The optic tracts carry visual information from the retina to the
A) supraoptic nuclei.
B) pulvinar.
C) lateral geniculates.
D) medial geniculates.
E) paraventricular nuclei.

Accepted Answer

The optic tracts carry visual information from the retina to the lateral geniculate nuclei, which are part of the thalamus and play a crucial role in processing visual information before it is relayed to the visual cortex.

Question 8

The________ provides the principal link between the nervous and endocrine systems.
A) cerebellum
B) pons
C) cerebrum
D) medulla oblongata
E) hypothalamus

Accepted Answer

The hypothalamus is responsible for linking the nervous system to the endocrine system via the pituitary gland.

Question 9

Damage to the pyramidal cells of the cerebral cortex would directly affect
A) sight.
B) voluntary motor activity.
C) hearing.
D) perception of pain.
E) both A and C

Accepted Answer

Pyramidal cells in the cerebral cortex are primarily involved in controlling voluntary motor activity.

Question 10

An)__________ is a printed record of the brain's electrical activity over a period of time.
A) CT scan
B) electrocardiogram
C) x- ray
D) MRI
E) electroencephalogram

Accepted Answer

An electroencephalogram (EEG) is a test that detects electrical activity in the brain using small, flat metal discs (electrodes) attached to the scalp.

Question 11

Stimulation of the reticular formation results in
A) coma.
B) increased consciousness.
C) decreased cerebral function.
D) sleep.
E) B, C, and D

Accepted Answer

The reticular formation is a network of neurons in the brainstem that is involved in arousal, attention, and consciousness. Stimulation of the reticular formation can increase consciousness and alertness.

Question 12

Which of the following is a function of the hypothalamus?
A) secretes oxytocin
B) regulates body temperature
C) controls autonomic centers
D) produces ADH
E) all of the above

Accepted Answer

The hypothalamus is involved in all these functions: it regulates body temperature, controls autonomic centers, and is involved in the secretion of hormones like oxytocin and ADH.

Question 13

Bob is struck on the left side of the head and is knocked unconscious. When he recovers consciousness, he can hear individual words but cannot understand the meaning of phrases or sentences. This implies damage to his
A) vestibulocochlear nerve.
B) temporal lobe.
C) speech center.
D) general interpretive area.
E) prefrontal lobe.

Accepted Answer

Damage to the general interpretive area, also known as Wernicke's area, affects the ability to understand the meaning of phrases or sentences, which aligns with Bob's symptoms.

Question 14

Autonomic centers that control blood pressure, heart rate, and digestion are located in the
A) mesencephalon.
B) diencephalon.
C) pons.
D) cerebellum.
E) medulla oblongata.

Accepted Answer

The medulla oblongata contains autonomic centers that regulate vital functions such as blood pressure, heart rate, and digestion.

Question 15

Cerebrospinal fluid enters the blood circulation at the
A) superior sagittal sinus.
B) dural drain.
C) tentorium cerebelli.
D) frontal sinus.
E) jugular veins.

Accepted Answer

Cerebrospinal fluid (CSF) is absorbed into the venous blood circulation through the arachnoid granulations, which protrude into the superior sagittal sinus.

Question 16

Figure 13- 1 The Circulation of Cerebrospinal Fluid
Use Figure 13- 1 to answer the following questions:
-Cerebrospinal fluid
A) is normally produced twice as fast as it is removed.
B) has almost the same composition as blood plasma.
C) is formed by a passive process.
D) is secreted by ependymal cells.
E) both B and D

Accepted Answer

The answer of  Figure 13- 1 The Circulation of...

Question 17

Which of the following is not one of the basal nuclei? A) hippocampus B) amygdaloid body C) caudate nucleus D) globus pallidus E) putamen

Accepted Answer

The hippocampus is not one of the basal nuclei. The basal nuclei are a group of subcortical structures that are involved in motor control and learning. The hippocampus is a part of the limbic system and is involved in memory formation.

Question 18

Excitation of neurons in the basal nuclei would lead to
A) involuntary speech production.
B) increased muscle tone.
C) inability to sense pain.
D) loss of consciousness.
E) sexual arousal.

Accepted Answer

The basal nuclei are involved in the regulation of voluntary motor movements and muscle tone. Excitation of neurons in this area can lead to increased muscle tone.

Question 19

The medulla oblongata relays auditory information to the
A) red nuclei.
B) substantia nigra.
C) inferior colliculi.
D) superior colliculi.
E) cerebral peduncles.

Accepted Answer

The medulla oblongata relays auditory information to the inferior colliculi, which are part of the auditory pathway in the brainstem.

Question 20

Difficulty in swallowing may be a sign of damage to which cranial nerves)?
A) vagus
B) facial
C) glossopharyngeal
D) A, B, and C
E) A and C only

Accepted Answer

The vagus nerve (cranial nerve X) and the glossopharyngeal nerve (cranial nerve IX) are both involved in swallowing. Damage to either of these nerves can cause difficulty swallowing.
