1 Click to Play! Neuro Quiz  Michael McKeough 2008 Identify the correct question The Motor System

2 Motor System Neuro Quiz Dorsolateral Motor System Ventromedial Motor Neurons Misc.MotorControlCenters Click category value to begin.

3 Dorsolateral Motor System 100 Learned, willed, skilled movements, particularly of the hand. What are the types of movement (functions) controlled by the dorsolateral motor system? Return to Return to Game Board Game Board Click to reveal the question

4 Dorsolateral Motor System 200 The cell bodies of these neurons are located in somatically organized areas of the precentral gyrus. The axons of these neurons travel in the lateral corticospinal tract. What are upper motor neurons? Return to Return to Game Board Game Board Click to reveal the question

5 Dorsolateral Motor System 300 The cell bodies of these neurons are located in somatically organized areas of the ventral horn. The axons of these neurons travel in the peripheral nervous system and innervate skeletal muscle. What are lower motor neurons? Return to Return to Game Board Game Board Click to reveal the question

6 Dorsolateral Motor System 400 Upper motor neurons cross the midline (decussate) after passing through this structure. What is the medullary pyramid? Return to Return to Game Board Game Board Click to reveal the question

7 Dorsolateral Motor System 500 Approximately 10% of upper motor neurons have this relationship with lower motor neurons. What are monosynaptic connections? Return to Return to Game Board Game Board Click to reveal the question

8 Ventromedial Motor System 100 These are the types of movement (functions) controlled by the ventromedial motor system. What are tone, posture, and associative movement? Return to Return to Game Board Game Board Click to reveal the question

9 These tracts comprise the ventromedial motor system. Ventromedial Motor System 200 What are the tectospinal, reticulospinal, vestibulospinal, and ventral (anterior) corticospinal tracts? Return to Return to Game Board Game Board Click to reveal the question

10 Uppermotor neurons in the ventromedial motor system terminate here. Upper motor neurons in the ventromedial motor system terminate here. Ventromedial Motor System 300 What are the ventromedial lower motor neuron pools, bilaterally? Return to Return to Game Board Game Board Click to reveal the question

11 This tract is located in the anterior column (funiculus) and consists of upper motor neurons originating in the ipsilateral primary motor cortex. Ventromedial Motor System 400 What is the ventral (anterior) corticospinal tract? Return to Return to Game Board Game Board Click to reveal the question

12 Ventromedial Motor System 500 This pathway originates in the brainstem, descends in the lateral column (funiculus) and is concerned with the control of posture (particularly extensor muscles) as well as the coordination of head and eye movement. What is the lateral vestibulospinal tract? Return to Return to Game Board Game Board Click to reveal the question

13 Motor Neurons 100 They convey movement commands from motor control centers in the cortex and brainstem to lower motor centers located at segmental levels of the neuraxis. What are upper motor neurons ? Return to Return to Game Board Game Board Click to reveal the question

14 Motor Neurons 200 They are located in the peripheral nervous system and convey movement commands from cranial nerve nuclei or the ventral horn of the spinal cord to skeletal muscle in the head and body, respectively. What are lower motor neurons ? Return to Return to Game Board Game Board Click to reveal the question

15 Motor Neurons 300 They are located in the peripheral nervous system and convey movement commands from cranial nerve nuclei or the ventral horn of the spinal cord to extrafusal muscle fibers in the head and body, respectively. What are alpha lower motor neurons? Return to Return to Game Board Game Board Click to reveal the question

16 Motor Neurons 400 They are located in the peripheral nervous system and convey movement commands from segmental motor control centers to intra- and extrafusal muscles fibers, simultaneously. They couple the alpha and gamma motor systems They are more common in reptiles than mammals. Return to Return to Game Board Game Board Click to reveal the question What are beta lower motor neurons?

17 Motor Neurons 500 They increase the sensitivity of intrafusal muscles fibers to the phasic portion of a change in muscle length. What are dynamic gamma motor neurons? Return to Return to Game Board Game Board Click to reveal the question

18 Miscellaneous 100 This physiological mapping of the cortex depicts a distorted representation of the body. Body parts are portrayed proportional to the amount of brain space dedicated to the control of movement of that body part. Return to Return to Game Board Game Board Click to reveal the question What is the motor homunculus?

19 Miscellaneous 200 This spinal pathway originates in the contralateral cerebral cortex and is concerned with the control of manipulation and fractionated movement of distal limb segments (particularly the hand). What is the lateral corticospinal tract? Return to Return to Game Board Game Board Click to reveal the question

20 Miscellaneous 300 This pathology causes brain damage that produces limitations in the ability to move due to paresis and spasticity. The movement deficits caused by this pathology appear on the side of the body opposite the brain damage. What is a stroke or cerebrovascular accident? Return to Return to Game Board Game Board Click to reveal the question

21 Miscellaneous 400 The type of hand movement controlled by the corticospinal tract. Independent control of individual digits including terminal opposition of the thumb and individual digits. What is the fractionated movement? Return to Return to Game Board Game Board Click to reveal the question

22 Miscellaneous 500 This system auto-regulates (reflexively) joint position. This system provides feedback about the alpha motor system (muscle tension and muscle length). What is the gamma motor system? Return to Return to Game Board Game Board Click to reveal the question

23 Motor Control Centers 100 Located in the precentral gyrus. Somatotopically organized. Controls learned, willed, skilled movements of the contralateral body. What is the primary motor cortex? Return to Return to Game Board Game Board Click to reveal the question

24 Motor Control Centers 200 Located in the cortex of the frontal lobe. Responsible for controlling voluntary eye movement. What is the frontal eye field? Return to Return to Game Board Game Board Click to reveal the question

25 Motor Control Centers 300 Located in the cortex of the frontal lobe, usually in the left hemisphere. Responsible for speech production. Lesions here cause non-fluent (productive) aphasia. What is Brocha’s area? Return to Return to Game Board Game Board Click to reveal the question

26 Motor Control Centers 400 Located at the base of the telencephalon in both hemispheres. Responsible for controlling initiation, termination, and scaling of internally generated movements. Lesions here cause Parkinson's disease. What are the basal ganglia? Return to Return to Game Board Game Board Click to reveal the question

27 Motor Control Centers 500 Located on the dorsal surface of the brainstem. Responsible for the timing and coordination of complex movements and detecting movement errors. What is the cerebellum? Return to Return to Game Board Game Board Click to reveal the question
