Dendron vs. Dendrite — What's the Difference?
By Urooj Arif & Fiza Rafique — Updated on April 3, 2024
Dendron refers to the entire tree-like extension from a neuron, including its branches, while a dendrite is a specific branch of a dendron that receives signals from other neurons.

Key Differences
Dendrons serve as the neuron's receptive region, playing a critical role in integrating synaptic inputs and determining the neuron's response to stimuli. They can vary greatly in shape and size among different neuron types, which affects the neuron's connectivity and function. Dendrites, being components of dendrons, contribute to the complexity of synaptic integration by increasing the surface area available for synapses. This differentiation is crucial for understanding the hierarchical organization of neuronal structures and their role in neural processing.
The morphology of dendrites, such as their thickness, length, and the pattern of branching, directly influences the synaptic plasticity and the strength of neural connections. Dendrons, encompassing all dendritic branches, collectively determine the neuron's overall capacity to connect with and respond to other neurons. This distinction highlights the importance of structural variation within the nervous system in facilitating diverse neural functions.
Dendritic spines, small protrusions found on dendrites, are sites of synaptic contact with axons and are key to synaptic transmission and plasticity. While dendritic spines are features of dendrites, the concept of dendrons encapsulates the broader structural and functional context in which these spines operate, emphasizing the integrated nature of neural signaling pathways.
The distinction between dendrons and dendrites underscores the complexity of neural architecture and its functional implications. Understanding this differentiation provides insight into the mechanisms of neural communication and the structural basis of the nervous system's ability to process and transmit information.

Dendrite
Dendrites (from Greek δένδρον déndron, "tree"), also dendrons, are branched protoplasmic extensions of a nerve cell that propagate the electrochemical stimulation received from other neural cells to the cell body, or soma, of the neuron from which the dendrites project. Electrical stimulation is transmitted onto dendrites by upstream neurons (usually via their axons) via synapses which are located at various points throughout the dendritic tree.
