Arrange The Structures Below In The Order In Which Signals Travel Through Them?

The structures below play an important role in the transmission of signals between cells in the body. In order to understand how these signals are transmitted, it is necessary to understand the order in which they travel through these structures.The first structure in the signal pathway is the cell membrane. This is a thin, selective barrier that surrounds all cells and controls the flow of materials in and out of the cell. The cell membrane is important for the transmission of signals because it is responsible for receiving signals from the outside of the cell and transmitting them to the inside.The next structure in the pathway is the cytoplasm. This is the jelly-like material that fills the interior of the cell and contains the cell’s organelles. The cytoplasm is important for signal transmission because it contains the proteins and other molecules that are necessary for signal transduction.The final structure in the pathway is the nucleus. This is the control center of the cell and contains the cell’s DNA. The nucleus is important for signal transmission because it is responsible for translating the signals that are received by the cell into instructions that the cell can use to carry out its functions.

What are the 7 steps of muscle contraction?

  • Muscle contraction occurs when the filaments within the muscle fibers slide past one another, generating force.
  • The process of muscle contraction is initiated by nerve impulses that are transmitted to the muscle cells.
  • The following are the seven steps of muscle contraction:1.
  • Nerve impulses are transmitted to the muscle cells.
  • 2.
  • The muscle cells are stimulated, causing the filaments to start sliding past one another.
  • 3.
  • The filaments continue to slide until they are completely overlapped.
  • 4.
  • The muscle cells produce more force, causing the filaments to slide even further.
  • 5.
  • The muscle cells reach their maximum force output and the filaments are completely overlapped.
  • 6.
  • The filaments start to slide back to their original position.
  • 7.
  • The muscle cells relax and the process is complete.

What are the 8 steps of muscle contraction?

There are eight steps involved in muscle contraction: (1) activation of the motor neuron, (2) release of calcium from sarcoplasmic reticulum, (3) binding of calcium to troponin, (4) cross-bridge formation between actin and myosin, (5) sliding of actin and myosin filaments, (6) muscle shortening, (7) termination of the action potential in the motor neuron, and (8) reuptake of calcium into sarcoplasmic reticulum.Each of these steps is essential for muscle contraction to occur. (1) The motor neuron must be activated in order for the signal to reach the muscle. (2) Calcium must be released from the sarcoplasmic reticulum in order to bind to troponin and initiate cross-bridge formation. (3) Cross-bridge formation is necessary for the sliding of actin and myosin filaments, which is what causes muscle shortening. (4) The action potential must be terminated in the motor neuron in order for muscle contraction to cease. (5) Finally, calcium must be reuptaken into the sarcoplasmic reticulum in order to prepare for the next muscle contraction.

What are the 5 steps of muscle contraction?

There are five steps involved in muscle contraction: (1) activation of the motor neuron, (2) release of calcium from the sarcoplasmic reticulum, (3) binding of calcium to troponin, (4) cross-bridge formation, and (5) muscle contraction.The first step, activation of the motor neuron, occurs when the motor neuron is stimulated and sends a signal to the muscle cell. The second step, release of calcium from the sarcoplasmic reticulum, occurs when the signal from the motor neuron triggers the release of calcium from the sarcoplasmic reticulum. The third step, binding of calcium to troponin, occurs when calcium binds to troponin, which is a protein located on the thin filament. The fourth step, cross-bridge formation, occurs when the calcium-bound troponin changes the conformation of the myosin head, which then can bind to actin. The fifth and final step, muscle contraction, occurs when the cross-bridges between the myosin heads and actin filaments are formed and the myosin heads undergo a power stroke, which results in the shortening of the muscle.

Which of the following is the correct order of events to signal a muscle to contract?

There are four main events that must take place in order for a muscle to contract: (1) the release of Ca2+ from the sarcoplasmic reticulum, (2) the binding of Ca2+ to troponin, (3) the cross-bridge cycling between myosin and actin, and (4) the hydrolysis of ATP. These events must happen in the following order: (1) Ca2+ release, (2) Ca2+ binding, (3) cross-bridge cycling, and (4) ATP hydrolysis.

What are the 6 steps of muscle contraction?

There are six steps of muscle contraction: (1) Excitation, (2) Excitation-Contraction Coupling, (3) Contraction, (4) Relaxation, (5) Refractory Period, and (6) Recovery. (1) Excitation is the first step of muscle contraction and is caused by a nerve impulse or signal from the brain. This signal causes the release of calcium ions from the sarcoplasmic reticulum, which is a network of membranes surrounding the muscle cells. (2) Excitation-Contraction Coupling is the second step of muscle contraction and is the process by which the calcium ions cause the actin and myosin filaments to slide past each other, resulting in muscle contraction. (3) Contraction is the third step of muscle contraction and is when the muscle cells actually contract, or shorten. (4) Relaxation is the fourth step of muscle contraction and is when the muscle cells return to their original length. (5) The Refractory Period is the fifth step of muscle contraction and is the brief period of time after muscle contraction during which the muscle cells cannot contract again. (6) Recovery is the sixth and final step of muscle contraction and is when the muscle cells replenish their energy stores and repair any damage that may have occurred during the contraction.

What are the 11 steps of a muscle contraction?

