REVIEW ACTIVITIES Coloring Activity 1. This is a resting sarcomere. Draw vertical lines through the sarcomere to divide it into the regions listed below. 2. Color each region a different color. 3. Draw a contracted sarcomere directly below this sarcomere and continue your vertical lines and coloring scheme to illustrate the changes in the regions.

Correctly label the different bands of a sarcomere. Z disc band Sarcomere H band M line A band Contains both thick and thin filaments I band H band Z disc Reset
What are the positions of actin and myosin molecules in the sarcomere before and during the muscle contraction?
Why is the starting length of the sarcomere important with respect to generating a force (i.e., the length-tension relationship.)? Explain in detail
Draw a sarcomere and identify the different bands and zones. Identify the kinds of fibers contained within each zone.
Why does the force output of muscles change with length? Draw a diagram of a sarcomere detailing your explanation.
Muscle contraction: Select one O a occurs when myosin pulls on actin and the sarcomere shortens b. occurs when actin pushes on myosin and the sarcomere elongates O c occurs when the myosin tail splits the actin filament in half Od occurs when actin and myosin entangle, generating more distance between Z lines
