Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.

Epilepsy is a condition which results in seizures stemming from excessive or abnormal activity of neurons. This can occur either from hyperexcitability of excitatory neurons, or impairment of inhibitory neurons. That is to say, either the excitatory pathways become overactive, or the inhibitory pathways, designed to temper the excitatory pathways, are not active enough. Much of the research done on epilepsy focuses on voltage-gated sodium channels, and to date over 700 different mutations to the channel have been identified as playing a role in epilepsy. The means by which these mutations contribute to epilepsy is quite complex, but for the sake of this CAL, let's simplify and apply what we have learned so far to identify potential mechanisms for this condition. In what way could voltage-gated sodium channels be affected in excitatory neurons which would increase the likelihood of the neuron firing an action potential? (one correct answer) The inactivation gate is slower to close. The…
