Question 1

Someone with Huntington's disease often shows uncontrollable twisting and writhing contractions movements, which is captured by which of the following motor symptoms:&#10;A)Atheosis&#10;B)Decomposition of movement&#10;C)Bradykinesia&#10;D)Akinesia

Accepted Answer

Athetosis is characterized by slow, involuntary, convoluted, writhing movements of the fingers, hands, toes, and feet, and sometimes arms, legs, neck, and tongue, which can be seen in conditions like Huntington's disease.

Question 2

The medial pathway linking the brain to the muscles controls what kind of movements?&#10;A)Movement of the arms, hands and fingers&#10;B)Movement of the lower leg and foot&#10;C)Movement of the trunk and proximal limb muscles&#10;D)Movement of the head

Accepted Answer

The medial pathway is primarily responsible for controlling gross movements of the trunk and proximal limb muscles, facilitating posture and balance adjustments.

Question 3

Which of the following is true regarding the frontal eye field?&#10;A)It is involved the planning voluntary execution of eye movements&#10;B)It is involved in the execution of involuntary eye movements&#10;C)It is involved in both voluntary and involuntary eye movements&#10;D)It is involved in neither voluntary nor involuntary eye movements.

Accepted Answer

The frontal eye field is primarily involved in the planning and voluntary execution of eye movements. It plays a crucial role in directing gaze according to cognitive demands, rather than being involved in involuntary eye movements.

Question 4

If you sustained damage to your right ventrolateral prefrontal cortex what type of behavioural deficits would you most likely exhibit:&#10;A)Difficulty with novel motor movements&#10;B)Difficulty with coordinated and sequenced movements&#10;C)Difficulties reaching and grasping&#10;D)Difficulty with response inhibition

Accepted Answer

The right ventrolateral prefrontal cortex is associated with response inhibition and control, so damage to this area would likely result in difficulties with inhibiting responses.

Question 5

Parietal regions process proprioceptive information, which is characterized by the following:&#10;A)Motor feedback after inaccurate motor coordination&#10;B)Sensory information about the movements of body parts&#10;C)Sensory information about the spatial relation of body parts&#10;D)Simulation of planned motor movement before execution

Accepted Answer

The answer of Parietal regions process proprioceptive information, which is...

Question 6

Which of the following roles does the superior parietal lobe play in movement?&#10;A)It is important for determining the type of grasping motion used to manipulate objects.&#10;B)It is important for determining how forceful movements area.&#10;C)It is important in guiding movements to particular regions of space.&#10;D)It regulates the speed with which movements are made.

Accepted Answer

The superior parietal lobe is involved in integrating sensory information and is crucial for guiding movements to specific regions of space, helping to coordinate spatial awareness and motor planning.

Question 7

Someone with ideomotor apraxia would have the most difficulties with which of the following:&#10;A)Saluting the flag&#10;B)Dressing themselves&#10;C)Sticking out their tongue&#10;D)Lighting a candle

Accepted Answer

Ideomotor apraxia is a neurological disorder that affects the ability to perform purposeful movements. People with ideomotor apraxia have difficulty planning and executing complex movements, even though they understand what they want to do and have the physical ability to do it. Saluting the flag is a complex movement that requires planning and coordination, so someone with ideomotor apraxia would have difficulty performing this task.

Question 8

Which of the following statements regarding apraxia is true?&#10;A)It primarily affects more automatic motor behaviors&#10;B)It affects fine skilled motor movements that are sequential in nature&#10;C)It affects gross motor movements that are sequential in nature&#10;D)It mainly affects the ability to perform multiple motor movements simultaneously.

Accepted Answer

Apraxia specifically impacts the ability to perform fine, skilled motor movements that are sequential in nature, such as buttoning a shirt or writing, rather than gross motor movements or the ability to perform multiple motor movements simultaneously. It is a motor disorder caused by damage to the brain (specifically in areas involved in planning the movements needed to perform tasks) that affects the execution of learned movements, despite having the desire and the physical ability to perform the movements.

Question 9

Which of the following would not be affected by damage to the cerebellum?&#10;A)Speech&#10;B)Motor coordination&#10;C)Motor learning&#10;D)Pantomime

Accepted Answer

The answer of Which of the following would not be...

Question 10

What is the name for the specialized synapse between a neuron and muscle fibers?&#10;A)Muscle junction&#10;B)Motor unit&#10;C)Neuromuscular junction&#10;D)Motor junction

Accepted Answer

The neuromuscular junction is the specialized synapse between a neuron and muscle fibers, facilitating the transmission of the nerve impulse to the muscle to induce contraction.

Question 11

Which cortical region is responsible for controlling the force and/or direction with which the motor plans are executed?&#10;A)Primary motor cortex&#10;B)Premotor region&#10;C)Anterior cingulate&#10;D)Parietal regions

Accepted Answer

The answer of Which cortical region is responsible for controlling...

Question 12

Akinesia, bradykinesia and tremors, are characteristic of which disease?&#10;A)Huntingdon's disease&#10;B)Epilepsy&#10;C)Dysarthria&#10;D)Parkinson's disease

Accepted Answer

The answer of Akinesia, bradykinesia and tremors, are characteristic of...

Question 13

Which subcortical region of plays an important role in the coordination of muscle movement timing, planning of movements and learning of motor skills?&#10;A)Cerebellum&#10;B)Brainstem&#10;C)Thalamus&#10;D)Basal ganglia

Accepted Answer

The answer of Which subcortical region of plays an important...

Question 14

Which of the regions below is one of the main regions of the brain that plays a role in planning, preparing, and initiating movements?&#10;A)Primary motor cortex&#10;B)Supplementary motor cortex&#10;C)Parietal regions&#10;D)Anterior cingulate

Accepted Answer

The answer of Which of the regions below is one...

Question 15

Which region of the brain is primarily affected in Parkinson's disease?&#10;A)Substania Nigra&#10;B)Caudate&#10;C)Subthalamic Nucleus&#10;D)Motor Cortex

Accepted Answer

The answer of Which region of the brain is primarily...

Question 16

The caudate nucleus, putamen, and nucleus accumbens are all part of which subcortical structure?&#10;A)Substantia nigra&#10;B)Cerebellum&#10;C)Basal ganglia&#10;D)Subthalmic nucleus

Accepted Answer

The answer of The caudate nucleus, putamen, and nucleus accumbens...

Question 17

Which cortical region is important for selecting among conflicting responses and monitoring whether the execution of those actions occurred appropriately?&#10;A)Primary motor cortex&#10;B)Premotor region&#10;C)Anterior cingulate&#10;D)Parietal regions
