35.2 How Neurons Communicate: Which of the following is true?
A. Considering a pair of communicating neurons, the neuron receiving the signal is called the presynaptic neuron
B. There are three types of synapses: chemical, electrical, and magnetic
C. Synaptic vesicles contain neurotransmitters; these vesicles can fuse with the presynaptic membrane and release their contents into the synaptic cleft
D. Release of calcium in dendrites causes dendrites to release neurotransmitters into the axonal cleft
E. Neurotransmitters always have excitatory effects on the post-synaptic membrane
35.2 How Neurons Communicate: If a resting neuron were to suddenly open sodium channels in its cell membrane, which of the following would be an expected outcome?
A. Both sodium and potassium cations would enter the cell through the sodium channels
B. The cell's membrane potential would move from around -70 mV to become closer to zero or become positive
C. Sodium would rapidly leave the neuron through the open sodium channels
D. neurotransmitters could enter though the sodium channels
E. sudden opening of sodium channels would cause increased pressure inside the cell, possibly causing the cell to burst
35.2 How Neurons Communicate: What is illustrated by this diagram?
A. inhibitory post-synaptic potentials (IPSP's)
B. excitatory post-synaptic potentials (EPSP's)
C. a threshold potential
D. synaptic plasticity
E. Lou Gehrig's Disease
