11. Arrange the following in statements in the order that they occur, by adding a number: nf.e ACh is released into the synaptic cleft The action potential, carried deep into the cell, causes the sarcoplasmic reticulum to release calcium ions The muscle cell relaxes and lengthens ACh diffuses across the synaptic cleft and binds to receptors on the plasma membrane of the muscle cell The calcium ion concentration at the myofilaments increases, the myofilaments slide past one another, and the cell shortens Depolarization occurs, and an action potential is generated As calcium is actively reabsorbed into the sarcoplasmic reticulum, its concentration at the myofilaments decreases

If Ca2+ pumps of the sarcoplasmic reticula fail to function, what will happen to the tension generated in a single muscle fiber when it is excited? increase in tension decrease in tension no change in tension
3.4. About human skeletal muscle contraction, what are the correct statements? PHYSIOLOGY_basic (OJO) A muscle fiber is made by the parallel apposition of sarcomers. Generation of force relies on the formation of cross-bridges between actin and myosin filaments. In the process of contraction, adenosine triphosphate (ATP) is required both to drive the actin-myosin association-dissociation cycle and to recycle calcium back to the endoplasmic reticulum. Each muscle fiber is innervated by one neuron only. T tubules are plasma membrane invaginations of the sarcolemma that allow excitation-contraction coupling.
Using pyramidal motor tract as a template, describe the voluntary control of skeletal muscles being sure to use appropriate course terminology. Start from the very first neuron and end with neural innervation onto muscle fiber.
When motor units are recruited to participate in tension development in a muscle, the order of recruitment is typically: Question 13 options: from slow twitch to fast twitch from fast twitch to slow twitch it depends on the type of contraction related to the size and shape of the muscle

As an action potential moves along the sarcolemma, the brief opening of voltage-gated Na+ channels will allow Na+ to rush into the muscle cell, causing the inside of the membrane at that location to become more ________. positive negative
Which of the following regions of a sarcomere does not change length during a contraction because it represents the length of the thick myosin filaments. Group of answer choices Z disk H band A band I band
During muscle contraction, the ion that leaks out of the sarcoplasmic reticulum and induces myofibrils to contract is O Na+. O Mg2+. O Cksup>-. O K+. O Ca2+.
What happens when the muscular action potential spreads through transverse (T) tubules of the sarcolemma? The action potential in T tubules triggers the release of acetylcholine from the axon terminals of the motor neuron. The action potential in T tubules triggers closing of sodium channels and opening of potassium channels, which enables myosin cross bridges to form. The action potential in T tubules opens voltage-sensitive calcium channels in the T tubules, allowing calcium to flow into the sarcoplasm. The action potential in T tubules causes a shape change in voltage-sensitive proteins that pull open calcium channels in the sarcoplasmic reticulum.
What type of action potential conduction is found on the surface of skeletal muscle cell? continuous conduction saltatory conduction the most common cause of muscle cramps is low potassium. True :/ false
Why does continuous calcium release within a muscle fiber cause greater tension? OActivates more calcium pumps O Activates myofibrils continuously Increases action potential frequency Lengthens sarcomere O Calcium makes the muscle fiber an offer it can't refuse
