Here's how it works:
* Movement: The brain sends signals to the muscles, telling them to contract and relax in specific sequences to create movement.
* Breathing: The brain controls the respiratory muscles, like the diaphragm and intercostal muscles, to regulate the intake and expulsion of air.
* Eating: The brain sends signals to the muscles of the mouth, throat, and stomach to help chew, swallow, and digest food. It also controls the release of digestive juices and hormones.
While the brain is the central command center, it relies on the spinal cord to relay these signals to the rest of the body.
