Concept explainers

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.

Watch this short video (http://openstaxcollege.org/l/facialnerve) to see an examination of the facial nerve using some simple tests. The facial nerve controls the muscles of facial expression. Severe deficits will be obvious in watching someone use those muscles for normal control. One side of the face might not move like the other side. But directed tests, especially for contraction against resistance, require a formal testing of the muscles. The muscles of the upper and lower face need to be tested. The strength test in this video involves the patient squeezing her eyes shut and the examiner trying to pry her eyes open. Why does the examiner ask her to try a second time?

Cardiomyocytes contractile rate increases as Ca Icvels in cytosol risc. Releasing of Ca to the cytosol from endoplasmic reticulum is regulated by CAMP-dependant transporters in ER membrancs. Along with that, the CAMP concentration in cytosol is regulated by two signal moleeules- epinephrinc and acctylcholine. Epinephrine, binding to B,-receptors, clevates the concentration of CAMP in the cardiomyocytes and stimulates the cardiac output, and acetylcholine diminishes CAMP concentration and, therefore, depress myocardial contractility. Explain why, using the same signal transduction pathway, these two primary messengers cause the different eellular responses in the heart muscle. For that: a) draw the scheme of signal transduction for cpinephrine and acetyleholine; b) point out the differences in the pathways for these two primary messengers: e) explain the opposite biological effects of these signal molcecules.
