Final answer:
The appearance and function of skeletal muscle are influenced by the arrangement of fascicles, the number of muscle cells in a motor unit, and the presence of connective tissues like perimysium and endomysium.
Explanation:
The appearance and function of skeletal muscle are influenced by the arrangement of the pattern of fascicles, the number of muscle cells in a motor unit, the presence of perimysium around fascicles, and the presence of endomysium around muscle cells. The arrangement of fascicles impacts muscle force generation and range of motion, while the perimysium and endomysium support muscle fibers and provide pathways for nerves and blood vessels.
