9) In the communication between a motor neuron and a skeletal muscle, A) the motor neuron is considered the presynaptic cell and the skeletal muscle is the postsynaptic cell. B) the motor neuron is considered the postsynaptic cell and the skeletal muscle is the presynaptic cell. C) action potentials are possible on the motor neuron but not the skeletal muscle. D) action potentials are possible on the skeletal muscle but not the motor neuron. E) the motor neuron fires action potentials but the skeletal muscle is not electrochemically excitable.
16) Two fundamental concepts about the ion channels of a 'resting' neuron are that the channels A) are always open, but the concentration gradients of ions frequently change. B) are always closed, but ions move closer to the channels during excitation. C) open and close depending on stimuli, and are specific as to which ion can traverse them. D) open and close depending on chemical messengers, and are nonspecific as to which ion can traverse them. E) open in response to stimuli, and then close simultaneously, in unison.
36) One possible disadvantage to a nerve net is that it might conduct impulses in two directions from the point of the stimulus. Most of the synapses in vertebrates conduct information in only one direction A) as a result of the nodes of Ranvier. B) as a result of voltage-gated sodium channels found only in the vertebrate system. C) because vertebrate nerve cells have dendrites. D) because only the postsynaptic cells can bind and respond to neurotransmitters.
E) because the sodium-potassium pump moves ions in one direction. 40) The following steps refer to various stages in transmission at a chemical synapse. Neurotransmitter binds with receptors associated with the postsynaptic membrane. Calcium ions rush into neuron's cytoplasm.
An action potential depolarizes the membrane of the axon terminal. The ligand-gated ion channels open. The synaptic vesicles release neurotransmitter into the synaptic cleft. Which sequence of events is correct? A) 1 → 2 → 3 → 4 → 5 B) 2 → 3 → 5 → 4 → 1 C) 3 → 2 → 5 → 1 → 4 D) 4 → 3 → 1 → 2 → 5 E) 5 → 1 → 2 → 4 → 3. 66) Action potentials are normally carried in only one direction: from the axon hillock toward the axon terminals. If you experimentally depolarize the middle of the axon to threshold, using an electronic probe, then A) no action potential will be initiated.
B) an action potential will be initiated and proceed only in the normal direction toward the axon terminal. C) an action potential will be initiated and proceed only back toward the axon hillock.
D) two action potentials will be initiated, one going toward the axon terminal and one going back toward the hillock. E) an action potential will be initiated, but it will die out before it reaches the axon terminal.
67) Assume that excessive consumption of ethanol increases the influx of negative chloride ions into 'common sense' neurons whose action potentials are needed for you to act appropriately and not harm yourself or others. Thus, any resulting poor decisions associated with ethanol ingestion are likely due to A) increased membrane depolarization of 'common sense' neurons. B) decreased membrane depolarization of 'common sense' neurons. C) more action potentials in your 'common sense' neurons.
D) more EPSPs in your 'common sense' neurons. E) fewer IPSPs in your 'common sense' neurons.
