The urine in your bladder is unable to pass out of the bladder through its epithelial lining. Which type of junction exists between these cells?

A) tight junction
B) basement membrane
C) gap junction
D) adhesion junction
E) There is no special junction between these cells.

Tight Junction

Junction between cells when adjacent plasma membrane proteins join to form an impermeable barrier.

Basement Membrane

A thin, fibrous structure that lies underneath epithelial cells, providing support and anchorage, and acting as a barrier against the spread of cells.

Gap Junction

Junction between cells formed by the joining of two adjacent plasma membranes; it lends strength and allows ions, sugars, and small molecules to pass between cells.
