Question 2

A patient suffers a stroke that damages the left primary motor cortex. Which of the following symptoms would most likely be observed?

Accepted Answer

Loss of voluntary movement on the right side of the body.

Question 3

Which structure connects the left and right cerebral hemispheres, allowing communication between them?

Accepted Answer

Corpus callosum

Question 4

Damage to which area of the brain would most likely result in problems with speech production (motor speech)?

Accepted Answer

Broca’s area

Question 5

Which of the following is a function of the hypothalamus?

Accepted Answer

Regulation of body temperature, water balance, and metabolism

Question 6

A lesion in the cerebellum would most likely result in which of the following symptoms?

Accepted Answer

Loss of balance and coordination

Question 7

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

Accepted Answer

They regulate voluntary motor activities by modifying instructions sent to skeletal muscles by the primary motor cortex.

Question 8

Which lobe of the cerebral cortex is primarily responsible for processing visual information?

Accepted Answer

Occipital lobe

Question 9

Which brain region is responsible for the precise timing of skeletal muscle activity and coordination of body movements?

Accepted Answer

Cerebellum

Question 10

A patient presents with an inability to regulate heart rate and blood pressure. Which brain structure is most likely affected?

Accepted Answer

Medulla oblongata

Question 11

Which of the following statements about the cerebral cortex is correct?

Accepted Answer

It is the outer layer of gray matter responsible for conscious thought and voluntary movement.

Question 12

Which of the following best describes the function of the pons?

Accepted Answer

It contains nuclei involved in the control of breathing.

Question 13

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

Accepted Answer

Initiating voluntary muscle movement

Question 14

Which of the following fiber tracts connects areas within the same cerebral hemisphere?

Accepted Answer

Association fibers

Question 15

A patient is unable to smell after a head injury. Which brain region is most likely damaged?

Accepted Answer

Olfactory area of the temporal lobe

Question 16

Which of the following is a function of the epithalamus?

Accepted Answer

It houses the pineal gland and forms cerebrospinal fluid via the choroid plexus.

Question 17

Which of the following best describes the function of the primary somatic sensory cortex?

Accepted Answer

It receives impulses from the body’s sensory receptors for pain, temperature, and light touch.

Question 18

Which of the following structures is responsible for visual and auditory reflexes?

Accepted Answer

Corpora quadrigemina

Question 19

Which of the following best describes the arrangement of gray and white matter in the cerebellum?

Accepted Answer

Question 20

Which of the following is true regarding the sensory and motor homunculi?

Accepted Answer
