Making a Muscle Activity 1. Separate a twizzler by pulling apart the strands. Each strand will represent a muscle fiber, also known as a muscle cell. 2. Wrap each of the strands of that twizzler individually in a piece of plastic wrap leaving extra plastic wrap at each end. The plastic wrap represents that each muscle fiber is covered in a connective tissue called endomysium. 3. Now, take 1/3 of the individually wrapped muscle fibers and wrap them using another piece of plastic wrap. The bundle is called a fascicle and the plastic wrap is a connective tissue covering is called perimysium. 4. Create two more fascicles with the remaining muscle fibers. 5. Put all of your fascicles together and wrap them with another layer of plastic wrap. This will create a single muscle and its covering is called epimysium. Between fascicles there are blood vessels. 6. The ends of the outer plastic wrap represent a tendon that would be connected to a bone. Use your model to label the diagram (Use all 8 underlined words from above):
