Final answer:

Sodium (Na+) is crucial for maintaining various bodily functions, including cell permeability and nerve impulse transmission. Na+ retention does not cause diuresis, contrary to one of the statements provided.


Explanation:

Sodium (Na+) is the major extracellular cation in the body, playing vital roles in maintaining cell permeability, active transport, muscle contraction, and nerve impulse transmission.

One statement not true about Na+ is that Na+ retention causes diuresis. Diuresis is the process of increased urine production, which is typically associated with sodium excretion, not retention.

Aldosterone, a hormone that affects Na+ concentrations, stimulates Na+ uptake in the kidneys, emphasizing Na+'s importance in the body's electrolyte balance regulation.
