True. When you smell something, sensory information is transmitted from the olfactory receptors in the nose to the brain via afferent neurons. These neurons carry the sensory signals toward the central nervous system, where the brain processes the information related to the smell.
Neurons are functionally classified based on their structure, neurotransmitter type, and the direction of signal transmission. Structural classifications include multipolar, bipolar, and unipolar neurons, while neurotransmitter types can be excitatory or inhibitory. Direction of signal transmission can be sensory (afferent), motor (efferent), or interneurons.
The message that travels through a neuron is an electrical impulse called an action potential. It is generated when the neuron is stimulated and travels along the neuron's axon, facilitated by the movement of charged ions. This ultimately allows the neuron to communicate with other neurons or target cells.
The message travels through the axon and Schwann cells (which make up the axon) as an electrical message. When it reaches the dendrite, it is converted into a chemical message where it can be picked up by another neuron.
The neuron is the functional portion of the central nervous system, carrying impulses to the designated location. Neurons also have the role of interpreting an impulse, and waiting for a response. Neurons fall under the category of sensory neurons, interneurons and motor neurons.
Neurons send messages in the form of electrical signals called action potentials. When a neuron is stimulated, it generates an action potential that travels along its axon to communicate with other neurons or target cells. This electrical signal can trigger the release of neurotransmitters, which are chemical signals that transmit the message across the synapse to the next neuron.

Simple reflexes are controlled by the spinal cord. The message travels from the sense receptors near the skin through the afferent nerve fibers to the spinal cord. In the spinal cord, the messages are relayed through association neurons to the efferent nerve fibers, which carry them to the muscle cells that cause the reflex movement.

The electrical message that travels along a neuron is called an action potential. It is a brief change in electrical voltage that travels down the length of the neuron, allowing for communication between neurons and the transmission of signals throughout the nervous system.
It travels in one direction either afferent or efferent.
The message in a neuron starts at the dendrites, which are the branch-like extensions that receive signals from other neurons. When these signals are strong enough to reach a certain threshold, they trigger an action potential that travels down the axon. This electrical impulse then propagates to the axon terminals, where it can communicate with other neurons or target cells.
Efferent nerves carry signals away from the brain to muscles and glands, enabling movement and other bodily functions. A nerve impulse travels in one direction along these nerves, from the central nervous system to the periphery.

What they relay is whether of not they were 'on' or 'off' and how often; and this occurs as an action potential firing frequency. There is no message in the sense that neurons might pass on complex messages, like an email for instance; or store memories of events and facts. No one neuron can do anything like that. It takes many neurons working together to achieve this.
