Answer:
The correct answer will be:
1. Acetylcholine binds to receptors on the motor end plate
2. Chemically-regulated ion channels open, causing depolarization
3 End plate potentials trigger action potential(s).
4. Transverse tubules convey potentials into the interior of the cell
5. Ca++ is released from the sarcoplasmic reticulum
6. Ca++ binds to troponin, pulling on tropomyosin
7. Binding sites on actin are uncovered, allowing myosin to bind and carry out power strokes
8. Force increases.
9. Ca++ is pumped (re-sequestered) into the sarcoplasmic reticulum
10. Force decreases.
Explanation:
The muscle contraction is a highly controlled mechanism which begins at the neuromuscular junction with the release of the acetylcholine neurotransmitter. This neurotransmitter causes the depolarization of the membrane by binding to the receptors of the motor end plate which generates an action potential. This action potential is transmitted via T-tubules from sarcolemma to the sarcoplasmic reticulum.
The sarcoplasmic reticulum releases calcium ions which binds to the troponin protein. This troponin removes the protein tropomyosin from the actin causing the rotation of the tropomyosin exposing the binding sites for myosin. The myosin binds to the actin using energy from the ATP which pulls the actin causing contraction. Another ATP binds the myosin head which weakens the bond between myosin and actin which releases the myosin which decreases the force between them decreases and the muscles relax.
Answer:
The blood pressure is directly proportional to the total length of the vessel.
Explanation:
The blood pressure is directly proportional to the total length of the vessel.
The long blood vessel will have higher the resistance and the flow of blood will be lower.
Thus, making intuitive sense, as with blood volume, as the vessel's enhanced surface area will impede blood flow. This lowering area will lead to the higher blood pressure through the blood vessel. Similarly with the reduction in the resistance of the blood vessel, the blood flow will boost.
Medicare is a US government health insurance that is part of the Social Security Administration and covers the:
- medications, etc of eligible people under the plan.
<h3>What is Medicare Advantage Plan?</h3>
This refers to the medical plans that are covered by Medicare-approved private companies that adhere to the rules set by Medicare and are sometimes known as “Part C” or “MA Plans,”.
The persons that are eligible for medicare in the United States are senior citizens.
These are people between the ages of 65 and older and need to sign up for Medicare 3 months before they turn 65 and may get it quicker if they have disabilities.
Hence, we can see that your question is incomplete so a general overview of medicare health plans and their eligibility was given so you would have a better understanding of the concept,
