3 Functions and Abnormalities of the Cerebellum
Windowofworld.com – Despite its name, the cerebellum has a great functions for the body. The organ, located at the back of the head, functions to regulate cooperation between muscles, control balance, and maintain body posture.
cerebellum is located behind the head, precisely under the occipital lobe of the cerebrum. Disorders of these organs can not only affect your ability to move, but also your ability to speak.
Various Cerebellum Functions
The size of the cerebellum is only 10% of the whole brain. Even so, the cerebellum contains more than 50% of nerve cells in the brain. The cerebellum has many functions related to body movements. More precisely, it is this organ that perfects signals from the cerebrum to muscles and makes body movements more accurate.
The following are some of the functions of the cerebellum that you need to know:
1. Maintain balance and posture
The cerebellum receives information from the body about the position and whereabouts of each limb. Through this information the cerebellum processes and perfects the movement commands of the cerebrum so that the body becomes balanced.
For example, walking on a sloping road certainly requires a different muscle strength than on a flat road. In situations like this, the foot sends a signal that “reports” that we are walking on a sloping road.
The cerebellum then processes these signals and regulates the muscles in such a way that we don’t fall while walking.
2. Regulate coordination and body movements
Almost every body movement requires coordination of several muscle groups. The brain is what regulates the strength of several different muscles at one time so as to produce a smooth motion.
One example of the function of the cerebellum can be seen from people who are drunk. Alcohol has a direct effect on the cerebellum. This is what causes people to get very drunk sometimes can not control their movements.
3. Regulate the learning process of movements and cognitive functions
Cerebellum plays an important role in the process of motor learning. This brain records the repetitive movements and perfects them in each experiment until the body is accustomed to the movements. The function of this little brain can be seen in someone who is learning to ride a bicycle.
In addition, the cerebellum is also involved in one’s language skills.
Beware of Triggers Cerebellum Disorders
Impaired cerebellum can cause ataxia, which is a condition when a person loses the ability to maintain balance, coordinate his limbs, and speak. This damage can occur due to:
- Severe head injuries, for example due to falls or traffic accidents.
- Bacterial infections of the brain, such as encephalitis and meningitis.
- Viral infections, such as measles or chicken pox, which attack the brain (rarely).
- Impaired blood supply to the brain due to cerebral blood vessels blocked (ischemic stroke) or rupture (hemorrhagic stroke).
- Other conditions, such as cerebral palsy, multiple sclerosis, hypothyroidism, brain tumors or certain cancers.
Some other symptoms that may occur when the function of the cerebellum are disrupted are decreased muscle control, difficulty walking, difficulty speaking and swallowing, and uncontrolled eye movements (nystagmus).
Tips for Maintaining Cerebellum Function
As a vital and most complex organ, the brain must always be protected and maintained in good health. The following are some tips that you can do to maintain brain health and sharpen their abilities:
- Protect your head with a helmet when riding on a bicycle or motorcycle, when doing sports that are prone to collisions, or when you are in a work area with a high risk of being hit by something.
- Doing exercise regularly.
- Eat a variety of healthy foods, especially foods high in calcium and potassium which are good for the nervous system.
- Perform activities that challenge brain work, such as dancing, playing musical instruments, and filling in crosswords.
- Stop smoking or consuming alcoholic beverages.
The function of the cerebellum is often not realized. However, once this function is disrupted, the effect will be so great on the body. Therefore, it is important for you to maintain the functioning of the cerebellum and also overall brain health.
If you experience complaints such as loss of balance, difficulty walking, or frequent falls, immediately consult your condition with your doctor so that the cause of the complaint can be immediately identified and treated.
