Is this effect linear? c) What stretch resulted in the highest contraction force? What happens to the muscle at the highest stretch levels?arrow_forward
- A) Assuming that each individual muscle fiber generates the same amount of tension, which of the following skeletal muscles will produce the greatest amount of overall tension when fully stimulated? Muscle Total Number of Muscle Fibers in Muscle A 150 B 1000 C 600 Group of answer choices Muscle A Muscle B Muscle C B)The following list of events take place during a muscle contraction. Place the events in chronological order as they relate to a muscle contraction. Calcium is released from the sarcoplasmic reticulum. Myosin heads bind to actin. An action potential arrives at the axon terminal of a motor neuron. Calcium binds to troponin, displacing tropomyosin and exposing myosin head binding sites on actin. Myosin heads undergo power stroke and actin slides over myosin towards M line of sarcomere. Acetylcholine is released at the neuromuscular junction.arrow_forwardMuscular strength is defined as the: a) ability of a muscle to contract with maximal force O b) ability to move the joints through a full range of motion O c) ability to sustain a given level of muscular tension over time d) amount of force a muscle can produce repeatedly over 60 secondsarrow_forwardWhat creates the striated appearance of a skeletal muscle cells?arrow_forward

O a) skeletal muscle has striations O b) skeletal muscle is attached to bones O c) skeletal muscle is under voluntary control O d) skeletal muscle is multinucleated O all of the above O b, c, & d but not aarrow_forward3) List and define the organizational structure of skeletal muscle beginning with the sacrcomere up ABC to a whole muscle. 4) Explain the differences between the zones and bands of a sarcomere. 5) List and explain the differences between contractile and non-contractile proteins. 6) What are the agonists, synergists, and antagonists to go from sitting to standing from a chair. 7) Provide an every day example of each of the 3 types of muscle actions. Name the muscle involved as well as the movement. 8) Why do we store energy as ATP and resynthesize it, instead of just storing all we need. 9) What are the differences between resting, steady state, and maximal metabolic rate? 10) Why would someone measure arm circumference? How would that be helpful? 11) MRI results in a grayscale of 0 (black) to 256 (white) for each pixel of tissue. How do we tell the difference between different types of tissue in the cross section of a limb (arm or leg, e.g. what's the difference between muscle and fat,…arrow_forward16) when a skeletal muscle contracts, it usually moves the bone at one end much more than the bone at its other end. The attachment of the muscle to the less moveable bone is called its a) insertion b) ligament c) origin d) flexorarrow_forward
