Paladinen [302]

Answer:

 The posterior crural is the type of region in human body which simply known as back of the leg part. It is basically used to denote in terms of laceration (CUT) in the given clinical report. So, it basically occur in back of the leg region in terms of layperson.  

Laceration is the type of wound which occur in the part of back of the leg according to the clinical report in question. It is basically contaminated by the bacteria.

Explain musclecontraction based on neuroelectrical factors, chemical interactions, and energy sources.
USPshnik [31]

Answer:

Neuroelectrical Factor

1. Potassium ions (K+) are greater inside the muscle cell than outside, whereas sodium ions (Na+) are greater outside than inside.

2. The inside of the cell is negatively charged electrically, whereas the outside is postively charged.

3. Nerve impulse reaching a neuromuscular junction causes axon endings to release the neurotransmitter acetylcholine

4. This makes the cell membrane permeable to Na+. They rush in creating an electrical potential. K+ begin to move out to try to restore the resting potential but cannot do so because so much Na+ rushes in.

5. This causes the muscle cell to generate its own impulse called the action potential, which penetrates deep into the muscle fiber via the T tubules

6. This action potential causes the sarcoplasmic reticulum to release Ca+ into the fluids surrounding the myofibrils

7. The Ca++ stops the action of the inhibitor substances troponin and tropomyosin (which kept actin and myosin apart), thus causing the contractile process to occur.

Chemical Factor

1. Ca++ combines loosely with myosin to form activated myosin

2. Activated myosin reacts with ATP, attached to the myosin, and releases energy from the ATP to form actomyosin

3. Myosin filaments have cross bridges that now connect with the actin and pull the actin filaments in among the myosin filaments

4. A sliding process occurs: the width of the A bands remain constant but Z lines move close. By now the sodium-potassium pump kicks in to restore the resting potential. Ca++ gets reabsorbed and contraction ceases

Energy Sources ATP

1. Glycolysis: glucose to pyruvic acid, net gain eight ATP if O2 present, if no O2 then lactic acid forms with net gain of two ATP.

2. Krebs citric acid cycle: pyruvic to CO2 + H2O + 30 ATP (28 ATP + 2 GTP)

3. Phosphocreatine in muscle cells: phosphocreatine --- creatine + PO4 ---ATP

4. Free fatty acids: fatty acids --- CO2 + H2O + ATP

A client who trains for triathlons has asked how much fluid he should consume between his morning runs and afternoon bike rides.
tiny-mole [99]

range of fluid intake would be most appropriate : 50-70%

What is average?

In everyday terms, an average is one number chosen to represent a list of numbers; it is often the sum of the numbers divided by the number of numbers in the list (the arithmetic mean). The average of the numbers 2, 3, 4, 7, and 9 (which add up to 25) is, for instance, 5. An average could be another statistic like the median or mode depending on the situation. Because the mean would be falsely high if it included the personal incomes of a few billionaires, the median—the amount below which 50% of personal incomes fall and above which 50% of personal incomes rise—is sometimes used instead.

All of the following will increase blood flow except
Damm [24]

Answer:

D. Decreasing vessel diameter

Explanation:

Cardiac output is the amount of blood pumped per unit time by heart. Increased cardiac output corresponds to increased blood pressure which will result in increased blood flow. In vasodilation the smooth muscles within the blood vessels relax making them wide hence decreasing vascular resistance leading to more blood flow. Decreased blood viscosity will also decrease the resistance to blood flow.

Decreasing vessel diameter will not increase the blood flow, it will rather restrict it because there will be more resistance to passage of blood due to small space.
