Which part of the nervous system conducts signals to and from the brain?

• Spinal cord

• Astrocytes

• Schwann cells

• Microglia

What is the function of efferent nerves?

• Tell the body how it is being affected by stimuli

• Stimulate muscles to produce effort

• Absorb and dispose of dead cells and bacteria

• Wrap around nerve fibers and produce myelin

• Astrocytes

• Microglia

• Ependymal cells

• Oligodendrocytes

What is the function of Schwann cells in the peripheral nervous system?

• Form fatty myelin sheaths around nerve fibers

• Serve as cushioning support cells

• Link nutrient-supplying capillaries to neurons

• Absorb and dispose of dead cells and bacteria

Which part of a neuron carries impulses away from the soma to the axon terminals?

• Dendrites

• Myelin sheath

• Axon

• Axon terminals

What is the function of the myelin sheath?

• Absorb and dispose of dead cells and bacteria
