The zonule of Zinn (/ ˈ t s ɪ n /) (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 ciliary ring is a fibrous ring flattened against the sclera externally and the vitreous humour or vitreous body internally. The aqueous humor from the anterior chamber of the eye pours through these free spaces and reaches the inner surface of the canal of Schlemm. Here we review the structure and function of the specialized primary cilia of hair cells, termed kinocilia, found in the mammalian auditory system. It has a specialized function in the uveal tract; it produces aqueous humor, facilitates trabecular outflow, intervenes in alteration of the shape of the crystalline lens during accommodation, and secretes hyaluronic acid into the vitreous. It also contains the ciliary muscle, which changes the shape of the lens when your eyes focus on a near object.
