Question

Where can you find nodes of Ranvier?

• A. on an axon
• B. in the cell body
• C. on a dendrite
• D. both a and c

Answer 1

The correct option is A on an axon

A neuron has three main parts dendrites, an axon, and a cell body or soma. Some neurons are myelinated that is the axon of the neuron is covered by a myelin sheath. Nodes of Ranvier are microscopic gaps found within myelinated axons. Their function is to speed up propagation of action potentials along the axon.
