1. Acon potenals normally travel along an axon toward the cell body. away from the cell body. in either direcon, depending on the needs of the animal. away from the synapse. from axons into dendrites. 5 points 1. A nerve impulse travels about me faster when it leaps between nodes of Ranvier than when it travels along an unmyelinated axon. 5 10 20 50 100 5 points 1. Which of the following statements about transmission across a typical chemical synapse is FALSE? Neurotransmier molecules are stored in vesicles in the synapc knob. Acon potenals trigger chemical changes that make the neurotransmier vesicles fuse with the plasma membrane of the transming cell. Vesicles containing neurotransmiers diﬀuse to the receiving cell's plasma membrane. Neurotransmier molecules bind to receptors in the receiving cell's plasma membrane. The binding of neurotransmiers to receptors opens ion channels in the membrane of the receiving cell. 5 points 1. Which division of the human nervous system carries signals to skeletal muscles? autonomic nervous system parasympathec nervous system somac nervous system sympathec nervous system sensory nervous system 5 points 1. The autonomic nervous system integrates sensory inputs to the brain. carries signals to and from skeletal muscles. regulates the internal environment of the body. is mostly voluntary. is part of the central nervous system. 5 points 1. When you are very nervous, perhaps before you must speak in front of a college class, you noce that your mouth is dry and your heart is racing. This is most likely due to smulaon by the enteric division of your autonomic nervous system. sympathec division of your autonomic nervous system. parasympathec division of your autonomic nervous system. All the choices are correct. None of the choices are correct. 5 points

1. The two major divisions of the nervous system are the ANS and SNS. sympathec and parasympathec. CNS and PNS. sensory and motor. voluntary and involuntary. 5 points 1. The division of the nervous system that integrates sensory informaon and coordinates the body's response is the: peripheral nervous central nervous system somac nervous system autonomic nervous system sympathec nervous system 5 points 1. Once the threshold potenal is reached the membrane potenal is posive. K+ channels open. Na+ channels close. an acon potenal is inevitable. None of the choices are correct. 5 points 1. Once an acon potenal is triggered, the ﬁrst major chemical change is a reversal of the membrane polarity, with the interior of the cell becoming posive. a reversal of the membrane polarity, with the interior of the cell becoming negave. an increase in the negave charges inside the neuron. a sudden rush of potassium into the neuron. a sudden impermeability of the membrane to the transport of ions. 5 points
