The table of neurotransmitters below is too simplistic. In reality, one neurotransmitter chemical has multiple actions in the nervous system. How is this possible?
An action potential has reached the axon terminal of a presynaptic cell. As a result of the action potential you would expect the movement of __________ into the presynaptic cell and the movement of __________ out of the presynaptic cell. Calcium : neurotransmitter Sodium : calcium Neurotransmitter : calcium Sodium : neurotransmitter
An undisclosed drug (Drug A) is a drug that can block voltage-gated K+ channels when being introduced into the bloodstream. Explain the effects of Drug A on the action potentials produced by a neuron. If Drug A could be applied selectively to a presynaptic neuron that releases an excitatory neurotransmitter, analyse how would it alter the synaptic effect of the neurotransmitter on the presynaptic cell. Remark: The word count limit (250 words only), no less than 100 words
Neurotransmitters are synthesized in____________ and are stored in _____________ .
Drugs called selective serotonin reuptake inhibitors (SSRIs) affect the reuptake of neurotransmitter by presynaptic cells. SSRIs are used for the treatment of depression. Serotonin normally causes an excitatory postsynaptic potential. Explain why neurotransmitter reuptake is important. And describe what effect the SSRI would have on the response of these postsynaptic cells and why.
Compare and contrast the events that occur at a neuromuscular junction (NMJ) and a neuron-neuron junction (a chemical synapse (CS)). Take it step by step, pointing out similarities or differences at each step. Begin with “Both processes begin with an action potential travelling down the axon.” and then tell me what is the same and what is different as the story unfolds.
A neurotransmitter called "GABA" decreases the rate of action potential generation in neurons, but the effect can be overridden by excitatory neurotransmitters. Alcohol binds to the GABA receptor and has the same effect. Alcohol must Select one: a. Cause depolarization in neurons b. Cause hyperpolarization in neurons c. Block calcium entry at the axon terminus d. Block voltage-gated sodium channels
Alcohol addiction is a condition in which a person experiencesdependent on alcohol and difficult to control its consumption. On the other hand, excessive alcohol consumption in the long term can cause disturbances in brain performance, including disturbances in memory, attention, coordination, and locomotion. How does alcohol affect the functioning of nerve cells and the central nervous system? What is the mechanism that occurs? Based on information from the literature, analyze what will happen to coordination and locomotion in someone who is addicted to alcohol and consumes large amounts of alcohol over a long period of time.
The image below shows a presynaptic cell releasing neurotransmitters that are being bound by the postsynaptic cell. EXPLAIN the physiological events that would occur in the postsynaptic cell after binding this neurotransmitter. Assume that the neurotransmitter is excitatory.
This is a biology question regarding nerve impulses. Neurofibromatosis type 1 is a condition where tumours can grow in the nerves near the skin. The growth of tumours prevents the action potentials from quickly travelling through the neurons. Identify the nerve structure from the image below and the division of the nervous system affected by neurofibromatosis type 1. CNS = Central Nervous System PNS = Peripheral Nervous System Select one: a. Nerve Structure Division of Nervous System 3 PNS b. Nerve Structure Division of Nervous System 4 CNS c. Nerve Structure Division of Nervous System 5 PNS d. Nerve Structure Division of Nervous System 1 CNS
Parkinson's Disease Parkinson's disease is a neurological degenerative disorder that affects movement. Most people affected with Parkinson's disease demonstrate rigidity, slow movement, and shaking. The symptoms of Parkinson's disease occur when the cells that produce dopamine neurotransmitters die in the brain. Since most symptoms of Parkinson's disease are caused by insufficient dopamine in the brain, many Parkinson's drugs either temporarily replenish dopamine or mimic the action of dopamine. Explain how the signal transmission at a synapse in an individual with Parkinson's disease is different than an unaffected individual. 1. List the steps involved in an action potential moving from the axon terminal of the pre-synaptic neuron to the dendrites of the post-synaptic neuron. 2. Explain how the process is different in individuals affected with Parkinson's disease.
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. Please include references.
