Galvani\'s experimet tells us that nerves carry messages to the muscle through electrical impulses.
nerves
motor nerves are the one responsible sending messages to the brain..
your brain sends messages to your nerves
nerves send the messages that make muscles move
nerves send the messages that make muscles move
Nerves carry messages to the muscles to react. Nerves help us feel pain, heat, and cold.
Muscles receive instructions to move from the brain.
You are probably thinking of motor nerves. Those are the nerves which transmit messages from the brain to the muscles, causing movement. The other kind of nerves are sensory, which transmit sense perceptions.
Messages are transmitted from your spinal cord to muscles in your hands through motor neurons. These motor neurons carry signals from the spinal cord to the muscles, causing them to contract and perform the desired movement. The process involves electrical impulses traveling along the motor neurons to trigger muscle movement.
1 sensory organ - sensory nerves - spinal cord - brain 2 brain - motor nerves - spinal cord - muscles
There are no muscles that are controlled by force of will. Your brain sends messages to the nerves that control your muscles and that is what moves them.
Nerves relay messages by transmitting an electrical impulse.
