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.
First, explain how resting membrane potential is established in terms of ion concentration and electric charge. Next, explain the process of neural signal transmission from an alpha motor neuron to the muscle fiber. Do this by explaining how an AP is generated (ions and membrane proteins) at the neuron, how the signal is propagated, what happens at the axon terminal, what happens at the motor endplate, and explain all the molecular events that occur to cause muscle contraction.
Skeletal muscle fibres are very metabolically active and are adapted to create a lot of ATP from aerobic cellular respiration. Additionally, cells require other things to stay alive. Explain how the following three organ systems contribute to allowing a muscle cell to carry out its roles: a) Respiratory system b) Cardiovascular system c) Gastrointestinal system asap please.
Tropmyosin and Troponin are called the regulatory proteins in muscle contraction. Describe the myofibril organization and specific structural and functional role of these two proteins in muscle contraction-relaxation cycle.
Vhat are the two types of muscle movement categories? Give an example for both. Describe Swammerdam's experiment and Galvani's experiment with frog legs. What did they tell us about muscle contraction? What is the sliding-filament model for muscle contraction? Describe the role of actin and myosin of sarcomeres in the model (be specific). Describe how an action potential triggers muscle contraction. Know the specific molecules involved. . Describe the structural and functional differences between smooth, cardiac and skeletal muscles. What are the three types of skeletal muscle fibers and how do they differ in structure and function? Next « Previous MacBook Pro
Muscles typically shorten when they contract. Explain the three ways by which they return to their resting length, and then, explain why keeping your muscle connective tissues (endo-, peri-, and epimysium) stretched and pliable is so important for muscle function. Be specific and provide examples.
