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.

What is the difference between tight junctions and gap junctions? A gap junction is like a ' tunnel ' in between cells where messages and nutrients can be passed back and forth. A tight junction is the connection between two cells that are s â¦ trongly ' sown ' together with protein threads to help maintain tissue arrangment.
