Sodium
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.
No; the major extracellular anion is chloride.
The major cation in cytoplasm is potassium (K+). It plays a key role in maintaining cell function and regulating cell volume.
Sodium ion is the most concentrated ion in the extracellular fluid.
The Chief Extracellular cation is sodium.
