Presentation Transcript

  1. Transmission of Dopamine 1. The receptor responsible for the uptake of dopamine molecules is a … a. target cell b. dopamine transporter (DAT) c. synaptic cleft This is not the correct answer. Please review the ERM entry “Transmission of Dopamine” and try again.

  2. Transmission of Dopamine 2. Dopamine transport (DAT) molecules are unusual in that they are found… a. Outside of the synaptic cleft b. Inside the nucleus c. Inside of vesicle This is not the correct answer. Please review the ERM entry “Transmission of Dopamine” and try again.

  3. Transmission of Dopamine • 3. Dopamine is packaged in _____________ inside of the dopaminergic neuron.… • a. Vesicles • b. Nuclei • c. Synaptic clefts This is not the correct answer. Please review the ERM entry “Transmission of Dopamine” and try again.

  4. Transmission of Dopamine • 4. A (n)____________ causes the neuron to release dopamine. • a. Accident • b. Movement • c. Action potential This is not the correct answer. Please review the ERM entry “Transmission of Dopamine” and try again.

  5. Transmission of Dopamine • 5. The concept that one dopamine neuron can impact several target cells is called … • a. Dopaminergictone • b. Volume transmission • c. DAT This is not the correct answer. Please review the ERM entry “Transmission of Dopamine” and try again.

  6. Transmission of Dopamine • 6. When a dopamine molecule is released, it will ____________ until taken up by DAT or a target cell receptor. • a. Diffuse • b. Exocytosis • c. Stabilize This is not the correct answer. Please review the ERM entry “Transmission of Dopamine” and try again.

  7. Transmission of Dopamine • 7. When a dopamine molecule attaches to a target cell receptor, it ____________ the functioning of that neuron. • a. Activates • b. Eliminates • c. Modifies This is not the correct answer. Please review the ERM entry “Transmission of Dopamine” and try again.

  8. Transmission of Dopamine • 8. Volume transmission keeps a constant concentration of dopaminergic molecules in the striatum. This is known as … • a Volume transmission • b. Dopaminergictone • c. Resting potential This is not the correct answer. Please review the ERM entry “Transmission of Dopamine” and try again.
