Which option is not listed as a primary muscle function?

Muscle actions are about how the tissue itself works: it contracts to create movement, helps hold joints steady to keep balance and posture, and can store energy substrates like glycogen and fats for later use. Nerve conduction isn’t a muscle function—it’s a process of the nervous system that carries signals to muscles to trigger contraction. The muscle’s job isn’t to conduct nerves; it responds to those nerve signals to move or stabilize. That’s why nerve conduction is not considered a primary muscle function, making it the correct choice. Movement and stabilization fit as clear muscle roles, and substance storage aligns with the muscle’s ability to store energy sources.
