Which of the following is NOT a function of muscles?

The correct choice highlights that the storage of minerals is not a primary function of muscles. Muscles primarily serve several essential functions linked to movement and physiology.

Muscles are involved in the movement of the whole body, facilitating activities ranging from walking to running, and they also play a crucial role in the control of openings and passageways, such as those found in the digestive and urinary systems. Additionally, muscles contribute significantly to body heat production through thermogenesis during muscle contractions. This heat is essential for maintaining the body’s temperature, especially during physical activity.

In contrast, while certain tissues in the body, like bones, are responsible for the storage of minerals such as calcium and phosphorus, muscle tissues do not serve this function. Their primary roles are linked to movement, posture, and heat generation rather than mineral storage. This distinction clarifies why the storage of minerals is not considered a function of muscles.
