## Educational Content: Neural and Immune Responses ### Multiple Choice Questions: **54. A neuron can relay a more intense signal by:** - (a) sending a stronger action potential - (b) sending more action potentials in a given amount of time - (c) sending an action potential that travels more quickly - (d) sending out a longer action potential Correct Answer: **(b) sending more action potentials in a given amount of time** **55. The reasons that wasp spray acts so quickly include that it:** - (a) disrupts the action potential of motor neurons - (b) stops the secretion of acetylcholine into the synaptic cleft - (c) inhibits the action of cholinesterase in the synaptic cleft - (d) alters the unique action of insect cell muscles ### Matching: Pair off the term and its best definition/example. - **56. B-cells** - (c) includes the brain and spinal cord - **57. osmoregulation** - (e) birds and mammals are - **58. Cholinesterase** - (a) skin, phagocytes invade bacteria. ### Explanations for Questions: **52. What causes an action potential to be generated?** - (a) the sodium-potassium pump - (b) ion channels are opened and positive ions diffuse out of the cell - (c) ion channels are opened and negative ions diffuse out of the cell - (d) ion channels are opened and positive ions diffuse into the cell **53. The movement of an action potential along a neuron is most like:** - (a) the ripples created by dropping a pebble into a pond - (b) a solid tower emitting a signal that reaches only a very small region - (c) a crowd at a sporting event that spreads out gradually - (d) the sound of your voice spreading out as you yell loudly to your friend while at the park Answer: **(a) the ripples created by dropping a pebble into a pond** ### Explaining Graphs and Diagrams: This document does not contain any graphs or diagrams. The relevant content is provided as multiple-choice questions, matching terms with definitions, and factual explanations for how neural and immune systems operate.
