The barrier that separates the interstitial fluid from the intracellular fluid is the plasma membrane. The interstitial fluid is a major component of the extracellular fluid.

Perilymph is an extracellular fluid located within the cochlea (part of the ear) in 2 of its 3 compartments; the scala tympani and scala vestibuli. The ionic composition of perilymph is comparable to that of plasma and cerebrospinal fluid. The major cation of perilymph is sodium.
The body is made up of three major extracellular materials. These materials are; body fluids, cell secretions and extracellular matrix.
The most abundant positive ion or cation in the extracellular fluid is sodium (Na+). Chloride (Cl-) is the most abundant negative ion or anion.
Extracellular fluid is the body fluid outside the cell that is composed of blood plasma, interstitial fluid, lymph and transcellular fluid. It resides outside the cells and transports mmaterials to and from the cells
