8

Why might damage to the pons be sufficient to cause death?

The pons contains the pneumotaxic and apneustic centers.

9

The cardiovascular centers and the respiratory rhythmicity centers are located in the:

medulla oblongata

10

In the medulla oblongata, the relay stations along sensory or motor pathways consist of the:

nucleus gracilis and nucleus cuneatus

11

The pons links the cerebellum with the:
a. brain stem
b. cerebrum
c. spinal cord

All Three, A, B, and C

12

Excess cerebrospinal fluid is returned to the venous circulation by:

diffusion across the arachnoid villi

13

Coordination and refinement of learned movement patterns at the subconscious level are performed by the:

cerebellum

14

The corpora quadrigemina of the mesencephalon are responsible for processing:

visual and auditory sensations

15

The epithalamus, thalamus, and hypothalamus are anatomical structures of the:

diencephalon

16

Relay and processing centers for sensory information are found in the:

thalamus

17

The sea horse–like structure in the limbic system responsible for storage and retrieval of new long-term memories is the:

hippocampus

18

The functional role of the limbic system serves to identify its role as a:

motivational system

19

Assume that as you are taking this practice exam, you are concentrating and giving it your full attention. If you were connected to an EEG at this moment, what type of brain waves would it record?

beta waves

20

The masses of gray matter that lie within each cerebral hemisphere deep to the floor of the lateral ventricle are the:

cerebral nuclei

21

The neurons in the primary sensory cortex receive somatic sensory information from:

touch, pressure, pain, taste, and temperature receptors

22

The somatic motor association area is responsible for the:

coordination of learned motor responses

23

Which of the following facial nerves does not supply the tongue?

vagus nerves (X)

24

Pyramidal cells are cortical neurons that:

direct voluntary movements

25

A loud noise produces a tympanic reflex that results in:

reduced movement of auditory ossicles

26

The versatility of the brain to respond to stimuli is greater than that of the spinal cord because of:

the number of neurons and complex interconnections between the neurons

27

The mesencephalon, or midbrain, processes:

visual and auditory information and generates involuntary motor responses

28

An individual with a damaged visual association area:

can see letters clearly but cannot recognize or interpret them

29

The three major groups of axons that comprise the central white matter are:

association, commissural, and projection fibers

30

Which of the following statements about the basal nuclei is false?
a. They provide general pattern and rhythm for established movements.
b. They initiate skeletal movements such as walking and stopping.
c. They adjust muscle tone in the appendicular skeleton to set body position during movement.
d. They include the caudate nucleus, lentiform nucleus, globus pallidus, and putamen.

IT IS false - They initiate skeletal movements such as walking and stopping.All the others are true.

31

David hears a strange noise at his back door late one night. It sounds like someone is trying to break into his home. He automatically goes into a "fight or flight" response. What part of the limbic system helps control the flight-or-flight response?

amygdaloid body

32

The mamillary bodies in the floor of the hypothalamus contain motor nuclei that control the reflex movements involved with:

chewing, licking, and swallowing

33

Hypothalamic or thalamic stimulation that depresses reticular formation activity in the brain stem results in:

generalized lethargy or actual sleep

34

The pineal gland, an endocrine structure that secretes the hormone melatonin, is found in the:

epithalamus

35

The pulvinar nuclei of the thalamus integrate:

sensory information for projection to the association areas of the cerebral cortex

36

The part(s) of the diencephalon responsible for coordination of activities of the central nervous system and the endocrine system is (are) the:

hypothalamus

37

The hypothalamus produces and secretes the hormones:

ADH and oxytocin

38

The paraventricular nucleus of the hypothalamus:

secretes oxytocin

39

The nerve fiber bundles on the ventrolateral surfaces of the mesencephalon are the:

cerebral peduncles

40

The effortless serve of a tennis player is a result of establishing:

cerebellar motor patterns

41

Which of the following statements about a subdural hemorrhage is true?

A break in a vein may cause blood to flow to the meningeal layer of the dura mater and down to the arachnoid layer.

42

The centers in the pons that modify the activity of the respiratory rhythmicity center in the medulla oblongata are the:

apneustic and pneumotaxic centers

43

A buildup of CSF in the cranial cavity can lead to:
a. enlargement of the cranium in infants.
b. "water on the brain" or hydrocephaly.
c. compression of brain tissue and impairment of neural function.

All three are correct. A,B, and C
