Describe the issue of tonicity for a solution. How does the level of tonicity impact the rate of movement, the direction of movement, and the combination of rate and direction of movement of materials across the membrane?
ANSWER: Tonicity is the indication of the concentration of the solutes within the solution that surrounds a cell or tissue of the body. This indication is used to assist with the determination of the hydrostatic pressures and osmotic drives involved with the movement of water across the membrane and the relative difference of the concentration of ions between the inside and outside of the membrane that is necessary for the indication of the membrane potential of the excitable tissues of the body. As it relates to the movement of solutions the direction and rate of movement is determined based on the indication that water will move from hypotonic regions to hypertonic regions while salts move in the opposite directions until all are in concentration balance (isotonic) across the membrane. Where Starling’s Law tells us that the greater the difference in concentration the larger the total movement of water will be; while Fick’s Law tells us that this greater difference will lead to faster movement too. Based on a hypotonic situation for the cell, water will flow into cell from the external environment leading the cell to swell until it undergoes cytolysis. While in a hypertonic situation for the cell, water will flow out of the cell into the external environment until the cell desiccates (dehydrates like when making jerky).
What impact does hydration have on the volume of the cells of the body and their ability to function appropriately?
ANSWER: Hydration impacts volume of the cells of the body by developing an isotonic, hypotonic, or hypertonic condition for the cell. Each of these conditions will impact the volume of the cell, the membrane potential of the cell and the overall functions of the cell. In an isotonic condition, the cell will have normal volume, normal membrane potential and be able to function normally. However, when dehydrated, the hypertonic condition leads to a reduced volume of the cell, an increased concentration of ions around the membrane that leads to a change in functions in the excitable tissues (neurons and muscles) that can lead to one cramping or having neurological issues (headaches and pour concentration and fatigue). Whereas if a hypotonic condition occurs, the cell will increase in volume and there can also be issues for excitable tissues, but instead of cramping and neurological issues associated with an ease of depolarization there will might be an inability to have enough ion movements to allow membrane potential change to cause cell’s to change their functions.
What are three principle types of cell junctions? For each describe the function for using that type of junction and then give an example of the tissue where the type of junction can be found.
ANSWER: The three principle forms of cell junctions are the tight, the gap and the desmotic junctions. The tight junctions form in tissues that allow for a barrier to be formed by the cells, the gap junctions form where there needs to be a delay in the action of one cell in the network from the joined cell, the desmotic junction forms in tissues where a network of cells must function as a coordinated massive cell. The tight junctions are typically seen in the epidermis of integument and are identified by cell membrane-to-cell membrane connection through transmembrane and exterior proteins of the two cells. The gap junction are the cell junctions typically seen between neurons and between a neuron and its target cell, these junctions are identified by cells being held a very short distance apart from each other by proteins known as connexons. The desmotic junctions are typically seen in cardiac muscle (the intercalated discs) and are identified by an interweaving of cytoskeletal and integral proteins between the two cells being joined by the desmosomes.
Differentiate between growth and differentiation of a cell within the body. What terms do we use to describe growth? What terms do we use to describe differentiation?
ANSWER: Growth is the process by which the cell or the body becomes larger through either an increase in mass in volume or in the total number of cells within the body. We typically discuss growth as the body gaining weight (mass) or becoming larger (taller or wider) than it had been in the past. At times we can mistake growth for maturation or differentiation of the cell or tissues of the body during the various growth (maturation) phases of development. On the other hand, differentiation is the process by which cells begin to function in a specialized manner based on the function that the cell has for the body. The end process of differentiation is the develop of the various types of cells that comprise the different tissues of the body that will allow for specialization of the cells into the subclassifications of the cell types within each of the various types of tissues of the body. Taken together growth and differentiation leads to the concept of maturation in which the embryo and fetus are able to take on the adult form during in utero development and then following birth allow the child to grow and develop into the juvenile and adolescent and eventually the mature adult.
