Science
There was a cerebellar dysfunction in a patient. Which of the following activities will get disturbed in this patient as a result of this?
options
- Salivation
- Hunger control
- Posture and balance
- Regulation of blood pressure
Answer
Posture and balance
Reason — The cerebellum is the part of the brain responsible for maintaining balance, posture and coordination of voluntary movements so it ensures that body movements are smooth, precise and well-controlled.
If there is cerebellar dysfunction, the person may experience loss of balance, unsteady gait, poor coordination and difficulty in maintaining posture.
The other functions—salivation, hunger control and blood pressure regulation—are managed by different parts of the brain such as the medulla and hypothalamus, not the cerebellum.
Hence, posture and balance are the activities most affected by cerebellar dysfunction.
