Step by step
Solved in 2 steps
- Assume presynaptic excitatory neuron A terminates on a postsynaptic cell near the axon hillock and presynaptic excitatory neuron B terminates on the same postsynaptic cell on a dendrite located on the side of the cell body opposite the axon hillock. Explain why rapid firing of presynaptic neuron A could bring the postsynaptic neuron to threshold through temporal summation, thus initiating an action potential, whereas firing of presynaptic neuron B at the same frequency and the same magnitude of EPSPs may not bring the postsynaptic neuron to threshold.From an action potential traveling towards the presynaptic terminal to the potential change in the post synaptic cell, write out each step of ionotropic synaptic transmission. pick a specific neurotransmitter and characterize the appropriate postsynaptic outcome.Name three ways to stop the effect of a neurotransmitteron the postsynaptic membrane. Give an example of each.
- which way does the neurotransmitter NO moveOrganize the following steps into the correct signal transmission across a synapse. 1. Neurotransmitter molecules diffuse across the synaptic cleft 2. Neurotransmitter molecules bind to postsynaptic neurotransmitter receptors 3. Synaptic vesicles release neurotransmitter molecules 4. Impulse reaches the synaptic knob of the presynaptic neuronTwo excitatory synapses on a neuron fire at the same time as one inhibitory neuron. Each synapse comes from a different presynaptic neuron. Explain what happens at each synapse (in the post-synaptic neuron) and what determines whether this neuron will fire.
- The correlation between neurons can explain the basis of the synaptic modification, that is, how much they can connect to each other or if they are not synchronized, how much they can lose or weaken their connections. Draw a picture of an excitatory synapse such as glutamatergic with its receptors between the pre- and postsynaptic neuron.Spastic paralysis (resulting from the failure of muscles to relax), induced by the neurotoxin strychnine, occurs when this poison blocks the binding of: the excitatory neurotransmitter acetylcholine to post-synaptic sodium channels the excitatory neurotransmitter glutamate to post-synaptic calcium channels the excitatory neurotransmitter serotonin to post-synaptic potassium channels the inhibitory neurotransmitter glycine to post-synaptic chloride channels the inhibitory neurotransmitter melatonin to post-synaptic bicarbonate channelsSynaptic terminal Neurotransmitter SENDING NEURON Vesicle Calcium channel Receptor for neurotransmitter RECEIVING NEURON Synaptic cleft
- 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 wordsSelect the best answer or answers from the choices given: Inhibition of acetylcholinesterase by poisoning blocks neurotransmission at the neuromuscular junction because (a) ACh is no longer released by the presynaptic terminal, (b) ACh synthesis in the presynaptic terminal is blocked, (c) ACh is not degraded, hence prolonged depolarization is enforced onthe postsynaptic cell, (d) ACh is blocked from attaching to the postsynaptic ACh receptors.Which of the following are the likely explanations for the failure of a postsynaptic neuron to trigger an action potential? Select all that apply. The EPSPs are neutralized by the neurotransmitter The summation of IPSPs and EPSPs is insufficient to depolarize the cell to threshold The synapses generating the EPSPs are too close to the axon hillock The synapses generating the EPSPs are too far from the axon hillock
