Now you want to focus on exercises to increase power. You would choose which of the following exercises? Question options: Concentric strengthening Eccentric strengthening Stretches It doesn't matter; any of the above will help increase power. Question 7 2 / 2 points Most concentric exercises done in the body are considered to be which type of lever? Question options: First class Second class Third class Fourth classQuestion 8 2 / 2 points If the distance of a force arm (FA) is 4 feet and the resistance arm (RA) is 2 feet, then the mechanical advantage would be Question options: 1/2 1/4 8 2 Question 9 2 / 2 points The innermost layer of the protective membrane that contains the blood vessels to the brain is the Question options: dura mater subarachnoid mater pia mater ventricular mater Question 10 2 / 2 points In order to increase the challenge of a person working on balance, you could do which of the following? Question options:Raise the center of gravity and increase the base of support Raise the center of gravity and decrease the base of support Lower the center of gravity and increase the base of support Lower the center of gravity and decrease the base of support Question 11 2 / 2 points At which level of the spinal column is damage to the spinal cord no longer a concern? Question options: C7 T8 T10 L1 Question 12 2 / 2 points A common pathology of the PNS characterized by weakness of the long thoracic nerve is which of the following? Question options: Scapular winging Thoracic outlet syndrome Bell's palsyCarpal tunnel syndrome Question 13 2 / 2 points A person with "wrist drop" has damage to which of the following nerves? Question options: Radial nerve Median nerve Femoral nerve Common peroneal nerve Question 14 2 / 2 points What is the term for a muscle contraction in which the proximal end moves toward the distal end? Question options: Irritability Extensibility Reversal of muscle action Active insufficiency Question 15 2 / 2 points Which of the following is NOT true of an eccentric contraction?Question options: Contraction produces a greater force than a concentric contraction. Contraction is used as an acceleration activity. Muscle attachments move farther apart. Movement occurs with gravity.

Question options: Irritability Contractility Extensibility Elasticity Question 17 2 / 2 points A person experiencing "ape hand" has damage to which of the following nerves? Question options: Radial nerve Median nerveFemoral nerve Common peroneal nerve Question 18 2 / 2 points A muscle that generates most of its force directed back into the joint is producing which type of force? Question options: Angular force Stabilizing force Dislocating force Force couple Question 19 2 / 2 points The "stress-response" and stimulation part of the autonomic nervous system (ANS) is the sympathetic nervous system. Question options: True False Question 20 2 / 2 points The deltoid muscle can effectively contract through its entire ROM because of the upward rotation of the scapula, which serves to maintain tension in the deltoid muscle. If the deltoid loses tension, it becomesQuestion options: passively insufficient actively insufficient noncontractile None of the above Question 21 2 / 2 points A person with weakness of knee extension has damage to which of the following nerves? Question options: Radial nerve Median nerve Femoral nerve Common peroneal nerve Question 22 2 / 2 points The reason that a large-handled object is easier to turn is that the mechanical advantage is larger. Question options: True FalseQuestion 23 2 / 2 points Which of the following is a true statement regarding oblique muscle fibers? Question options: Oblique muscle fibers tend to be longer than parallel fibers, thus having more strength potential than parallel fibers. Oblique muscle fibers tend to be longer than parallel fibers, thus having less strength potential than parallel fibers. Oblique muscle fibers tend to be shorter than parallel fibers, thus having more strength potential than parallel fibers. Oblique muscle fibers tend to be shorter than parallel fibers, thus having less strength potential than parallel fibers. Question 24 2 / 2 points The majority of lower extremity functional activity occurs in a closed chain manner. Question options: True False Question 25 2 / 2 points Two forces acting in equal but opposite directions and resulting in a turning effect is called a Question options: stabilizing force dislocating forcemoment of force force couple
