Which of the following are paired correctly?

• CNS-brain and spinal cord; PNS-cranial and spinal nerves

• PNS-brain and spinal cord; CNS-cranial and spinal nerves

• Autonomic--brain and spinal cord; Somatic--cranial and spinal nerves

• Autonomic-cranial and spinal nerves; Somatic-brain and spinal cord

What are the two major functional subdivisions of the nervous system?

• Somatic (involuntary) and autonomic (voluntary)

• Somatic (voluntary) and autonomic (involuntary)

• Sensory and motor

• Sympathetic and parasympathetic

Which of the following correctly describes the subdivisions of the autonomic nervous system?

• Somatic and automatic

• Motor and sensory

• Sympathetic and Parasympathetic

• Neuroglia and neurons

Which of the following does NOT describe an astrocyte?

• Star-shaped

• Found in the CNS

• Produce myelin

• Support neurons and blood capillaries

This cell is found in the CNS, is spider-like in appearance, and is phagocytic.

• Oligodendrocyte cell

• Astrocyte cell

• Ependymal cell

• Microglia cell

Which of the following does NOT describe ependymal cells?

• Found in the cavities of the brain and spinal cord

• Produces myelin

• Has cilia

• Circulates cerebrospinal fluid throughout the CNS

This glial cell is found in the CNS and produces myelin sheaths.

• Oligodendrocyte

• Astrocyte

• Ependymal cell

• Microglial cell

A Schwann cell is

• found in the CNS and produces myelin.

• found in the PNS and produces myelin.

• found in the PNS and surrounds the cell body of a neuron.

• found in the CNS and surrounds the cell body of a neuron.

This cell is found in the PNS and serves to protect and cushion the cell body of the neuron.

• Astrocyte

• Ependymal cell

• Mitochondria

• Satellite cell
