Chapter 9, Problem 2ATP

What do studies of patients with posterior parietal damage tell us about its role in action control?        a.   Action control is mostly acquired through imitation and awareness    b.  Action control relies on linking body state and position with object size and position  c.  Action control is mainly about movement execution  d.  Action control is flexible and stereotyped after extensive learning

Which brain region involved in action control is incorrectly paired with its function?          a.  Prefrontal Cortex (PFC) - Plans and coordinates internal thoughts and external actions    b.  Cerebellum - Motor learning, monitor action online, coordinates the timing and trajectory of movement    c.  Frontal Eye Fields (FEF) - Execution of voluntary eye movements    d.  Supplementary Motor Area (SMA) - Responds to observed and self-enacted action

When you “max out” on reps or pushups or something like that, what kind of stimulus is your brain sending to your muscles by the end of that exercise? Explain your answer please.

Upper motor neuron damage:   Results in activation of the extensor reflex Results in activation of the fight or flight response Results in weakness that becomes spasticity Results in spasticity that becomes flaccidity

What are the five reflex arc components for the Plantar Reflex? Receptor, the type of the receptor, the location The sensory neuron The control center The motor neuron The effector

Name a structure that is located cranial to the Abdominal cavity, caudal to the neck, and dorsal to the sternum. Next, Name a structure that is inferior, perpendicular, and very distal.  If you are testing a patellar reflex, what area are you working on? Mental refers to what part of the body? Can you work with me online because is like quizzes?

In a rock climber like the man pictured in Figure 14.25, which organs of equilibrium are activated? Figure 14.25 Dangling upside down affects several organs of equilibrium. What are they?

Your friend’s cerebral blood vessel burst on account of high blood pressure and a high platelet count. After a few weeks of rehabilitation he can neither feel his fingers nor can he walk easily. Will this lack of sensation and motor abilities ever go away

Located at the “back of the brain” is the __4_____. In the longitudinal cut you are looking at, you’ll notice that it has an internal, tree-like pattern called arbor vitae. This part of the brain coordinates equilibrium and motor activity to produce smooth, controlled movements.
