Which system conducts movement of electrical impulses along neurons and across synaptic gaps to control movement and thought?

Signals in this system travel as electrical impulses along neurons and cross gaps between them at synapses to coordinate movement and thought. Neurons transmit action potentials rapidly from one cell to the next, and at synapses they release neurotransmitters that carry the signal to the next neuron or to muscles, enabling precise control of actions and processing of information in the brain and spinal cord. The digestive system handles nutrient processing, not rapid signal transmission. The muscular system carries out movement but relies on signals from the nervous system rather than conducting impulses itself. The endocrine system uses hormones traveling through the bloodstream, producing slower, longer-lasting effects rather than the fast, point-to-point communication seen with neural signaling. This combination of fast electrical signaling along neurons and chemical signaling across synapses is why the nervous system is responsible for movement and thought.
