Nerves and Synapses

How does the nervous system help you learn new information, such as studying for a test?

• By releasing hormones

• By digesting food faster

• By creating new muscles

• By forming connections between neurons

When you feel pain from an injury, which sequence correctly describes the pathway of signals?

• Sensory neuron → Brain → Motor neuron

• Sensory neuron → Spinal cord → Brain

• Brain → Sensory neuron → Motor neuron

• Motor neuron → Spinal cord → Sensory neuron
