Sodium is the primary cation for ECF, potassium is the primary cation for ICF.
Calcium
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.
The chief intracellular cation is potassium (K+). It plays a vital role in maintaining cell function, including membrane potential and cellular signaling. Potassium is involved in various cellular processes such as muscle contraction and nerve transmission.
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 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.
