Question 4

Which lobe is situated posteriorly in each cerebral hemisphere?
A) occipital
B) parietal
C) temporal

Accepted Answer

The occipital lobe is located at the back (posterior) part of each cerebral hemisphere and is primarily responsible for visual processing.

Question 5

The primary motor cortex of the right cerebral hemisphere:
A) integrates senses from multiple different sources.
B) receives and processes sensory input.
C) controls the motor activity on the right side of the body.
D) controls the motor activity on the left side of the body.

Accepted Answer

The primary motor cortex of the right cerebral hemisphere controls voluntary movements on the left side of the body due to the brain's contralateral control.

Question 6

What information is received by the primary vestibular cortex?
A) vision
B) taste
C) hearing
D) equilibrium

Accepted Answer

The primary vestibular cortex receives information related to equilibrium, which is the sense of balance and spatial orientation.

Question 7

What is NOT part of the cerebrum?
A) frontal lobe
B) brainstem
C) insula
D) parietal lobe

Accepted Answer

The answer of What is NOT part of the cerebrum?
A)...

Question 8

Where are color, object movement, and depth processed?
A) premotor cortex
B) auditory association cortex
C) precentral gyrus
D) visual association areas

Accepted Answer

Color, object movement, and depth are processed in the visual association areas of the brain, which are responsible for interpreting visual information received from the primary visual cortex.

Question 9

Bundles of white matter in the cerebrum are known as:
A) nerves.
B) ganglia.
C) tracts.
D) nuclei.

Accepted Answer

Tracts are bundles of white matter in the central nervous system, including the cerebrum.

Question 10

What results when the corpus callosum is cut?
A) communication between a cerebral cortex in one hemisphere with other areas of the same hemisphere would be impaired
B) communication within a single brain hemisphere would be impaired
C) communication between the brain and spinal cord would be impaired
D) communication between the right and left cerebral hemispheres would be impaired

Accepted Answer

The corpus callosum is a bundle of nerve fibers that connects the left and right cerebral hemispheres, facilitating communication between them. Cutting it disrupts this interhemispheric communication.

Question 11

Select the letter that represents the location of the primary motor cortex. 
A) A
B) B
C) C
D) D

Accepted Answer

The answer of Select the letter that represents the location...

Question 12

The brainstem connects the brain and the:
A) eyes.
B) cerebellum.
C) spinal cord.
D) ventricles.

Accepted Answer

The brainstem connects the brain to the spinal cord, facilitating communication between the brain and the rest of the body.

Question 13

The majority of the cerebral cortex is:
A) fiber tracts.
B) cerebellum.
C) white matter.
D) neocortex.

Accepted Answer

The majority of the cerebral cortex is made up of the neocortex, which is involved in higher-order brain functions such as sensory perception, cognition, and motor control.

Question 14

What are the three primary brain vesicles that form from the neural tube?
A) midbrain, pons, medulla oblongata
B) mesencephalon, telencephalon, diencephalon
C) forebrain, midbrain, hindbrain
D) brainstem, diencephalon, cerebellum

Accepted Answer

The three primary brain vesicles that form from the neural tube are the forebrain (prosencephalon), midbrain (mesencephalon), and hindbrain (rhombencephalon).

Question 15

What best describes the Broca's area?
A) Broca's area is usually found in the right cerebral hemisphere.
B) Broca's area is housed in the temporal and parietal lobes.
C) Broca's area is a premotor area for speech sounds.
D) Broca's area houses personality, decorum, and behavior.

Accepted Answer

Broca's area is a region in the frontal lobe of the dominant hemisphere (usually the left) associated with speech production and language processing. It is considered a premotor area for speech sounds.

Question 16

What is located in the postcentral gyrus of the parietal lobe?
A) primary somatosensory cortex
B) primary visual cortex
C) auditory association area
D) primary auditory cortex

Accepted Answer

The primary somatosensory cortex is located in the postcentral gyrus of the parietal lobe, responsible for processing sensory information from the body.

Question 17

In 1848, Phineas Gage sustained a brain injury when an iron rod pierced through his left prefrontal cerebral cortex. What do you think was the result?
A) Gage was unable to move the right side of his body.
B) Gage's personality, behavior, and psychological state changed.
C) Gage was unable to produce language.
D) Gage was unable to understand language.

Accepted Answer

Phineas Gage's injury to the left prefrontal cortex resulted in significant changes to his personality and behavior, which is consistent with the role of the prefrontal cortex in personality and decision-making.

Question 18

What brain region is responsible for learning, memory, and personality?
A) cerebrum
B) cerebellum
C) brainstem
D) diencephalon

Accepted Answer

The cerebrum is responsible for higher brain functions, including learning, memory, and aspects of personality.

Question 19

What secondary brain vesicles form from the forebrain?
A) metencephalon and mesencephalon
B) diencephalon and telencephalon
C) metencephalon and myelencephalon
D) telencephalon and metencephalon

Accepted Answer

The forebrain, or prosencephalon, develops into the secondary brain vesicles known as the diencephalon and telencephalon.

Question 20

What is the correct pathway of development of the cerebellum?
A) neural tube, forebrain, telencephalon, cerebellum
B) neural tube, midbrain, mesencephalon, cerebellum
C) neural tube, diencephalon, cerebellum
D) neural tube, hindbrain, metencephalon, cerebellum

Accepted Answer

The cerebellum develops from the metencephalon, which is part of the hindbrain, originating from the neural tube.
