Structure and Function
It would be easy to write 10,000 words on the structure of the cerebellum; none of this is likely to be relevant clinically.
The cerebellum plays an important role in learning and co-ordinating motor functions.
It is basically a motor spell check: it reads the brainstem
through its connecting peduncles, looks at the motor and sensory information running up and down, and puts it all together to shout "You are going to fall over unless you contract this, this and this muscle!"
When cerebellums go wrong
There are a series of key symptoms seen in people with cerebellar disease/infarcts. They love to test this in exams, so learn VANISH'D, and learn how to examine it:
- Intention tremor
- Slurred speech
Arterial and Venous supply
- Superior cerebellar artery (SCA)
- Anterior inferior cerebellar artery (AICA)
- Posterior inferior cerebellar artery (PICA)
