Accepted Answer

Broca’s area

Question 3

Which sequence correctly traces the flow of cerebrospinal fluid (CSF) from its production to reabsorption?

Accepted Answer

Lateral ventricles → third ventricle → cerebral aqueduct → fourth ventricle → subarachnoid space → arachnoid villi

Question 4

Which of the following is a function of the cerebellum?

Accepted Answer

Planning and practicing learned movement patterns

Question 5

Damage to which structure would most likely result in loss of conscious awareness and alertness?

Accepted Answer

Reticular Activating System (RAS)

Question 6

Which of the following statements about the cranial meninges is correct?

Accepted Answer

The pia mater is the innermost layer and is bound to the brain surface by astrocytes.

Question 7

A lesion in the left occipital lobe would most likely affect which function?

Accepted Answer

Visual processing

Question 8

Which of the following best describes the role of the thalamus?

Accepted Answer

It relays sensory information to the appropriate sensory cortices, except for olfactory sensations.

Question 9

Which of the following tracts connects the left and right cerebral hemispheres?

Accepted Answer

Commissural tracts

Question 10

A patient with a tumor compressing the cerebral aqueduct would most likely develop which condition?

Accepted Answer

Hydrocephalus due to impaired CSF flow

Question 11

Which of the following is a function of the limbic system?

Accepted Answer

Processing of emotions and memory formation

Question 12

Which nuclei in the hypothalamus are responsible for producing antidiuretic hormone (ADH)?

Accepted Answer

Supraoptic nuclei

Question 13

Which of the following best describes the function of the basal nuclei?

Accepted Answer

They are involved in planning, coordinating, and organizing movements by containing both stimulatory and inhibitory nuclei.

Question 14

Which brain region is primarily responsible for maintaining homeostasis and regulating the endocrine system?

Accepted Answer

Hypothalamus

Question 15

Which of the following is NOT a function of cerebrospinal fluid (CSF)?

Accepted Answer

Initiation of voluntary muscle contraction

Question 16

Which structure is responsible for relaying proprioceptive information to the cerebellum?

Accepted Answer

Inferior olivary nuclei

Question 17

A patient with damage to the right representational hemisphere would most likely have difficulty with which of the following?

Accepted Answer

Understanding spatial relationships

Question 18

Which of the following best describes the function of the prefrontal cortex?

Accepted Answer

It determines most of your personality and is involved in complex decision-making.

Question 19

Which of the following is true regarding the organization of gray and white matter in the cerebrum?

Accepted Answer

Question 20

Which of the following best explains why a blow to the side of the head can cause a subdural hematoma?
