Neuron Structure

Spaces between pieces of myelin are called

• nodes of Ranvier

• astrocytes

• Schwann cells

• empty spots

The electrically-active cell in nervous tissue

• neuron

• astrocyte

• oligodendrocyte

• satellite cell

Neurons are very metabolically active. Therefore, they contain large numbers of _____ per cell.

• mitochondria

• nuclei

• myofibrils

• axons

The function of myelin is to

• keep sodium ions in the axon

• speed up the axon potential

• maintain the neuron's shape

• keep axons warm
