The specialized soft-tissue manipulation technique used to ease the pain of conditions such as fibromyalgia, movement restrictions, and temporomandibular joint disorders is known as ____________________________ myofascial release occupational therapy RICE therapeutic ultrasound

Why do you think a person is able to perform anaerobic exercise (such as lifting and holding a heavy weight) only briefly but can sustain aerobic exercise (such as walking or swimming) for long periods? (Hint: Muscles have limited energy stores.)

Depolarization of the sarcolemma means ________. the inside of the membrane has become Less negative as sodium ions accumulate the outside of the membrane has become less negative as sodium ions accumulate the inside of the membrane has become more negative as sodium ions accumulate the sarcolemma has completely lost any electrical charge

The elbow is an example of which type of joint? hinge pivot saddle gliding

Watch this video (http://openstaxcollege.org/l/flexext) to learn more about the flexion and extension of the knee, as the femur both rolls and glides on the tibia to maintain stable contact between the bones in all knee positions. The patella glides along a groove on the anterior side of the distal femur. The collateral ligaments on the sides of the knee become tight in the fully extended position to help stabilize the knee. The posterior cruciate ligament supports the knee when flexed and the anterior cruciate ligament becomes tight when the knee comes into full extension to resist hyperextension. What are the ligaments that support the knee joint?

What is a motor unit? Why does a rapid series of muscle twitches yield a stronger overall contraction than a single twitch?

Which arrangement best describes a bipennate muscle? The muscle fibers feed in on an angle to a long tendon from both sides. The muscle fibers feed in on an angle to a long tendon horn all directions. The muscle fibers feed in on an angle to a long tendon horn one side. The muscle fibers on one side of a tendon feed into it at a certain angle and muscle fibers on the other side of the tendon feed into it at the opposite angle.
