The terminal web correct answer: is a site of exocytosis The central nervous system (CNS) contains correct answer: There is no correct answer Acetylcholine exocytosed from the presynaptic cell travels to the postsynaptic cell to start the action potential in the postsynaptic cell 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 Voltage-gated ion channels open when a protein binds to the receptor correct answer: False The membrane potential (resting potential) is largely set by the Na-K-ATPase pump. correct answer: True Fast neurons as described in lecture require cytoplasmic signal transduction to open an ion channel. correct answer: False The post-synaptic cell can be correct answer: in glands, muscle cells, neurons 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 automatic nervous system contains the sympathetic and the parasympathetic nervous system correct answer: True Excitatory synapses make the post-synaptic cell less likely to fire. correct answer: False When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end plate correct answer: True Acetylcholine esterase breaks acetylcholine into muscarinic acid correct answer: False Receptors are made from membrane-bound polyribosomes. correct answer: True In the motor end plate, the event that is the immediate trigger for exocytosis is correct answer: Calcium ions
