Final answer:
The fascicles that run along the long axis of the muscle have a parallel organizational pattern, which is common in skeletal muscles and affects the muscle's force and range of motion.
Step-by-step explanation:
The organizational pattern of the fascicles in a muscle where they run along the long axis of the muscle is parallel. This arrangement is common in the majority of skeletal muscles. Parallel muscles may vary in shape, some being flat, while others have a spindle-shaped central body, also known as the muscle's belly. The belly becomes more pronounced when the muscle contracts. This organizational pattern is essential as it correlates with the muscle's force generation and range of motion.
