25
material outside the nucleus and inside the plasma membrane
cytoplasm
26
membrane junction that is impermeable, leak-proof sheets
tight junction
27
membrane junction anchoring that prevents cells from being separated
desmosomes
28
membrane junction allow communication between cells through connexons that span the two cell membranes
gap junctions
29
fluid containing nutrients dissolved in water that suspends other elements
cytosol
30
metabolic machinery of the cell
organelles
31
a thin layer of fluid which surrounds the body's cells. Interstitial fluid has become useful in the monitoring of glucose levels in people with diabetes.
