Question

Quizplus · Accepted Answer

The radial muscle of the iris is only innervated by the sympathetic nervous system, not the parasympathetic nervous system, which is responsible for controlling the circular muscle of the iris. Thus, the radial muscle of the iris is not dually innervated. Salivary glands, urinary bladder, pancreas, and bronchioles in the lungs are all dually innervated.
