Use the word bank below and match the term with the appropriate definition. Coccontraction Concentric Contraction Contralateral muscles Eccentric Contraction Inhibition Isokinetic Isometric Contraction Isotonic contraction Neutralizing muscles Reciprocal innervation Stabilizing Synergist A. Surround the joint or body part and contact to fixate the area in order to enable another limb or body segment to exert force and move – _____________stabilizing_______ B. Shortening and/or lengthening of muscle fibers under varying degrees of tension – ____isotonic contraction________________ 2

KINE 3300 – Functional Anatomy Neuromuscular and Biomechanics Worksheet C. Occurs when the muscle tissue is lengthened under tension – ______eccentric contraction ______________ D. Times when muscle tension cannot be found in either muscle group due to extremely quick repetition of the same movements – ___________reciprocal innvervation_________ E. Static contraction tension is developed in the muscles but the length does not change – ____isometric contraction________________ F. When the muscle is contracted and shortening occurs within the muscle fibers – ___concentric contraction_________________ G. When both muscle groups on either side of a joint are under tension performing a joint action at a very slow speed against resistance – _____________coccontraction_______ H. Located on the opposite side of the joint from the prime movers – _____contralateral muscles_______________ I. When the stretch reflex of a lengthening antagonistic muscle is dampened due to the concentric contraction of the agonists – ____________________ J. Main function is to rule out undesired motion and aid in refined movement – ________synergists____________ K. Counteract or neutralize the action of another muscle to prevent undesirable movements – ________neutralizing muscles____________ 5. Matching - Use each choice only once. A. Aggregate muscle action B. Agonists C. Amplitude D. Biarticular muscles E. Contractility F. Elasticity G. Extensibility H. Gaster I. Insertion J. Irritability K. Origin 1. Range through which a muscle can change length. _C____ 2. Muscles work in groups rather than independently to achieve a given joint motion. ___A__ 3. Ability of muscle to return to its original length following stretching.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
