Annette’s Story
A) Annette takes medication for her Parkinson’s Disease. What is a characteristic that the medication must have to cross the blood-brain barrier freely?
The medication must be made of a lipid soluble substance, such as oxygen, carbon-dioxide, alcohol and most anesthetic agents. It could also contain glucose and water soluble agents.
B) Which part of the brain is responsible for controlling the initiation and termination of movement?
Basal Ganglia’s most major function is to control the inhibition and termination of movement within the body.
C) What other symptoms that Annette is having is also controlled by this region of the brain?
In addition to controlling initiation and termination of movement, the basal ganglia or basal nuclei also helps regulate muscle tone and controls subconscious contractions of skeletal muscle.
D) Annette has difficulty using her fork to move food from the plate to her mouth. Which are of the brain is not functioning properly to cause this symptom?
The primary and premotor areas of the brain would cause a malfunction causing Annette difficulty moving her hand to her mouth when feeding herself.
E) What part of the brain transmits motor impulses from Annette’s basal nuclei to the primary motor area?
The hypothalamus controls and transmits impulses from the basal nuclei to the primary motor area.
F) Motor Signals from Annette’s primary motor area in her cerebral cortex must travel to her 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 lies directly inferior to the midbrain and anterior to the cerebellum. As its name implies, the pons is a bridge that connects parts of the brain with one another.
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 upholds maintenance of normal
