What are the two major types of nerve cells?

• Dendrites and axons

• Sensory and motor neurons

• Astrocytes and microglia

• Neurons and neuroglia

What is the main function of neuroglia?

• To send impulses away from the cell body

• To bring impulses towards the cell body

• To support, insulate, and protect neurons

• To conduct impulses around the body

What is the structure that wraps around the axon and helps the nerve impulses to travel more quickly?

• Neurilemma

• Astrocyte

• Axon terminal

• Myelin sheath

Which type of neuron carries impulses toward the CNS?

• Afferent neuron

• Efferent neuron

• Interneuron

• Multipolar neuron

What is the function of the myelin sheath?

• To secrete and circulate cerebrospinal fluid

• To protect the neuron from damage

• To provide support and anchor neurons

• To help the nerve impulses travel more quickly
