Hiccups usually stop within a few minutes to a few hours. Hiccups that last longer than 48 hours are called persistent hiccups. Hiccups that last longer than a month are called intractable hiccups. While very rare, intractable hiccups can cause exhaustion, lack of sleep, and weight loss.
Gap junctions. Gap junctions. connections between cells which allow passage of small molecules and electric current. Gap junctions were first described anatomically as regions of close apposition between cells with a narrow (1-2 nm) gap between cell membranes. The variety in the properties of gap junctions is reflected in the number of connexins, the family of proteins which form the junctions.

Cell junctions can be divided into two types: those that link cells together, also called intercellular junctions (tight, gap, adherens, and desmosomal junctions), and those that link cells to the extracellular matrix (focal contacts/adhesion plaques and hemidesmosomes).ight Junctions. The tight junction (also referred to as a zonula occludens) is a site where the membranes of two cells come very close together. In fact, the outer leaflets of the membranes of the contacting cells appear to be fused.
