She was a hard taskmaster, too, for she looked down with loathing and contempt upon the misshapen creatures amongst which cruel Fate had thrown her and to some extent vented upon them her dissatisfaction and her thwarted love.
Making the world better, one answer at a time. 1. Tight Junctions = tight, zipper-like junctions between cells; prevent intercellular passage of materials; 2. Desmosomes = anchoring junctions that hold adjacent cells together; 3. Gap Junctions = communicating (transport) channels between adjacent cells.
Graphic of junctions in animal cells. Tight junctions. Tight junctions block the flow of fluids between epithelial cells. For example, the cells that line the intestine are responsible for taking up nutrients from the gut. The nature of the material taken up must be controlled to block unwanted substances from entering our bodies. The control comes from the fact that materials must pass through receptors on the epithelial cell membranes. Tight junctions form a water tight seal and prevent material from passing between cells.
