Ch 8 Nervous system

A neuron consists of:

• a cell body

• dendrites

• both A and B

• both A and B and one axon

The part of a neuron that carries impulses toward the cell body is the:

• dendrite

• axon

• cell body

• myelin sheath

The part of a neuron that contains the nucleus is the:

• dendrite

• axon

• cell body

• myelin sheath

The part of a neuron that carries impulses away from the cell body is the:

• dendrite

• axon

• cell body

• myelin sheath

The part of peripheral nerve tissue that forms the myelin sheath is the:

• oligodendrocyte

• axon

• Schwann Cell nucleus

• Schwann cell membrane

Which type of neuroglia phagocytizes pathogens?

• astrocytes

• oligodendrocytes

• Schwann cells

• microglia

Which type of neuroglia helps form the blood–brain barrier?

• astrocytes

• oligodendrocytes

• Schwann cells

• microglia

Which type of neuroglia forms the myelin sheath?

• astrocytes

• oligodendrocytes

• Schwann cells

• microglia

Sensory neurons carry impulses from:

• CNS to effectors

• effectors to CNS

• CNS to receptors

• receptors to CNS

Motor neurons carry impulses from:

• CNS to effectors

• effectors to CNS

• CNS to receptors

• receptors to CNS
