The function of transverse tubules is to rapidly move action potentials to the interior of the muscle fiber.

Explanation:

The function of the transverse tubules is to bring the action potential of the sarcolemmal cell membrane to the sarcomeres, where the contractile machinery of the muscle fiber is organized.
