What is the functional unit of the nervous system?

Explanation:
The basic signaling cell, a neuron, is the unit that carries out nervous system signaling. Neurons are specialized to receive inputs through dendrites, integrate that information in the cell body, and transmit signals along the axon to other neurons, muscles, or glands at synapses. This combination of receiving, processing, and sending signals is what makes a neuron the fundamental working unit of the nervous system. The other structures play important roles but aren’t the basic signaling unit. A synapse is the junction where communication occurs between neurons, a brain is a complex organ made up of many neurons and supporting cells, and a nerve is a bundle of nerve fibers outside the central nervous system.
