• All around the edge, where the cornea, sclerotic, and choroid meet, is a ring of involuntary muscular fibers, forming the ciliary muscle. 

• To flatten the lens, the ciliary muscle relaxes, the elastic force of the eyeball resumes its tension on the suspensory ligament, and the membranous capsule resumes its pressure on the sides of the lens. 

• While the greater portion of the eyeball is concerned in the focusing of light, the crystalline lens, operated by the ciliary muscle, serves as the special instrument of accommodation. 

• This ganglion mediates both the pupillary light reflex and visual accommodation through its control of the iris and ciliary muscle, respectively.

• Anterogradely labeled terminals in the visual sensory nuclei, indicating tracer spread from the ciliary muscle to the retina, were present in both cases.

• It is similarly apparent that spread to the iris may have occurred following injections of the ciliary muscle.

• In contrast, those cells located caudally, dorsal and ventral to the oculomotor nucleus, control the ciliary muscle.
