Which two systems work together to control movement in the body?

The muscular and nervous systems collaborate closely to control movement in the body. The nervous system is responsible for sending signals from the brain to the muscles, instructing them when to contract and relax. This signaling is crucial for initiating and coordinating voluntary movements, such as walking or typing, as well as involuntary movements, like reflexes. The muscle fibers respond to these signals, contracting to produce motion.

In addition, the nervous system continuously monitors the body's position and movement, providing feedback to ensure movements are smooth and controlled. Without this partnership, effective movement would not be possible, as the muscles require precise instructions from the nervous system to function correctly.
