Neuro 🧠

Hi everyone, and welcome back! Apologies for the short break over the past 2 weeks - I hope everyone's working hard for their year 12 mocks! Today, we're gong to be exploring the cerebellum.

In GCSE biology, we've learn that the cerebellum controls movement and motor activity.

But do you know that it is also the second largest part of the brain?

The cerebellum stands for 'little brain',and it covers 11% of the brain mass. It is located at the back of the brain and consists of two hemispheres which are connected by the vermis (the midline portion of the cerebellum).

There are three lobes in the cerebullum, the anterior lobe, the posterior lobe and the flocculonoular lobe and these lobes are divided by the pirmary fissure and posterolateral fissure. There are also three cerebellar zones as seen from the picture below:

The cerebellum can also be divided by functions:

1) cerebrocerebellum - involved in planning movements and motor learning

2) spinocerebellum - involved in regulating body movement and error corrections

3) Vestibulocerebellum - controlling balance and ocular reflexes

In my next post, we'll be taking a brief pause from our usual content and spending a few sessions exploring MRI images - an exciting way to see the brain in action!
