Examples

  • For the first time, scientists have linked the growth of new brain cells–induced by a compound known as ciliary neurotrophic growth factor CNTF–with weight loss in mice.

  • As the choroid approaches the front part of the eyeball, its parts become folded upon themselves into a series of ridges, called ciliary processes.

    A Practical Physiology

  • In addition to differentiated retinal cells, the amphibian eye contains a population of self-renewing retinal stem cells located in the retinal periphery in a region called the ciliary marginal zone or CMZ.

    PLoS Biology: New Articles

  • You have a muscle in your eye called the ciliary muscle, that contracts to make the eye’s lens fatter and able to zoom in to objects closer up.

    Shock of Gray

  • In doing so it had cleared all the gunk from my arteries, tweaking my ciliary muscles so my eyesight is as good as anyone's, and generally made me into the healthiest human being on the planet.

  • We vertebrates have ciliary cells, c-opsin, and a phosphodiesterase pathway.

    PZ Myers - The Deepest Links (on Evolution)

  • In our eyes, we primarily use the ciliary photoreceptors for vision, but we also maintain a set of rhabdomeric photoreceptors that have the job of sensing light to set circadian rhythms.

    PZ Myers - The Deepest Links (on Evolution)

  • Some invertebrates also have both, but they use the rhabdomeric receptors for vision and the ciliary receptors for circadian rhythms.

    PZ Myers - The Deepest Links (on Evolution)

  • Modifications from the full body covered norm include a single ring of cilia, grouped ciliary organelles called cirri, and restriction of cilia to feeding tentacles.

    Protozoa

  • Small turbellarians use waves of ciliary action for locomotion to glide over surfaces, whereas larger species use muscular movements of their entire body to creep, swim, twist or somersault along the substrate.
