Step by step
Solved in 3 steps
- The question I have is how does change in the membrane potential trigger graded and action potentials for the transmission of signals? When the neurotransmitter molecules bind to ligand-gated ion channels on the receiving cell, does it cause depolarization of that cell?My question is how can spatial summation of synaptic potentials make it easier for a neuron to reach action potential threshold?My question is how can temporal summation of synaptic potentials make it easier for a neuron to reach action potential threshold?
- I am having trouble with the process with post synaptic membrane or what occurs during the time of post synaptic with the relationship of Acetylchlorine and Norepinephrine and epinephrine.What is a synapse? Explain the difference between an excitatory and an inhibitory synapse.Which serotonin agents is NOT acting via interaction with membrane serotonin receptors? a) Ondansetron b) Trazodone c) Sumatriptan d) Citalopram e) Ketanserin Please answer asap
- This is more of a neuroscience question but I wanted to ask: Why does a neuron that releases dopamine NOT release epinephrine?What are several ways in which drugs that are stimulates could increase the activity of the human nervous system by synapseParkinson's Disease Parkinson's disease is neurodegenerative 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. Explain how the signal transmission at a synapse in an individual with Parkinson's disease is different than an unaffected individual. Describe the normal process of signal transmission at a synapse. Start with the arrival of an action potential at the axon terminal and include the name of the neurotransmitter that is affected by Parkinson's disease. Explain how the process is different in individuals affected with Parkinson's disease.
- What is a synapse, and what role does it play in nerve transmission?I 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?Please let me know which one is correct and which one is incorrect and what might be the correct answer. This is about the autonomic nervous system
