_____ are single fibers that carry messages to other neurons.

A) Dendrites
B) Axons
C) Terminal buttons

Axons

Long, slender projections of nerve cells that transmit electrical impulses away from the neuron's cell body to other neurons or to muscles or glands.

Dendrites

Dendritic processes of a neuron that capture signals from other neurons.

Terminal Buttons

Terminal buttons are small knobs at the end of an axon that release neurotransmitters, facilitating the transfer of nerve impulses from one neuron to another.
