1

Which of the following embryonic brain vesicles forms the cerebrum?

telencephalon

2

Which of the following is NOT part of the brain stem?
mesencephalon **
medulla oblongata
pons
thalamus

The thalamus is part of the diencephalon, not part of the brain stem.

3

Which of the meninges is adhered to the surface of the brain and accompanies the branches of the blood vessels as they penetrate the surface of the brain?

pia mater

4

Which of the following is NOT a function of cerebrospinal fluid?
-supporting the brain
-transporting nutrients, chemical messengers, and waste products
-cushioning the brain
-providing the blood–brain barrier

providing the blood–brain barrier

5

Which of the following is NOT a function of the medulla oblongata?
-receiving and interpreting visual stimuli -regulating heart rate and force of contraction
-linking the brain with the spinal cord
-setting the basic rate for respiratory movements

-receiving and interpreting visual stimuli

6

Which of the following is NOT a set of regions linked by the pons?
-right and left cerebral hemispheres
-cerebellum to cerebrum
-cerebellum to brain stem
-nuclei of the pons to the cerebellar hemisphere of the opposite side

The corpus callosum links the right and left cerebral hemispheres; they are not linked by the pons.

7

White matter in the cerebellum is called the ________________ because it resembles a tree.

arbor vitae

8

Which of the following is a function of the cerebellum?

fine-tuning muscle movements

9

The corpora quadrigemina process __________.

visual and auditory sensations

10

What is the function of the thalamus?

to filter and pass sensory information to the basal nuclei and cerebral cortex

11

Which of the following is NOT a function of the hypothalamus?

12

Which produces the hormone melatonin?

The pineal gland produces the hormone melatonin.

13

The limbic system is responsible for __________.

The limbic system is responsible for establishing emotional states.

14

Which cerebral lobe is the most anterior?

frontal

15

What is a function of the basal nuclei?

muscle tone and learned movement patterns

16

What region of the cerebral cortex receives sensory information from the taste receptors of the tongue and pharynx?

The gustatory cortex receives information from the taste receptors of the tongue and pharynx.

17

What directs voluntary movements by initiating impulses in somatic motor neurons?

primary motor cortex

18

Which cranial nerve contains sensory fibers coming from the inner ear and is responsible for hearing and balance?

The vestibulocochlear nerve contains sensory fibers coming from the inner ear and is responsible for hears and balance.

19

Which of the cranial nerves has five branches and controls the lacrimal and salivary glands and muscles of the face?

facial nerve

20

Which of the following is a visceral cranial reflex?
-direct light reflex
-corneal reflex
-tympanic reflex
-auditory reflex

direct light reflex
