1. Which part of the neuron is responsible for receiving signals from other neurons?
Axon
Dendrite
Cell body
Myelin sheath
2. What is the primary function of the myelin sheath?

To provide structural support
To insulate the axon and speed up signal transmission
To generate electrical impulses
1. The is the long, slender projection of a nerve cell that conducts electrical impulses away from the cell body.
2. Gaps in the myelin sheath along the axon are called the .
