Ch.11 - Subjecto.com In what way does the interior surface of a cell membrane of a resting (nonconducting) . An action potential works on an all-or-nothing basis. C) Specific sodium gates will open. B) are crucial in the production of neurotransmitters, C) are crucial for the development of neural connections. If the stimulus is more than the threshold value, then it will generate a nerve impulse that will travel across the entire length of the axon. buffering potassium and recapturing neurotransmitters are Polarization is the situation in which the membrane is electrically charged but non-conductive. The fastest conduction velocity occurs in the largest diameter nerve fibres. 4.) d) tracts, Which ion channel opens in response to a change in membrane potential and participates in the generation and conduction of action potentials? We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Two factors are essential for the release of the neurotransmitter from the presynaptic terminal: (1) depolarization of the terminal and (2) the presence of calcium ions (Ca2+) in the extracellular fluid. In this situation, sodium channels open and potassium channels are closed. Select the correct statement regarding synapses. a) the synaptic cleft prevents an impulse from being transmitted directly from one neuron to another Which of the following is not a special characteristic of neurons? This is called the absolute refractory period, and it is followed by a relative refractory period, during which another action potential can be generated, but only by a greater stimulus current than that originally needed. The polarization state is also known as the Unstimulated or non-conductive state. Name any four of them.. The rate of transmission and generation of nerve impulses depends upon the type of cell. c) neurolemma to another stimulus is the ________.A) depolarization, Strong stimuli cause the amplitude of action potentials generated to increase. a. insufficient stimulus. B) open ion channels to provoke rapid responses. zoneD) Secretory regionE) Trigger zone. A neuron that has as its primary function the job of connecting other neurons is called a(n) ________. Neurotransmitter inactivation is carried out by a combination of three processes. Select the correct statement about serial processing. negatively charged and contains less sodium.

a second nerve impulse cannot be generated until
