Neuron anatomy

About the anatomy of neurons
  • Neurons are the building blocks of the nervous system.
  • A typical neuron consists of a cell body (soma), dendrites, and a single axon.
  • Dendrites and axons form filamentous extensions of the soma.
  • Dendrites typically branch profusely as they extend from the soma.
  • An axon can be as long as a metre in length.
  • At the farthest tip of the axon’s branches are axon terminals, where the neuron can transmit a signal across a synapse to another cell.
