Specialized cell membrane structures that decrease electrical resistance between the cells allowing action potentials to pass efficiently from one cell to adjacent cells are the

D: Gap junctions are a specialized intercellular connection between a multitude of animal cell-types. They directly connect the cytoplasm of two cells, which allows various molecules, ions and electrical impulses to directly pass through a regulated gate between cells. A: Extensive capillary networks allows the abundant supply of oxygen and nutrients on tissues such as skeletal muscle, liver and kidney. B: Intercalated disks support synchronized contraction of cardiac tissue. They occur at the Z-line of the sarcomere and can be visualized easily when observing a longitudinal section of the tissue. C: Mitochondrion is an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur.
