Axons:

Quizplus · Accepted Answer

Axons carry an action potential in the direction of a synapse. Axons are the long, thin extensions of a neuron that transmit electrical impulses away from the cell body towards other neurons, muscles or glands. They are specialized to conduct and transmit action potentials, which is the electrical signal that neurons use to communicate with each other. Axons do not form the gray matter of the brain and spinal cord, as this is made up of cell bodies and dendrites. Axons also do not act independently of the cell body, as they are a part of the neuron and require input and energy from the cell body. Axons do not have neurotransmitter receptors, as these are located on the postsynaptic membrane of the neuron. Lastly, axons do not decide whether to transmit an action potential, as this is determined by the input received by the neuron and the threshold necessary to generate an action potential.
