NROB60 Exam Questions With 100% Verified Answers Action Potential - answerDramatic redistribution of electrical charge across membrane. Rapid reversal of charge across membrane such that the interior becomes relatively positive (depolarization caused by influx of sodium) How to determine MP - answerMicroelectrode in cell, voltmetre used to measure electrical potential between tip of intracellular and extracellular microelectrode Membrane potential at rest - answer~-65mV Key parts of Acti...

NSC 3361 Exam 1 Questions and Answers All Correct Sequence of transmission at chemical synapse - Answer-1. Action potential travels down axon to axon terminal. 2. Voltage-gated calcium channels open and Ca2+ enters. 3. Synaptic vesicles fuse with membrane and release transmitter into the cleft. 4. Transmitter binds to post-synaptic receptor, causing EPSP or IPSP. 5. May bind to the presynaptic autoreceptors, decreasing release. 6. Neurotransmitter is inactivated by degradation or reuptak...

LIFSCI 7B XL - Animation: Reading Phylogenies Copy Questions and Answers Rated A+ What is the role of the axon hillock in neural signaling? The axon hillock integrates incoming signals and determines whether to initiate an action potential. How does myelination affect the speed of action potential propagation along an axon? Myelination increases the speed of action potential conduction by enabling saltatory conduction, where the signal jumps between nodes of Ranvier. Why do vo...

Logarithm - is the exponent of base 10 that equals the value of a number In decibel formulas how should values be logically arranged when comparing two numbers (V1 / V2) - If you expect a gain, place the higher number first. If you expect a loss, place the smaller number first. Explain negative decibel values - measurement just means "less than before," or in this case, "less than the reference level. It does not mean the basic unit it represents has a negative value Decibel - describes...
