In mathematics, the Fibonacci numbers or Fibonacci series or Fibonacci sequence are the numbers in the following integer sequence: (sequence A000045 in OEIS) By definition, the first two numbers in the Fibonacci sequence are 0 and 1, and each subsequent number is the sum of the previous two.
Tight Junctions. Tight junctions are found predominantly in epithelial tissues, such as intestinal brush border. Water and other fluids must be prevented from leaking between adjacent cells, so that body fluids do not gradually seep across the intestinal lining.
Muscle: Cell Junctions. There are several kinds of cell-cell junctions. A description of these can be found here. Cardiac cells are special, amongst the muscle types, because they are connected to each other by intercalated discs-structures that are only found in cardiac muscle cells.ntercalated discs contain. different types of cell-cell junctions: 1  Fascia adherens junctions (anchoring junctions). 2  where actin filaments attach thin filaments in the muscle sarcomeres to the cell membrane.
