Does the autonomic nervous system, or the somatic nervous system controll intrinsic eye muscles?
The intrinsic eye muscles are located within the eye and are classified as smooth involuntary muscle.They control the diameter of the pupil and the shape of the lens. The intrinsic eye muscles are innervated by the autonomic systems and include the iris sphincter and the ciliary muscle (innervated by the parasympathetic component of cranial nerve III), and the radial pupillodilator muscles (innervated by the ascending cervical sympathetic system with its long course from spinal segments T1 through T3). Hope that helps.