  1. The 11 steps of muscle contraction are: (1) activation of the motor neuron by an action potential; (2) release of neurotransmitter from the motor neuron at the neuromuscular junction; (3) binding of the neurotransmitter to receptors on the muscle cell membrane; (4) opening of ion channels in the cell membrane; (5) influx of Ca2+ ions into the cell; (6) activation of Ca2+-dependent myosin ATPase; (7) phosphorylation of myosin heads; (8) binding of myosin heads to actin filaments; (9) sliding of actin filaments past myosin filaments; (10) deactivation of Ca2+-dependent myosin ATPase; and (11) release of myosin heads from actin filaments.

What are the 13 steps of muscle contraction?

There are 13 steps of muscle contraction:1. Muscle contraction is initiated by signals from the nervous system.2. The signal from the nervous system triggers the release of calcium from the sarcoplasmic reticulum.3. The calcium binds to troponin, which is a protein found on the thin filaments.4. The binding of calcium to troponin causes the thin filaments to slide past the thick filaments.5. As the thin filaments slide past the thick filaments, the myosin heads attach to the actin molecules.6. The myosin heads then undergo a power stroke, which is a shortening of the myosin head.7. The power stroke causes the actin molecules to be pulled towards the center of the sarcomere.8. The actin molecules are then released from the myosin heads.9. The myosin heads then detach from the actin molecules and return to their original position.10. The calcium is then pumped back into the sarcoplasmic reticulum.11. The troponin then changes shape, which causes the thin filaments to return to their original position.12. The sarcomere then returns to its original length.13. The muscle relaxation is then complete.

What are the 5 steps of the sliding filament theory?

The sliding filament theory is the most widely accepted theory of muscle contraction. It was first proposed by A.F. Huxley in 1954.The theory states that muscle contraction is the result of the sliding of thin filaments within the muscle cell. The filaments are made up of the protein myosin.The sliding of the filaments is thought to be powered by the hydrolysis of ATP. ATP is required for the myosin heads to attach to the filament and produce force.The force produced by the contraction of the filaments is transmitted through the cell membrane to the surrounding tissues.The five steps of the sliding filament theory are:1. ATP binds to the myosin head2. The myosin head attaches to the filament3. The myosin head hydrolyzes ATP to produce energy4. The myosin head uses the energy to move the filament5. The myosin head detaches from the filament

Which is the correct order of events in a contraction?

The correct order of events in a contraction is as follows: the muscles in the uterus contract, which in turn decreases the size of the uterus and helps to expel the fetus. The pressure from the contractions also helps to push the fetus through the birth canal.

What are the 14 steps to muscle contraction?

Muscle contraction is a process that involves a number of steps, all of which are necessary for the muscle to function properly. The steps are:1. The nervous system sends a signal to the muscle.2. This signal is received by the muscle cell.3. The muscle cell responds to the signal by contracting.4. The contraction of the muscle cell produces force.5. This force is transmitted to the tendons, which attach the muscle to the bone.6. The tendons then pull on the bone, causing it to move.7. The movement of the bone produces the desired effect, such as moving the arm or leg.8. The process is then reversed, and the muscle relaxes.9. The relaxation of the muscle allows the bone to return to its original position.10. The cycle then repeats itself, and the muscle can contract again.11. The number of times the cycle repeats itself depends on the amount of force needed.12. The more force that is needed, the more times the cycle will repeat.13. When the muscle is no longer needed, the nervous system will send a signal to stop contracting.14. The muscle will then relax and return to its original state.

Which of the following is the correct order of the phases of a muscle twitch?

There are three phases of a muscle twitch: the latent period, the contraction period, and the relaxation period. The latent period is the time between the stimulus and the start of the contraction. The contraction period is when the muscle contracts and the force is generated. The relaxation period is when the muscle relaxes and the force is removed.

What are the steps of muscle relaxation in order?

  • There are a few different ways that people can relax their muscles, but the most common method is to simply tense and then release the muscle group in question.
  • Start by tensing the muscle group for a count of five, and then release the tension and let the muscle group relax for a count of five.
  • Repeat this process a few times until you feel the muscle group start to loosen and relax.

What is the correct order that a motor nerve impulse travels when triggering a muscle contraction?

The correct order that a motor nerve impulse travels when triggering a muscle contraction is as follows: first, the motor nerve impulse travels from the brain to the spinal cord; then, it travels from the spinal cord to the relevant muscle; finally, it travels from the muscle to the relevant tendon, which triggers the muscle contraction.

What is the process of muscle contraction?

  1. Muscle contraction is the process by which a muscle generates force.
  2. It is a complex process that involves the coordinated action of many different proteins.
  3. The first step in muscle contraction is the release of calcium from the sarcoplasmic reticulum.
  4. This calcium binds to the protein troponin, which is located on the thin filaments of the muscle.
  5. This binding of calcium to troponin causes a conformational change in troponin, which in turn exposes the active site of the protein myosin.
  6. Myosin then binds to the active site of actin, and the two proteins form a cross-bridge.
  7. The binding of myosin to actin causes the myosin head to pivot, which produces a force that is transmitted to the actin filament.
  8. This force is responsible for the contraction of the muscle.
