What does zonula mean?

Zonula occludens (tight junction). This is the most apical (closest to the top) of all the cell-cell junctions. It is a super-tight junction – in fact, for a long time, people thought that adjacent membranes were fused together in this junction (they’re not, but they sure look like they are). A few things of note:

What are the zonules of the eye?

The ciliary epithelial cells of the eye probably synthesize portions of the zonules. The zonule of Zinn is split into two layers: a thin layer, which lines the hyaloid fossa, and a thicker layer, which is a collection of zonular fibers. Together, the fibers are known as the suspensory ligament of the lens. The zonules are about 1–2 μm in diameter.

What is zonule of Zinn?

The upper half of a sagittal section through the front of the eyeball. (Zonule of Zinn visible near center.) [edit on Wikidata] 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.
