What is the main function of afferent nerves?

• Send impulses towards the CNS

• Send impulses away from the CNS

• Control voluntary muscle movement

• Maintain cerebrospinal fluid

Which part of the nervous system is responsible for involuntary muscle control?

• Somatic Nervous System

• Autonomic Nervous System

• Central Nervous System

• Peripheral Nervous System

What is the role of astrocytes in the nervous system?

• Fight infections in the CNS

• Wrap around capillaries

• Maintain cerebrospinal fluid

• Send impulses towards the CNS

Which type of neuroglia is responsible for maintaining cerebrospinal fluid?

• Microglia

• Astrocytes

• Ependymal Cells

• Afferent nerves

Which type of neuroglia makes up the myelin sheath?

• Schwann cells

• Satellite cells

• Oligodendrocytes

• Dendrites

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

• Support neuron cell bodies

• Produce myelin sheaths
