Summary Introduction

To describe:

The type of nerve fiber in which the conduction of an action potential is most energy-efficient.

Introduction:

The action potential is passed from a neuron to another cell or neuron through signaling molecules. Synapse is a region where a neuron transmits chemical signals to another cell. The neuromuscular junction is a synapse between a neuron and a muscle cell. The action potential travels along the axon of the neuron to the axon terminal. The terminals of axon contain vesicles filled with neurotransmitter. The neurotransmitters relay signals between cells at a synapse.
