Axonal transport

Axonal Transport

Axonal transport is a cellular process responsible for the movement of mitochondria, lipids, synaptic vesicles, proteins, and other cellular materials such as organelles from the neuron's cell body through the axon to the synapse. This process is essential for the proper functioning and survival of neurons.

Pronunciation

Axonal transport: /ækˈsoʊnəl ˈtrænspɔːrt/

Etymology

The term "axonal transport" is derived from the word "axon", which comes from the Greek word 'ἄξων' (áxōn, "axis") and "transport", which originates from the Latin word 'transportare' meaning "to carry across".

Types of Axonal Transport

Axonal transport can be classified into two main types: Anterograde transport and Retrograde transport.

Anterograde transport involves the movement of materials from the cell body towards the synapse. This process is facilitated by a protein known as kinesin.

Retrograde transport involves the movement of materials from the synapse back to the cell body. This process is facilitated by a protein known as dynein.
