- Sympathetic innervation can have pro- and anti- inflammatory effects. Which of the following statements does not support this suggestion relative to a mouse model of inflammatory bowel disease (IBD). O Mice lacking the beta2-adrenergic receptor were less susceptible to this experimental IBD Catecholamines acting on alpha2-adrenoreceptors led to proinflammatory (IL-1beta, IL-6, and TNF-alpha) production worsening the IBD in mice Mice lacking the beta2-adrenergic receptor were more susceptible to this experimental IBDWhat is the benefit of having different types of adrenergic receptors in the body? What is e.g. specific to beta-2 receptors?Epinephrine binds to a set of adrenergic receptors found on a variety of cell types. Which of the following would NOT be an expected outcome of this binding?
- The following diagram represents a typical serotonergic synapse. Where, specifically, do antidepressants work (e.g. SSRI)? Neurotransmitter Neurotransmitter transporter Аxon Synaptic vesicle terminal Voltage- gated Ca?+ channel Synaptic cleft Receptor Postsynaptic density Dendrite Neurotransmitter Synaptic Vesicle Neurotransmitter transporter (aka Reuptake transporter) Receptor O All of the aboveI am confused about the process of rod cells in the dark. In the dark, rod cells are unstimulated and therefore the sodium is able to enter and depolarize the cell, stimulating the release of glutamate to the bipolar cell. However, this increase in glutamate in the bipolar cell inhibits the release of action potential from the bipolar cell to the ganglion cell. This doesn't make sense to me because shouldn't there be an increase in action potential since the rod cells are supposed to function in the dark?In cholinergic neurotransmission, inhibition of the choline transporter will affect the normal synthesis and release acetylcholineTRUE OR FALSE

- Our body expends a lot of energy activating and propagating the mass activation response of the sympathetic nervous system. Why is it necessary for us to have such an “expensive” mechanism at our disposal?A ________ potentail is a local, graded depolarization in a receptor cell triggered by the threshold stmulus opening the ion channels generator graded action positiveWe talked about drug effects on neurons in sequence. The effect of alcohol is multi-faceted and the following question asks you to apply your knowledge. Imagine two neurons in sequence. The presynaptic neuron is GABAnergic and the postsynaptic neuron is dopaminergic. The effects of alcohol are not fully understood but it does seem to inhibit GABAnergic neurons. How would the release of dopamine from the postsynaptic neuron change in this case? Explain your answer, being sure to make each connection between concepts clear. If alcohol instead inhibited dopaminernergic neurons, in what way might the ion flow change in the dendrites of the postsynaptic neuron of this example?
