<prompt> Nerve supply of ciliary muscles for pupil accommodation is:Parasympathetic and sympathetic systemSomatosensory nucleusTrigeminal nerveRed Nucleus of mid brain  <response>: The ciliary muscle receives parasympathetic fibers from the short ciliary nerves that arise from the ciliary ganglion. The sympathetic postganglionic fibers are part of cranial nerve V1 Nasociliary nerve of the trigeminal, while presynaptic parasympathetic fibers to the ciliary ganglia are from the oculomotor nerve.
