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

According to the AHDI the virgule is used to indicate the word____ in laboratory values and other equation or the word ___ in bl
vredina [299]

According to the HDI the comma is used to indicate the word "decimal place" in laboratory values and another equation or the word "by" in blood pressure (BP) and visual acuity readings.

<h3>What is the HDI and what does it assess?</h3>

The HDI is an average measure of basic human development achievements in a country. Like all averages, the HDI masks the inequality in the distribution of human development among the population at the country level.

With this information, we can conclude that according to the HDI the comma is used to indicate the word "decimal place" in laboratory values and another equation or the word "by" in blood pressure (BP) and visual acuity readings.

what condition is most likely represented by clear fluid draining from the nose of a client that suffered a trauma to the head s
lubasha [3.4K]

When you have a runny nose, "brain fluid leaking" typically isn't the first thing that comes to mind.

<h3>Why does CSF flow out of my nose?</h3>

The skull bone injury causes CSF to seep through the nose. Drainage of clear, watery fluid through one or both sides of the nose is the most typical sign of a CSF leak. When bending forward, tilting the head, or straining, this leaking can get worse.

<h3>Why is clear fluid dripping from my nose?</h3>

Allergies and illnesses like the common cold and influenza are the most frequent causes of clear liquid pouring from the nose. Another cause of a persistent runny nose is vasomotor rhinitis, in which there is no obvious reason why the condition exists. A leaking nose can be caused by nasal polyps, migraines, foreign bodies, and, very rarely, certain tumors.

Oogonia multiply until the fifth month. within six months after birth, each will transform into a:_____.
kvv77 [185]

Oogonia multiply until the fifth month .within six months after birth ,each will transform into a primary oocyte .

What is oogonia ?

During foetal stag of development the embryo develops the germinal epithelium of ovary .some of the cells of  germinal epithelium enlarge and divide mitotically . the dividing cells projects into the stroma as a cord known as the egg tube of Pflugar;which later becomes a round mass ,called the egg nest .all these dividing cells are  egg mother cells known as Oogonia.this is derived from the endodermal lining of the embryonic yolk sac which comes to lie in the ovary of the female ( while it is still an  embryo ).

What is primary oocyte?

One cell of the egg nest grows but does not divide furter so as to form the primary oocyte.the primary oocyte is diploid and enters the growth phase.it is dormant stage ,nucleus intact ,female is born with these in her ovary.every month primary oocytes resume oogenesis and start developing growth and development in the onset of puberty.

Hence the correct answer is Primary oocyte.
