DENDRITIC TRANSPORT Meaning and
Definition
-
Dendritic transport refers to the process by which various cellular materials are transported within the dendrites of a neuron, a type of nerve cell in the nervous system. Dendrites are the branch-like extensions of a neuron that receive incoming signals from other neurons.
In the context of dendrites, transport involves the movement of molecules, organelles, and other cellular components along the dendritic shaft, as well as their distribution within different regions of the dendritic tree. This transportation process is crucial for maintaining the integrity and functionality of dendrites, as well as for facilitating effective communication between neurons.
Dendritic transport can occur in two main directions: anterograde and retrograde. Anterograde transport refers to the movement of cargo from the cell body towards the dendrite's periphery, while retrograde transport involves the transportation of materials from the dendritic periphery back towards the cell body.
This essential cellular process is facilitated by molecular motors, such as kinesins and dyneins, which move along the microtubules present within the dendrites. These motors utilize adenosine triphosphate (ATP) as an energy source to carry out the transportation of materials.
Dendritic transport plays a pivotal role in various neurobiological processes, including the development of neuronal circuits, synaptic plasticity, and the maintenance of dendritic structure and function. It allows for the delivery of essential molecules, such as proteins and RNA, to the appropriate dendritic compartments, where they can influence synaptic activity and neuronal function. Dysregulation of dendritic transport has been implicated in several neurological disorders, highlighting its importance in normal brain function.

Etymology of DENDRITIC TRANSPORT
The word "dendritic" in "dendritic transport" originates from the Greek word "dendron", which means "tree". It refers to the branching structure of dendrites, which are the specialized extensions of nerve cells (neurons) that receive and transmit electrical signals.
On the other hand, the term "transport" comes from the Latin word "transportare", which means "to carry across". In this context, it refers to the movement or transportation of molecules, organelles, or substances within the complex network of dendrites to facilitate neuronal communication and various cellular functions.
So, when combined, "dendritic transport" reflects the process of carrying or transferring materials within the dendritic arborization of neurons.
