Excitatory synapses cause depolarization of the post-synaptic cell. - CORRECT ANSWER-True Excitatory synapses cause hyperpolarization of post-synaptic cells. - CORRECT ANSWER-False Excitatory synapses make the post-synaptic cell less likely to fire. - CORRECT ANSWER-False Fast neurons as described in lecture are fast because they are surrounded by a type of glial cell that results in a myelin coating. - CORRECT ANSWER-False The autonomic nervous system contains the sympathetic and the parasympathetic nervous system. - CORRECT ANSWER-True The axon hillock in the pre-synaptic neuron fires based on temporal and spatial summation of inputs. - CORRECT ANSWER-True Potassium ions are at high concentrations inside of cells including in neurons. - CORRECT ANSWER-True The receptors in post-synaptic cells are the basis on which the synapse can be defined as inhibitory or excitatory. - CORRECT ANSWER-False Acetylcholine e
