Which type of axon transmits a nerve impulse at the highest rate?

• Large nonmyelinated

• Large myelinated

• Small nonmyelinated

• Small myelinated

Which nerves are capable of regeneration?

• Nerves within the brain and spinal cord

• . Peripheral nerves that are cut or severed

• Myelinated nerves in the peripheral nervous system

• Unmyelinated nerves of the peripheral nervous system

The neurotransmitter, norepinephrine, is secreted in the:

• Somatic nervous system

• Parasympathetic preganglion

• Sympathetic postganglion

• Parasympathetic postganglion

Both oligodendroglia and Schwann cells share the ability to:

• Form a myelin sheath

• Remove cellular debris

• Transport nutrients

• Line the ventricles

During a synapse, what change occurs after the neurotransmitter binds to the receptor?

• The permeability of the presynaptic neuron changes; consequently, its membrane

  potential is changed as well.

• The permeability of the postsynaptic neuron changes; consequently, its membrane

  potential is changed as well.

• The postsynaptic cell prevents any change in permeability and destroys the action

  potential.

• The presynaptic cell synthesizes and secretes additional neurotransmitters.

What name is given to a large network of neurons within the brainstem that is essential for

maintaining wakefulness?

• Midbrain

• Reticular activating system

• Medulla oblongata

• Pons

Thought and goal-oriented behaviors are functions of which area of the brain?

• Cerebellum

• Limbic system

• Prefrontal lobe

• . Occipital lobe

The region responsible for the motor aspects of speech is located in the:

• Wernicke area in the temporal lobe

• Broca area in the frontal lobe

• Wronka area in the parietal lobe

• Barlow area in the occipital lobe

Parkinson and Huntington diseases are associated with defects in which area of the brain?

• Thalamus

• Medulla oblongata

• Cerebellum

• Basal ganglia
