Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are the important contractile proteins involved in muscle action. Muscle contraction, in addition to movement, serves several other important functions in the body, including posture, heat generation, and joint stability. Muscle contraction maintains posture, which includes standing and sitting.

Figure 38.37 Which of the following statements about muscle contraction is true? The power stroke occurs when ATP is hydrolyzed to ADP and phosphate. The power stroke occurs when ADP and phosphate dissociate from the myosin head. The power stroke occurs when ADP and phosphate dissociate from the actin active site. The power stroke occurs when Ca2+ binds the calcium head.
The term applied to the movement of lifting your body up onto you "tippy toes" is referred to as: Question 20 options: dorsiflexion pronation hyperextension plantar flexion Question 21 How can the force of an eccentric contraction be described? Question 21 options: the strongest type of contraction stronger than an isometric contraction, but weaker than a concentric contraction the weakest type of contraction stronger than a concentric contraction, but weaker than an isometric contraction
The sliding filament model of contraction is a theory that is used to explain how muscles contract to cause movement. The theory explains that the change in the length of the muscle during contraction is due to the sliding of the myofilaments past each other and not to a change in the length of either of the myofilaments.
Arrange the following in statements in the order that they occur during muscle contraction: 1-10 ACh leaves the synaptic knob and enters the synaptic cleft The action potential is carried deep into the muscle cell by T tubules The muscle cell relaxes and lengthens Myosin binds to and pulls on actin, resulting in muscle shortening Calcium attaches to troponin As calcium re-enters the sarcoplasmic reticulum, its concentration at the myofilaments decreases Calcium is released from the sarcoplasmic reticulum Tropomyosin rolls out of the way, exposing actin ACh diffuses across the synaptic cleft and attaches to protein receptors on the sarcolemma, resulting in muscle "excitation" Na+ enters the muscle cell and K+ exits, resulting in an action potential
Which among the four choices below is NOT a typically way to measure muscle strength? Maximum force that can be exerted during an isometric contraction Maximum load that can be lifted at once Peak torque during an isokinetic contraction Number of repetitions before muscle fatigue sets in
You can choose one or more than one option About human skeletal muscle contraction, what are the correct statements? PHYSIOLOGY basi:. 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 tubules are plasma membrane imaginations of the sarcolemma that allow excitation-contraction coupling Arginase is an enzyme that : BIOCHEMISTRY advanced is expressed in the cytoplasm of hepatocytes shows two isoenzymes in mammals. found in the liver and other tissues catalyzes the formation of urea and ornithine from arginine. induces hyperammonemia when it is overexpressed is inhibited by basic amino acids such as lysine and ornithine.…
