  • Fiber to the eye

    Fiber to the eye

    The zonule of Zinn (/ ˈtsɪn /) (Zinn's membrane, ciliary zonule) (after Johann Gottfried Zinn) is a ring of fibrous strands forming a zonule (little band) that connects the ciliary body with the crystalline lens of the eye. The Zonular fibers are viscoelastic cables, although their component. The eyes act as the initial point of contact through which photons pass to access the visual pathway. The visual pathway refers to the anatomical structures responsible for the conversion of light energy into electrical action potentials that can be interpreted by the brain. In humans, the fibers transmit forces that flatten the lens during the process of disaccommodation, thereby bringing distant objects into focus.
