Usually by size and the type of neurotransmistter it produces. Electrophysiologists also classify neurons by their firing rates
This is an addition to the above-mentioned answer. To be more specific, we can classify neurons based on their structural or functional properties.
1) Structural classification :
- based on polarity = unipolar + pseudounipolar + bipolar, + multipolar (Golgi 1, Golgi 2)
- based on their unique features (distinct shapes and locations) = basket cells + betz cells + medium spiny neurons + purkinje cells + pyramidal cells + Renshaw cells + granule cells + anterior horn cells
2) Functional classification :
- based on directions = afferent + efferent + interneurons
- based on their actions on other neurons = excitatory (they increase firing rate) + inhibitory(they decrease firing rate) + modulatory (doesn't really related to firing rate, but they cause long-lasting effects)
- based on their discharging patterns = tonic or regular spiking + phasic or bursting + fast spiking
- based on neurotransmitters they produced = cholinergic + GABAergic + glutamatergic + dopaminergic + serotonergic

On the basis of structural classification which joint is fibrous connective tissue?
A fibrous joint is a structural classification where bones are joined by fibrous connective tissue. Examples of fibrous joints include sutures in the skull and syndesmoses in the distal tibiofibular joint.
Why is the synapse not a structural feature of a neuron?
The synapse is the functional junction between two neurons where communication occurs, but it is not a part of the neuron's physical structure. Neurons are the individual cells that make up the nervous system and consist of a cell body, dendrites, and an axon. The synapse is the space between neurons where neurotransmitters are released to signal information transfer.
What is the functional unit of the nervous system?
The nervous system gathers information from the external environment, stores and processes it, and initiates the appropriate responses.__________________________________excuse me, i think he / she wasn't asking about what the nervous system is but what isThe functional unit of the nervous system is the neuron.
Processes that carry impulses to another neuron?
These processes are called axons. Axons are long, slender projections of a neuron that conduct electrical impulses away from the neuron's cell body to transmit information to other neurons, muscles, or glands.
What neuron is before a synapse?
The synapse consists of the two neurons, one of which is sending information to the other. The sending neuron is known as the pre-synaptic neuron (i.e. before the synapse) while the receiving neuron is known as the post-synaptic neuron (i.e. after the synapse).
