Question 1

Put these myofibers in the order they would be recruited as the body moves from a weak to a strong stimulus:
1. glycolytic fast-twitch fibers
2. fatigue-resistant oxidative fast-twitch fibers
3. fatigue-resistant slow-twitch fibers
◦ 1, 2, 3
◦ 1, 3, 2
◦ 2, 3, 1
◦ 3, 2, 1
◦ 3, 1, 2

Question 2

An important difference between single-unit and multiunit smooth muscle is the
◦ numerous gap junctions in single-unit smooth muscle, which allow many cells to work together as a sheet.
◦ ability of single-unit fibers to change into multiunit fibers when needed.
◦ closely controlled individual fibers in single-unit smooth muscle to allow fine control and graded contractions by selective activation.
◦ longer actin and myosin filaments in multiunit smooth muscle, which allow coordination of contraction.
