Question: 1 / 400

What is the primary way muscles receive their nourishment?

From nerve signals

From blood vessels

The primary way muscles receive their nourishment is through blood vessels. Blood vessels are responsible for transporting oxygen, nutrients, and essential substances required for muscle function and recovery. This nutrient supply is crucial, especially during physical activities, as muscles demand increased energy and resources to sustain performance.

While nerve signals play an important role in controlling muscle contractions and movements, they do not provide nourishment. Physical activity is essential for muscle health and function, as it helps with the delivery of nutrients and encourages blood flow but is not a direct source of nourishment itself. Fat deposits can serve as a source of energy during prolonged exertion, but they are not a primary means of nourishing muscle tissues in the same way that oxygen and nutrients delivered via blood vessels are.
