Which organ sends messages to muscles to carry out voluntary actions like writing or moving a chair?
Brain
Voluntary actions are those carried out consciously, such as writing, walking or moving a chair. These actions are controlled and coordinated by the cerebrum of the brain, which sends nerve impulses through motor neurons to the skeletal muscles, telling them exactly when and how to contract.
The heart pumps blood, the stomach digests food and the lungs handle gas exchange — none of them initiate messages to muscles for voluntary movement. Only the brain acts as the command centre for such actions.
Hence, the answer is Brain.
