The nurse is explaining to a client with Parkinson disease the steps in which the neurotransmitter dopamine functions to impact motor movement. In which order will the nurse explain these steps?

Question

Standard Text: Click on the down arrow for each response in the right column and select the correct choice from the list.
Response 1. The substantia nigra produces dopamine.
Response 2. Dopamine travels to the corpus striatum.
Response 3. The dopamine is released.
Response 4. The dopamine finds receptors.
Response 5. The dopamine slows impulses down spinal neurons.
Response 6. Coordinated unconscious muscle movement occurs.

Answer 1

Correct Answer: 1,2,3,4,5,6
Rationale 1: The substantia nigra, a dark band of gray matter in the midbrain, is a primary producer of the neurotransmitter dopamine.
Rationale 2: The dopamine travels through axons along the nigrostriatal pathway to the corpus striatum.
Rationale 3: When dopamine reaches the nigrostriatal pathways, it is released.
Rationale 4: In the corpus striatum, dopamine encounters its receptors and produces multiple actions.
Rationale 5: Dopamine serves an inhibitory function, slowing the flow of impulses down spinal neurons.
Rationale 6: When dopamine is present, the normal flow of motor impulses from the corpus striatum helps to produce coordinated unconscious muscle movement.
Global Rationale: The substantia nigra, a dark band of gray matter in the midbrain, is a primary producer of the neurotransmitter dopamine. The dopamine travels through axons along the nigrostriatal pathway to the corpus striatum. When dopamine reaches the nigrostriatal pathways, it is released. In the corpus striatum, dopamine encounters its receptors and produces multiple actions. Dopamine serves an inhibitory function, slowing the flow of impulses down spinal neurons. When dopamine is present, the normal flow of motor impulses from the corpus striatum helps to produce coordinated unconscious muscle movement.
