The cells that carry messages to and from different parts of the body are called neurons.

Here's why:

* Neurons are specialized cells designed for communication. They have unique structures like dendrites (receive signals) and axons (transmit signals) that allow them to transmit electrical and chemical signals efficiently.

* The nervous system is built on neurons. This network of neurons enables your brain to receive information from your senses, process it, and send commands to your muscles and organs.
