Ans: open and close in response to changes in membrane potential...

Chapter 7 1. What is action potential (AP)? - correct answer the form of electrical signals called action potentials (AP), which are rapid changes in membrane potential during which the inside of the cell becomes positively charged. (-100mV) From the negative to the positive. 1. Where does an AP originate and travel to? - correct answer Originates in the axon hillock and travels to the axon terminal. 2. Define leak channels and their locations. - correct answer • Always open (non-gated)...
