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.
1 Fascia adherens junctions (anchoring junctions). 2  where actin filaments attach thin filaments in the muscle sarcomeres to the cell membrane. 3  Expanded desmosomes. 4  sites of strong adhesion, that help to keep the muscle cells connected when they contract.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.
