Understand that the nervous system is composed of various structures that work together to transmit signals throughout the body.
Identify the key components of the nervous system: neurons, synapses, axons, and dendrites.
Recognize that a neuron is the basic building block of the nervous system, responsible for receiving, processing, and transmitting information.
Differentiate between the terms: a synapse is the junction between two neurons, an axon is the long projection of a neuron that conducts electrical impulses away from the neuron's cell body, and dendrites are the branched projections that receive signals from other neurons.
Conclude that the neuron is the smallest structural and functional unit of the nervous system, as it is the primary cell responsible for communication within the system.
