Question 1

The massive fiber bridge between the left and right cerebral hemispheres is:&#10;A) The cerebellum&#10;B) The corpus callosum&#10;C) The Longitudinal Fissure&#10;D) The Sylvian Fissure

Accepted Answer

The corpus callosum is the large, C-shaped nerve fiber bundle found beneath the cerebral cortex, stretching across the midline of the brain, connecting the left and right cerebral hemispheres. It facilitates communication between the two sides.

Question 2

What are some major landmarks of the brain?

Accepted Answer

Possible responses are: the four lobes of each hemisphere and the cerebellum; the Sylvian Fissure, the Longitudinal Fissure, and the Central Sulcus; the brainstem, the corpus callosum, and the ventricles.

Question 3

Three parts of a neuron are&#10;A) The axon, the soma, and the dendrites&#10;B) The axon, the synapse, and the medulla&#10;C) The dendrites, the pons, and the axon&#10;D) None of the above

Accepted Answer

The neuron consists of three main parts: the axon, which transmits signals away from the neuron's cell body; the soma, or cell body, which contains the nucleus and metabolic machinery for the cell; and the dendrites, which receive signals from other neurons.

Question 4

The thalamus is a key structure in the brain. Which of the following is true about the thalamus?&#10;A) There are two thalami: one in the left hemisphere and one in the right&#10;B) Along with the cortex, it forms a key hub&#10;C) The right and left hemisphere thalami are interconnected with all four lobes in their hemisphere&#10;D) All of the above

Accepted Answer

The thalamus is indeed a bilateral structure, with one located in each hemisphere of the brain, making it a key hub in conjunction with the cortex. Additionally, each thalamus is interconnected with all four lobes (frontal, parietal, temporal, and occipital) in its respective hemisphere, facilitating the relay and processing of sensory and motor signals.

Question 5

Which of these brain terms are describing a similar place in the brain?&#10;A) Superior frontal lobe and dorsal frontal lobe&#10;B) Inferior temporal lobe and dorsal temporal lobe&#10;C) Anterior parietal lobe and ventral occipital lobe&#10;D) Posterior occipital lobe and superior parietal lobe

Accepted Answer

The terms "superior" and "dorsal" both refer to the upper part of the brain structure, making A the correct choice as both terms describe a similar location in the frontal lobe.

Question 6

The 'executive functions' of planning and initiating activities are key processes of the&#10;A) The temporal lobe&#10;B) The parietal lobe&#10;C) The frontal lobe&#10;D) The occipital lobe.

Accepted Answer

The frontal lobe is responsible for executive functions, which include planning, decision-making, problem-solving, and initiating activities. These cognitive processes are crucial for goal-directed behavior.

Question 7

The brain is typically 'sliced' into three planes:&#10;A) Ventral, dorsal, and medial&#10;B) Sagittal, coronal, and axial&#10;C) Frontal, temporal, and parietal&#10;D) Coronal, dorsal, and horizontal

Accepted Answer

The brain is typically sliced into three planes for imaging and anatomical study: sagittal (divides the brain into left and right halves), coronal (divides the brain into front and back), and axial (divides the brain into upper and lower parts).

Question 8

The four lobes of the cortex are the:&#10;A) Temporal, parietal, occipital, and frontal&#10;B) Frontal, medial, dorsal, and ventral&#10;C) Sagittal, medial, coronal, and axial&#10;D) Inferior, superior, anterior, and posterior

Accepted Answer

The four lobes of the cortex are the temporal, parietal, occipital, and frontal lobes. These are major regions of the brain, each associated with different functions such as sensory processing, motor skills, and cognitive abilities. Choices B, C, and D list orientations or divisions used in anatomy and brain imaging, not specific lobes of the cortex.

Question 9

One way to describe the sulci and gyri in the cortex is&#10;A) Sulci are small bumps and gyri are small grooves&#10;B) Sulci are gray matter and gyri are white matter&#10;C) Sulci are small grooves and gyri are small bumps&#10;D) Sulci are white matter and gyri are gray matter

Accepted Answer

Sulci and gyri are features of the brain's surface: sulci refer to the grooves or indentations, while gyri are the raised ridges or bumps. These structures increase the surface area of the cerebral cortex, allowing for a greater number of neurons within a limited space.

Question 10

What role does the prefrontal cortex play in human cognition?

Accepted Answer

The answer of What role does the prefrontal cortex play...

Question 11

The brainstem connects the brain to the spinal cord. The three major regions of the brainstem are:&#10;A) The midbrain, the lower brain, and the upper brain&#10;B) The midbrain, the pons, and the medulla&#10;C) The upper brain, the midbrain, and the medulla&#10;D) The lower brain, the spinal brain, and the midbrain

Accepted Answer

The answer of The brainstem connects the brain to the...

Question 12

A key subcortical body for emotional processing is the&#10;A) Basal ganglia&#10;B) Amygdala&#10;C) Thalamus&#10;D) Hippocampus
