Exam 7: The Motor System

Humans use only 10% of their brain.

What is the term for movements triggered automatically by outside stimuli, such as the example of peeling and eating an apple without feeling hungry?

The Medullary Pyramids are the name for the axon bundles of the corticospinal tract at the levels of the:

Explain why brain stimulation experiments (such as those done during surgery) are critical for establishing casual roles between brain activity and cognitive functioning.

Complicated movements are directed by the premotor cortex, whereas simple movements are directed by the:

The medial premotor cortex seems to be linked to internal stimuli, whereas the ______ premotor cortex seems to be linked to external stimuli.

Multitasking, planning and pursuing current and future goals, and decision making are all controlled in part by the:

The limbic loop of the Basal ganglia is involved with:

The telencephalon holds grey matter structures known as the:

Central pattern generators can be found in the:

If an individual is suffering from cerebral palsy, what difficulty will occur in the motor system?

Shorter muscle fibers will result in faster:

If damage occurred to the rubrospinal tract, disrupting the input from red nuclei, what functions would be effected?

The cerebellum influences the motor activity of upper and lower motor neurons through outputs projected from the:

Describe and give an example for 3 of the 5 basal ganglia-cortical loops.

Which of these needs to happen for a muscle to contract?

The corticospinal tract connects the upper motor neurons to the:

Derivations of curare, a toxin, are used in the making of:

The substantia nigra provides _____ inputs to the Basal Ganglia.

The Basal ganglia take part in both motor control and in higher-level cognition.
