Final answer:
Smooth muscles with fascicles running along the long axis of the muscle have a longitudinal arrangement.
Step-by-step explanation:
Smooth muscles have a variety of arrangements based on the direction of their fascicles. In the context of the question, a muscle with fascicles running along the long axis of the muscle has a longitudinal fascicle arrangement. This means that the smooth muscle fibers are aligned parallel to the muscle's long axis.
For example, smooth muscles in the digestive, reproductive, and respiratory tracts have a longitudinal arrangement, which allows them to contract and relax to push substances through these organs.
In summary, the smooth muscle arrangement that corresponds to fascicles running along the long axis of the muscle is longitudinal.
