Answer:

pituilatry gland

Explanation:

The pituitary gland is sometimes called the "master" gland of the endocrine system because it controls the functions of many of the other endocrine glands. The pituitary gland is no larger than a pea, and is located at the base of the brain.

Why is there more creatine kinase in dmd muscles compared to average muscles

Nastasia [14]

Answer:

Explanation:

Almost everyone with a neuromuscular disorder has had, or will have, a creatine kinase test. But what exactly is creatine kinase (CK), and why are its levels measured in neuromuscular diseases?

CK, also known as phosphocreatine kinase, or CPK, is a type of protein called an enzyme. It catalyzes, or "encourages," a biochemical reaction to occur. The normal function of CK in our cells is to add a phosphate group to creatine, turning it into the high-energy molecule phosphocreatine. Phosphocreatine is burned as a quick source of energy by our cells.

However, the normal function of CK isn't as relevant, in this case, as what happens to CK when muscle is damaged. During the process of muscle degeneration, muscle cells break open and their contents find their way into the bloodstream. Because most of the CK in the body normally exists in muscle, a rise in the amount of CK in the blood indicates that muscle damage has occurred, or is occurring.

To measure CK levels, a blood sample is taken and separated into fractions that contain cells and a fraction that doesn't — the serum. The amount of CK in the serum is reported in units (U) of enzyme activity per liter (L) of serum. In a healthy adult, the serum CK level varies with a number of factors (gender, race and activity), but normal range is 22 to 198 U/L (units per liter).

Higher amounts of serum CK can indicate muscle damage due to chronic disease or acute muscle injury. For this reason, if you're scheduled to have blood drawn for a CK test to diagnose a potential muscle disorder, you should limit your exercise to normal activities before the test.

A 22-year-old man was in a motorcycle accident with resultant neck injuries that led to partial paralysis of the upper and lower

Arte-miy333 [17]

Answer:

We are given:

Minute Ventilation, MV = 6L/min

Respiratory Rate, RR = 30 b/min

PaO2 = 61mmHg

PaCO2 = 47mmHg

a) to find Tidal Volume, TV, we use:

TV = MV/RR

TV = 6/30

= 0.2litres => 200ml

For Alveolar ventilation, AV, we have:

AV = (Tidal Volume-dead space)×RR

AV = (200 - 150)×30

AV = 1500ml/min

The normal dead space value is 150ml.

Comparing both TV and AV with the normal values, it can be said that, since he has a TV of 200ml, he is defficient because a normal TV level is 500ml.

The man has an AV of 1500ml/min, which is low when compared to the normal AV value which is 4200ml/min.

2) The factor contributing to the deceased alveolar ventilation is the increase in PaCO2, in this case, the PaCO2 is 47mmHg, whereas the normal PaCO2 level is between 38-42mmHg

3) The muscle involved in this problem is the lower rib cage and thoracic cavity, while the nerve involved in this problem is the spinal cord.

4) The residual volume is decreased

5) Dyspenea simply means shortness of breath. It happens when a person experiences difficulty in breathing.

6) The cause of Dyspenea could be that the tidal Volume is lowered by the reduced diaphragmatic and intercoastal innervation or it could also be caused by chest trauma

7) The reflexes that causes tachypnea in this individual are the central and peripheral chemoreceptors. A individual has a PaO2 of 61mmHg and this low PaO2 causes the high breathing rate becauses peripheral chemoreceptors senses it and the medulla sends the signal out

Which sentence represents a hypothesis? environmental conditions affect the pollination of plants. boil 100 milliliters of water

schepotkina [342]

The best answer for this question would be:

environmental conditions affect the pollination of plants.

Because it depicts the starting information or theory that the researcher is stating. His theory is that the conditions of the plant will affect the plant, and therefore experiments on the procedure to prove his theory.<span> </span>
