Solved in 4 steps
- Myasthenia gravis is a disease that leads to a marked decrease in the number of acetylcholine (Ach) receptors at the neuromuscular junction. As a result, suppose only about 200 (instead of 2000) Ach receptor-channels are opened by each quantum of Ach. The Ach-gated channels that survive operate normally and each cause a depolarization of about 0.25 x 10-3 mV when open. The function of the presynaptic terminal is normal and an action potential will cause the release of 100 quanta of neurotransmitter. Part a.) For a patient with myasthenia gravis, what would be the size (in mV) of a miniature excitatory post-synaptic potential (or that associated with one quantum of Ach)? a.) 0.05 mv b.) 0.25x10-4 mv c.) 0.25x10-3 mv d.) 0.5x10-3 mv e.) 0.5 mv Part b.) For a patient with myasthenia gravis, what would be the size (in mV) of the full excitatory post synaptic potential consequent to the entry of an action potential into the presynaptic terminal of the neuromuscular junction? a.) 70 mv…Required information Multiple Choice Local currents Action potential Acetylcholine is released into the synaptic cleft under the influence of Sodium ions 0:00 0:45 Low concentration of choline Calcium ions -Presynaptic terminal 1x OThe following concentrations of Na+ and K+ ions: [Na+]o = 120 mM, [Na+]i = 6 mM,[K+]o = 2 mM, and [K+]i = 150 mM.

Is this under physiological control?Several conserved arginine residues in the voltage-sensor domain allow voltage-gated potassium channels to sense and respond to membrane depolarization. True FalseAction potentials propagate in one direction because of: O K+ Voltage-gated Channels become inactive for a while O Nat Voltage-gated Channels become inactive for a while O K+ nongated Channels become inactive for a while O Nat nongated Channels become inactive for a while
- Following the arrival of an action potential in stimulated cells, synaptic vesicles rapidly fuse with the presynaptic membrane. This happens in less than l ms. What mechanisms allow this process to take place at such great speed?Activation of which pathway leads to a disinhibition of the thalamus and increased cortical activation?
