Final answer:
The nervous system in Biology sends action potentials from the periphery to the brain. These action potentials are generated by the controlled distribution of ions across the neuron membrane, allowing the electrical signal to travel along the axon and pass through synapses.
Step-by-step explanation:
The subject of this question is Biology. The nervous system is responsible for sending signals in the form of action potentials from the periphery to integrating centers such as the brain. These action potentials are generated by the controlled distribution of ions across the membrane of neurons, which creates an electrical signal. This signal travels along the axon of the neuron and is passed from one neuron to another through synapses in the spinal cord and brain.
