5 True/False questions
Neurotransmitter (NT) → Gap in the myelin sheath of certain axons where an action potential may be generated. In saltatory conduction, an action potential is regenerated at each node, appearing to "jump" along the axon from node to node
Synapse → The junction where a neuron communicates with another neuron or other cell across a narrow gap via a neurotransmitter(chemical) or an electrical coupling.
Actin → ...
Temporal Summation → A phenomenon of neural integration in which the membrane potential of the post-synaptic cell in a chemical synapse is determined by the combined effect of EPSPs or IPSPs produced in rapid succesion
Hyperpolarization → A change in a cell's membrane potential such that the inside of the membrane becomes more negative relative to the outside. Hyperpolarization reduces the chance that a neuron will transmit a nerve impulse.
