John Hughes and Hans Kosterlitz identified the endorphin receptor in frogs, and concluded that animals have a "built in" opioid system. To make sure that endorphins are truly neurochemicals, which of the following question should we ask these gentlemen? Please select all that apply.a) Are endorphins released in response to presynaptic depolarization?
b) Do endorphins interact with postsynaptic receptors?
c) Are endorphins found in presynaptic cells?
d) Are endorphins subject to reuptake?
Given what you already know about the sensation of pain, what is the expected change in membrane potential when pain is felt by sensory receptors?
Select one:
a. The nerve impulses increase in strength and lower the threshold potential.
b. The nerve impulses occur more frequently, thereby transmitting more action potentials according to the intensity of pain.
c. The nerve impulses occur more frequently and prevent neurons from entering the refractory period.
d. The nerve impulses increase in strength, thereby making the maximum membrane potential higher than normal.
The release of a neurotransmitter from a terminal button produces an inhibitory postsynaptic potential (IPSP) in the postsynaptic neuron. What is the most likely mechanism by which this occurs?
A.
the neurotransmitter opens chemically activated chloride channels
B.
the neurotransmitter activates a second messenger which then opens calcium channels
C.
the neurotransmitter is glutamate
D.
the neurotransmitter acts on a G-protein linked receptor which opens sodium channels

- The difference between the channels along the axon and the channels in the axon terminal is that? a) axon channels are voltage-gated sodium channels and axon terminal channels are voltage-gated calcium channels b) there is no difference c) axon channels are voltage-gated sodium channels and axon terminal channels are ligand- gated sodium channelsarrow_forwardCocaine affects a synapse by blocking the reuptake or reabsorbtion of the neurotransmitter dopamine by the presynaptic neurons. Therefore,the levels of dopamine continue to build in the synapse, causing certain effects on the body. A.

- Because the long axons of neurons look like electrical wires, and both neurons and electrical wires conduct electricity, it is tempting to equate the two. Compare and contrast the functioning of axons and electrical wires in terms of their structure and the nature of the electrical signals they conduct.
