The Chief Extracellular cation is sodium.
Sodium (Na+) is the major extracellular cation in the body, playing a significant role in maintaining fluid balance, nerve function, and muscle contractions.

Sodium is the primary cation for ECF, potassium is the primary cation for ICF.
The primary extracellular fluid cation in the body is sodium (Na+). It plays a crucial role in maintaining fluid balance, nerve function, and muscle contraction.
Major Intracellular cation - K+ (Potassium) Major Extracellular cation - Na+ (Sodium) Major Intracellular anion - PO4+ (Phosphate) Major Extracellular anion - Cl- (Chloride)
The principal cation of the extracellular fluid (ECF) is sodium (Na+). Sodium plays a critical role in maintaining fluid balance, nerve function, and muscle contraction in the body.
The three major subdivisions of extracellular fluid in the body are interstitial fluid, plasma, and transcellular fluid. Interstitial fluid surrounds cells, plasma is the fluid component of blood, and transcellular fluid is found in cavities such as cerebrospinal, synovial, and peritoneal fluids.
Sodium ion is the most concentrated ion in the extracellular fluid.
The most abundant cation in the extracellular fluid (ECF) is sodium (Na+). It plays a crucial role in maintaining fluid balance, facilitating nerve signaling, and supporting muscle contraction.
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.
