Please answer all of this following questions in your own words, thank you. Q1: Which muscles form the quadriceps? How do they function together? Q2: studied the steps of skeletal muscle contraction (sliding filament mechanism). Briefly outline the steps of the sliding filament model of muscle contraction. just mention what is happening with each of the "filaments." Q3: What would be the effect on the muscle if acetylcholinesterase was not present? (8)
Match the appropriate definition to the appropriate vocabulary word. The muscle that contracts and causes the desired action. A. Agonist |The muscle that assist the primer mover that helps generate more force B. Aponeurosis and stablizes the point of origin C. Extensibility D. Smooth muscle E. Cardiac muscle F. Motor-unit recruitment G. Achilles Tendon This muscle relaxes when the primer mover contracts. An example of a connective tissue that connects bone to bone An example of a connective tissue that connects bone to muscle When cold, this organ maintains internal body temperature by repeatably contracting over a short time (i.e. shivering). H. Synergist | This is the ability of muscle tissue to recoil to resting length I. Myofibrils The single unit of muscle tissue J. Fatigue When the tension generated from a single twitch adds to a prexisting tension of a previous twitch in rapid succession. K.

Which of the following are part of the muscle contraction process?(More than one answer may be correct, please aid in answering) Question 5 options: ATP binds and detaches myosin head from actin GTP is hydrolyzed to GDP + P Acetylcholine released into neuromuscular junction by motor neurons Prolactin stimulates the reuptake of ATP. Ca2+ binds to troponin which moves tropomyosin away from actin
QUESTION 8 How does the nervous system grade the force of muscle contraction? O a. Only by recruiting additional motor units O b. Only by varying the firing rate of the motor neurons O c. By varying the firing rate of the motor neurons and by recruiting additional motor units O d. By using more motor neuron pools
Please help in answering this question on toadfish physiology and muscle contractions.
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
What methods can you use to test if someone has more fast twitch versus slow twitch muscle fibers? Remember the variances between fast twitch and slow twitch muscle fibers. Based on this, select a sport and a muscle group primarily used for that sport. Then share which muscle fiber type would be highest for that muscle group.
How is the list below to be properly put in order to describe a muscular contraction? 1. Calcium causes exocytotic release of Acetylcholine into the synaptic gap; all this happens at an area called the neuromuscular junction2. ATP is consumed which allows myosin to "pivot" the myosin head, which pulls actin toward it.3. This process is repeated multiple times and is called the "sliding filament theory".4. Myosin filaments perform "crossbridging".5. Calcium is released and circulated throughout the muscle cell6. The brain predicts the action necessary and decides which muscles and how many "motor units" are needed to perform that action.7. Tropomyosin moves to reveal the active site of the F-Actin strand8. Upon reception of a calcium ion, the Troponin complex becomes activated9. Proteins embedded in the Sarcolemma receive enough of the ACH neurotransmitter to generate an electrical impulse.10. The electrical impulse is perpetuated throughout the muscle fiber.11. A nervouse impulse is…
Based on what you know about the neuromuscular junction and muscle contraction, describe very specifically how Botox injections cause localized muscle weakness/paralysis.
Question 2 During which step of a muscle contraction cycle is ATP needed? when myosin head does a power stroke and release of calcium ions into sarcoplasm when myosin head detaches from actin and release of calcium ions into sarcoplasm when myosin head does a power stroke and pumping of calcium ions back into SR when myosin head detaches from actin and pumping of calcium ions back into SR
