Artwork for tight and gap cell junctions
Illustrations of structural models for tight (left) and gap intercellular junctions. The plasma membranes of certain neighbouring cells are arranged so that the cells may interact in a specific way. Tight junctions (zonula occludens) serve to seal the space between cells. Intestinal cells are separated by these " seam welds", which ensure that the intestinal contents passes through the cells rather than between them. The gap junction or nexus is a form of macula occludens that provides a restricted channel between the cytoplasm of one cell and its neighbour, through which small molecules may pass

EDITORS COMMENTS
This print showcases the intricate artwork of tight and gap cell junctions, providing a visual representation of their structural models. The plasma membranes of neighboring cells are strategically arranged to facilitate specific interactions between them. On the left side, we observe the tight junctions, also known as zonula occludens, which act as sealants between cells. These "seam welds" play a crucial role in intestinal cells by ensuring that contents pass through the cells rather than seeping between them. In contrast, on the right side of the image, we witness the fascinating gap junction or nexus – a type of macula occludens. This unique intercellular junction forms a restricted channel connecting one cell's cytoplasm with its neighbor's cytoplasm. Through this channel, small molecules can traverse from one cell to another. The illustration not only highlights these essential biological structures but also emphasizes their significance in various fields such as biology, microbiology, cytology, and cell structure studies. It serves as an educational tool for scientists and students alike who seek to understand cellular mechanisms at a microscopic level. Captured by Science Photo Library without any commercial intentions behind it; this remarkable artwork invites us into the mesmerizing world of cellular interactions and reminds us how intricately nature has designed even our tiniest building blocks - our cells.
