The typical route of information from a nerve cell is via: The Soma The Axon The Dendrites The dendrite tree The Axon Hillcock
True/ False question on GABA-A receptors
GABA-A receptors are "inhibitory" because they are ligand-gated ion channels that allow chloride ions to move out of the cell. True or False
What is the electrical property of the cell membrane which explains the slower changes in potential (voltage) in response to a current change? Cytosolic Capacitence Cytosolic Resistance Channel Conductance Membrane resistance Membrane capacitence
Synaptic Vesicles are (Choose all that Apply) Are contained within the postsynaptic cell cytoplasm Fuse with the presynaptic membrane in response to increased intracellular calcium concentration House the neurtransmitters that will ultimately be released into the synaptic cleft in response to an action potential arr ...continues
Explain the fundamental differences between senstization , habituation, and classical conditioning?
A minature end plate potential (MEPP) is : Which of the following A quantal depolarization that occurs at the specialized region of a muscle fiber (end plate) at a neuromuscular junction. Is produced by the activation of post-synaptic receptors by the ligand acetylcholine (a neurotransmitter) Causes hyperpolarizati ...continues

A post synaptic ionotropic receptor permeant to only one ion is known to be inhibitory (Activation of the receptor generates an APSP) Chloride is able to pass through this ion channel. What would happen if this neuron was suddenly made permeable to Mg ions, would Mg ions flow into or out of the cell? Would the curr ...continues
The undershoot of the typical neuronal action potential ...
The undershoot of the typical neuronal action potential is due largely to increased permeability of the plasma membrane to potassium. True or False
Compare & contrast the molecular/biochemical events ... Sensitization
Compare & contrast the molecular/biochemical events associated with short-term sensitization and long-term sensitization in Aplysia. How is LTP (both early and late) of the mammalian hippocampus similar to and/or different from sensitizations in Aplysia?
