Question

initial 16) In image shown to right, what type(s) of neural signal would you expect transduction site to see at the indicated location? (2 points) c) a) axon terminal 17) In a typical neuron, where would you expect to observe a graded potential? Choose ALL that apply. (2 points) a) dendrite b) presvnaptic terminal gger zone 18) In a typical neuron, where would you expect to find Hodgkin-Huxley voltage-gated Na channels (based on the typical function of these channels)? Choose ALL that apply. (2 points) a) dendrite b) presynaptic terminal c) trigger zone 19) What is the correct sequence of events in a stretch-sensitive sensory neuron? (4.5 points) * action potential(s) * action potential propagation graded potential (receptor potential) neurotransmitter release e opcning of mcchanically-gated ion channcls * opening of voltage-gated calcium channels . opening of voltage-gated sodium channels * sensory stimulus (muscle stretch) * summation of graded potentials 20) What is the correct sequence of signal transduction? (There can be missing steps, but the sequence must be correct.) (2 points) a) sensory stimulus -> graded potential in afferent -> action potential(s) in afferent -> neurotransmitter release by afferent b) neurotransmitter release by afferent -> action potential(s) in efferent -> neurotransmitter release by efferent -> graded potential in muscle-> muscle contraction c) graded potential in efferent-> action potential(s) in efferent ->neurotransmitter release by efferent -> muscle contraction d) All of the above are correct e) None of the above are correct
