Exam 7: The Motor System

Startle and escape reflexes would be compromised if damaged occurred to the _____, cutting off input from the reticular formation.

Much of the knowledge we have about the motor cortex was discovered by neurosurgeons Penfield and Jasper while working on patients with:

Basket cells and stellate cells are both lateral inhibitory connections, which means that they run perpendicular to the excitatory parallel fibers.

An example of deep tendon reflex is:

Damage to the medial prefrontal cortex may result in alien hand syndrome.

Basket cells and _______ send connections across multiple Punkinje cells and are located in the molecular layer of the cerebellum.

Type I muscle fibers are slow-twitch, and therefore are used for:

Muscle fibers used for endurance activities are referred to as:

Recent studies show that rather than body parts, the __________ seems to code for different categories of action.

Muscle fibers are arranged into bundles. These bundles are called:

Basal ganglia are grey matter structures that lie within the:

Areas of the anterior motor cortex that tend to control functions of the eye are typically located at the ____ part of the given brain region, whereas the areas that tend to control the functions of the mouth are typically located at the ____ part of the given brain region.

Basal ganglia have both __________ circuitry for modulating cortical activity.

The polio virus and the West Nile virus effect the motor neurons in the:

Complex, conditional forms of behavior are handled by the more ____ region of the prefrontal cortex.

During muscle contraction, acetylcholine is released into the:

What is alien-hand syndrome and what can it teach us about voluntary and involuntary movement?

Tension is maintained in muscle fibers by the:

Posture and balance would be compromised if damaged occurred to the _____, cutting off input from the vestibular nuclei.

Before muscle contraction, this must be generated in the lower motor neurons:
