The neuron processes that convey messages away from the cell body are called axons.

Here's a breakdown:

* Axons: These are long, slender projections that transmit electrical signals (action potentials) from the cell body to other neurons, muscles, or glands. They are typically covered in a myelin sheath, which acts as an insulator and speeds up signal transmission.

* Dendrites: These are branched extensions that receive signals from other neurons and transmit them towards the cell body.

So, while dendrites receive signals, axons are responsible for sending them out.
