These structures are commonly interrupted by using 1-heptanol or the ulcer drug carbenexolone, and in the juxtaglomerular apparatus these structures are present between mesengial cells. Synchronization via these structures in the Islets of Langerhans are responsible for insulin oscillations, and the ventral tegmental area contains GABAergic cells with these structures. Also located in the cerebellum and between astrocytes in order to create a syncytium, these structures contain two hexamers of connexin proteins attached to each other. They are used to transport ions and small molecules between cells and are used to electrically synchronize cells more quickly than a traditional synapse would be able to. For 10 points, name these intracellular connection present between cardiac muscle tissue.
