ZOO 3731 Study Guide - Final Guide: Skeletal Muscle, Anatomical Terms Of Motion, Homeostasis
Document Summary
Now that you understand the concept of origins & insertions, think about where a muscle must be located and what it must attach to in order to be able to perform a particular action (or vice versa). Amanda sanchez, heder garcia, daniela pantoja, jenifer alvarez, brianna wint. Posterior hip wrist flexion hyperextension or extension humerus ulna/radius anterior. Place the following muscle contraction events in the correct order. Tropomyosin to roll away from the active sites on actin and expose them for binding. The myosin head returns to its resting state. Myosin binds to the active sites on the actin molecules. Tropomyosin (blue ribbons) covers up the active sites. The myosin head pivots, pushing the thin filaments (actin, tropomyosin, troponin) closer together. Atp is needed to release the myosin head from the actin molecule. 8 a. wrapping b. multipennate c. convergent d. parallel e. circular f. unipennate g. parallel with tendinous bands h. bipennate.
