Fairytale twin mage brothers Sodium and Potassium standing side by side, both channeling flows of electric energy within the body. Sodium is a mage dressed in bright blue and silver robes; Potassium is a mage in purple-green robes. Between them flow opposite-directed glowing energy streams resembling the movement of ions across a cell membrane. Around the characters are glowing nerve fibers, electric impulses, and contracting muscle fibers.
In the center of the image is a large glowing magical bubble divided into two halves: a blue half with the large label «Na» and a purple-green half with the large label «K».
At the bottom, a short scientifically accurate caption in Russian: «Na⁺ и K⁺ участвуют в проведении нервного импульса и регулируют сердечный ритм»
Visually emphasize the interaction and cooperation between sodium and potassium, not as independent elements. Colorful modern fantasy illustration for 10–11 grade students, premium biology textbook style, magical fairytale academy, bright magical energy, clean light background, high detail, vertical format, unified style of a chemical elements series, no extra text.
