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,…
List the three types of skeletal muscle fibers, and describe theanatomic and functional characteristics of each.
a) Describe how the isolated muscle behaved as it was stretched progressively.
b) What effect does stretching the muscle have on contraction strength? Is this effect linear?
c) What stretch resulted in the highest contraction force? What happens to the muscle at the highest stretch levels?

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_forward
