Question

What would be the answer of #15, I am between c and d the various velocities at which axons conduct action potentials? a. Myelination d. Diameter e None of these; all are fikely factors 11. Neurons that relay sensory signals toIntegrative centers a. interneurons b. synaptic neurons. c. efferent neurons afferent neurons. e.motor neurons 12. A decrease in the absolute value of the membrane potential toward zero is cal epolarization b. an action potential. c hyperpolarization. d. a membrane potential. e.voltage. 13. The transmission of a signal at the vertebrate skeletal neuromuscular junction consists of the following steps: 1. Chemically regulated ion channels on the postsynaptic membrane are activated calcium ions enterthe presynaptic cell 3. An action potential depolarizes the presynaptic membrane 4. Acetylcholine is released from the presynaptic neuron by exocytosis 5. Acetylcholine binds to receptors on the postsynaptic membrane. What is the correct sequence of these events? a. 4-2-1-5-3 b. 2-4-1-3-5 c. 1-2-3-4-5 2-4-5-1 e 2-5-4-1-3 14. Escape from a predator might require nearly instantaneous, reflexive neuronal reaction. Such a response is most likely to be mediated by a. metabotropie synapses d. ionotropic synapses CE?electrical synapses c. mEPSPs e. none of these 15. Two sets of axons carry stimuli near the axon hillock One set produces an IPSP and the other set produces an EPSP. If both a. There will be a hyperpolarization. b. An action potential will be produced sets produce action potentials at the same time, what is the likely effect at the axon hillock? The potentials created will cancel each other out There will be a depolarization but no action potential e. None of these 16. In the figure on the right, A, B, C, D, and E represent incoming synaptic inputs on a postsynaptic cell. At what point in the figure is depolarizing temporal summation occurring? b. 2 e. 17. Which of the following regarding the mechanism of vesicular docking and release is false? a. Targeted vesicles move to active zones where they attach reversibly b. Docking is mediated by the formation of a SNARE complex. c. The v-SNAREs and t SNARES interact to hold the vesicle at the release site d. Fusion is triggered by the binding of Ca to synaptotagmin. All of the above are true; none is false.

Explanation / Answer

Answer is D that is there will be a depolarization but no action potential .nthis is due to the direction of the potential in both the direction although there will be an effect on the membrane that is it's depolarization
