Draw a graph of the autonomic system and identify the neurotransmitters and receptors such as dopamine,norephinephrine and etc. and where it binds to alpha and beta. please explain as well.
Phenytoin (sodium channel blocker) and ethosuximide (calcium channel blocker) are anti-seizure drugs that stop seizures from happening. These drugs work by inhibiting electrical impulses (action potentials) from occurring. Explain the importance of sodium and calcium channels on a neuron and and the reasons why action potentials do not occur when these channels are inhibited. Be sure to include the phases of an action potential, the channels involved, and the importance of an action potential.

- We 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?arrow_forwardDefine the following terms:a. excitatory neurotransmitterb. inhibitory neurotransmitterc. retrograde neurotransmitterd. dopaminee. epinephrinearrow_forwardIn the overall scheme, of proposed causes of neurotransmitter dysfunction, the following is true: alteration of dopamine concentration influences obsession alteration of serotonin concentration can affect the attention function Dysfunctional production of the neurotransmitters, mentioned in class, can influence cognitive function dysfunction in the production of neurotransmitters happens only in the elderlyarrow_forward
- Identify two neural pathways in the brain that use dopamine as a neurotransmitter, andexplain their significance.arrow_forwardDescribe the neurotransmitters. Give examples of how they might occur in the body.arrow_forwardReserpine is a drug that can control high blood pressure by reducing the number of catecholamine neurotransmitters present in the synapse. Epinephrine, norepinephrine, and dopamine are examples of catecholamine neurotransmitters. One of the known side effects of reserpine is to cause the symptoms of Parkinson’s disease. Parkinson's disease is associated with dopamine. Parkinson's disease occurs when the nerve cells in the part of the brain that controls muscle movement are gradually destroyed and the neurons can no longer produce dopamine to coordinate muscle movements. Reserpine causes symptoms by a. inhibiting the release of dopamine from the presynaptic neuron b. blocking the dopamine receptor in the postsynaptic neuron c. breaking down the neurotransmitter acetylcholine in the synapse d. breaking down cholinesterase enzyme in the synapsearrow_forward
- Identify two neural pathways in the brain that use dopamine as a neurotransmitter, and explain their significance.arrow_forwardNervous system functions that directly employ acetylcholine neurotransmitters are referred to as cholinergic. Drugs that might be therapeutic in treating the symptoms of dopamine loss in Parkinson’s disease could include multiple choice 1 dopaminergic agonists and cholinergic antagonists. dopaminergic antagonists and cholinergic antagonists. dopaminergic antagonists and cholinergic agonists. dopaminergic agonists and cholinergic agonists. 2. From the information provided, drugs used to treat Parkinson’s disease symptoms will act at which location? multiple choice 2 The globus pallidus The substantia nigra The striatum 3.
