Medical Definition of Zonula adherens
1.
| 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.
