ASU Bio 181 Quiz 4 Latest Update Graded A+ (T/F) Acetylcholine esterase breaks acetylcholine into muscarinic acid False (T/F) Acetylcholine exocytosed from the presynaptic cell travels to the postsynaptic cell to start the action potential in the postsynaptic cell. True (T/F) Excitatory synapses cause depolarization of the post-synaptic cell. True (T/F) Excitatory synapses cause hyperpolarization of post-synaptic cells. False (T/F) Excitatory synapses make the post-synaptic cell less likely to fire. False (T/F) Fast neurons as described in lecture are fast because they are surrounded by a type of glial cell that results in a myelin coating. False (T/F) Fast neurons as described in lecture require cytoplasmic signal transduction to open an ion channel. False (T/F) Insulin is a ligand. True (T/F) Insulin is produced by alpha cells. False (T/F) Only pre-synaptic neurons are coated with myelin. False (T/F) Potassium ions are at high concentrations inside of cells including in neurons. True (T/F) Receptors are made from membrane-bound polyribosomes. True (T/F) The autonomic nervous system contains the sympathetic and the parasympathetic nervous system. True (T/F) The axon from a pre-synaptic cell contacts the axon of another neuron. False (T/F) The axon hillock in the pre-synaptic neuron fires based on temporal and spatial summation of inputs. True (T/F) The cell body refers to the part of the neurons that begin at the dendrites and extend to the axon terminal. False (T/F) The medulla of the adrenal gland produces epinephrine (i.e., adrenaline). True (T/F) The membrane potential (resting potential) is largely set by the Na-K- ATPase pump. True (T/F) The Parasympathetic Nervous System is triggered is trigger to act by exposure to epinephrine. False
