In order to cross the BBB freely, Annette’s medication must be fat soluble.
B. Which part of the brain is responsible for controlling the initiation and termination of movement?
The basal ganglia of the primary motor area of the brain are primarily responsible for controlling the initiation and termination of movement.
C. What other symptom that Annette is having is also controlled by this region of the brain?

The premotor area of Annette’s brain is not functioning properly and thus is producing these symptoms.
E. What part of the brain transmits motor impulses from Annette’s basal nuclei to her primary motor area?
The thalamus transmits motor impulses from Annette’s basal nuclei to her primary motor area.
F. Motor signals from Annette’s primary motor area in her cerebral cortex must travel to the cerebellum so that she can pick up her fork. What part of the brain serves as a bridge from the cortex to the cerebellum?
The pons serves as a bridge from the cortex to the cerebellum.
G. Parkinson’s disease is causing Annette’s muscles to become increasingly rigid or hypertonic. Maintenance of normal muscle tone is controlled by which part of Annette’s brain?
The cerebellum maintains normal muscle tone.
H. Which of the meninges did Dr. Paynter have to drill through during the procedure?
Dr. Paynter had to drill through the dura mater during the procedure.
