Explanation:

Action potential travels down the axon in response to nerve stimulus.
Action potential travels down the T Tubule and into Sarcoplasmic Reticulum (SR)
Action potential causes Ca2+ release from SR
Ca2+ binds to troponin. Troponin moves tropomyosin uncovering myosin binding site on actin
Myosin binds to actin
Myosin pulls actin chain along and Sarcomere shortens leading to contraction!
Ca2+ pumps restore Ca2+ to SR  relaxation!

At synaptic junctions:

The action potential travels along the membrane until the synapse where it’s electrical depolarization leads to the opening of channels allowing only sodium ions to enter
these flow through a presynaptic membrane until the concentration is built up, activating ion sensitive proteins attached to vesicles containing neurotransmitters like acetylcholine
this leads to changes in the proteins leading to the fusion with the membrane of the presynaptic cell, so vesicles are open and neurotransmitter is released. The neurotransmitter diffuses across to chemical receptors on the presynaptic cell where they bind temporarily. This increases the permeability of the sarcolema to Na+;a new action potential is generated
This action potential in the muscle, travels along T-tubules, and Ca+ ions are released by the sarcoplasmic reticulum into the sarcoplasm

Ca and troponin combine, pulling myosin filaments, exposing the actin filament's myosin binding sites
cross-bridge formation occurs, leading to the sliding of filaments. ACH degraded in the synapse. Na ions are not released, and the action potential is not transmitted.
the Ca channels on the SR close, while Ca is reabsorbed stopping Ca-troponin binding, closing myosin binding sites on actin and leading to cross bridge separation. The muscle fiber relaxes in their resting states.

For each kilogram of a person's weight, 2.5 milligrams of a drug is to be given. what dosage should be given to a child who wei

Free_Kalibri [48]

So, basically the question is asking what is the dose of a medication that is 2.5mg/kg.

Assuming that the child does NOT weigh 7171lbs but 71lbs; which would equal around 32kg (71 x 0.45).

So this child would have 2.5mg per 32kg. 32kg x 2.5= 80mg of medication.

One formal group is a committee looking into how the health care reform would affect the company.

<h3>A formal group is what?</h3>

A formal group is one that has been formed to carry out beneficial work for the company. A division, department, work group, or committee are examples of formal groups. It might be either permanent or passing.

<h3>What financial effects will the new health care reform law have?</h3>

A number of payment and delivery system modifications will be made as a result of the health reform legislation introduced in March 2010 in an effort to significantly slow the development of health care costs. Most analyses of the new reform bill have primarily considered its effects on the government budget.

<h3>How have the most recent health care reforms altered business procedures?</h3>

Recent health care reforms have significantly altered market processes by enhancing market approval restrictions, enhancing post-market surveillance, and utilizing comparative effectiveness research.

With the intention of "improving the quality and affordability of health insurance, lowering the uninsured rate by expanding public and private," the health care reform was put into effect.
