| zonula adherens | <cell biology> Specialised intercellular junction in which the membranes are separated by 15-25nm and into which are inserted microfilaments. Similar in structure to two apposed focal adhesions, though this may be misleading. Microfilaments inserted into the zonula adherens may interact (via myosin) with other microfilaments to generate contraction. Constitute mechanical coupling between cells. (18 Nov 1997) |

| fascia adherens | A broad intercellular junction in the intercalated disk of cardiac muscle that anchors actin filaments. (05 Mar 2000) |
| zonula | A small zone. Synonym: zonula. (05 Mar 2000) |
| zonula ciliaris | A series of delicate meridional fibres arising from the inner surface of the orbiculus ciliaris that run in bundles between, and in a very thin layer over, the ciliary processes; at the inner border of the corona, the fibres diverge into two groups that are attached to the capsule on the anterior and posterior surfaces of the lens close to the equator; the spaces between these two layers of fibres are filled with aqueous humor. Synonym: zonula ciliaris, apparatus suspensorius lentis, suspensory ligament of lens, Zinn's zonule. (05 Mar 2000) |
| zonula occludens | <cell biology> Specialised intercellular junction in which the two plasma membranes are separated by only 1-2nm. Found near the apical surface of cells in simple epithelia, forms a sealing gasket around the cell. Prevents fluid moving through the intercellular gap and the lateral diffusion of intrinsic membrane proteins between apical and baso lateral domains of the plasma membrane. (18 Nov 1997) |
