1. T or F: Potassium ions are at high concentrations inside of cells, including
neurons: True
2. The action potential is a result of:: the movement of ions
3. The post-synaptic cell can be:: in glands, muscle cells and neurons
4. Th resting potential of a neuron is: -60mV
5. T or F: The cell body refers to the part of the neurons that begin at the
dendrites and extend to the axon terminal: false
6. T or F: Voltage gated ion channels open when a protein binds to the recep-
tor: false
7. T or F: Excitatory synapses cause hyperpolarization of post-synaptic cells: false
8. T or F: Acetylcholinesterase breaks acetylcholine into muscarinic acid: false
9. In the motor end plate, the event that is the immediate trigger for exocytosis
is: calcium ions
10. T or F: Fast Neurons as described in lecture require cytoplasmic signal trans-
duction to open an ion channel.: False
11. T or F: Only pre-synaptic neurons are coated with myelin.: False
12. T or F: When the presynaptic cell contacts a muscle cell, the synapse area is
called a motor end plate.: True
13. T or F: Receptors are made from membrane-bound polyribosomes.: True
14. The terminal web:: is a site of exocytosis
15. T or F: Excitatory synapses cause depolarization of the post-synaptic cell: True
16. T or F: The membrane potential (resting potential) is largely set by the Na-K-
ATPase pump.: true
17. The neural tissues are:: spinal cord, sensory neurons and brain
18. T or F: the axon from a pre-synaptic cell contacts the axon of another neu-
ron: false
19. T or F: The receptors in post-synaptic cells are the basis on which the synapse
can be defined as inhibitory or excitatory: false
20. 4 types of glial cells: schwann, oligodendrocytes, astrocytess and microglia
21. T or F: The axon hillock in the pre-synaptic neuron fires based on temporal
and spatial summation of inputs: true
