The cerebellum is a part of the human brain. It is the part of the brain that that is responsible for human movement, co-ordination, motor control and sensory perception. The cerebellum is in the lower posterior part of the brain which looks almost like it is separate but still of the same unit. The cerebellum receives signals from all over the body through neural pathways to keep the mind aware of where the body is positioned and how the body is coping with its environment at any one point in time though continuously.
The cerebellum is responsible for relaying messages about posture, equilibrium, movement and fine motor skills such as writing or catching a ball. It is a very important part of the brain that keeps us aware of our surroundings and therefore alive. Voluntary movement is monitored and initialized by the cerebellum through the manipulation of fine muscle movement. Cerebellum injuries can lead to forms of paralysis in many various ways such as paraplegic, quadriplegic or partial impairment of the motor neuron pathways.
The brain is surrounded by billions of neuron though the cerebellum has the most neurons compared to any other part of the brain. When excessive alcohol abuse affects the brain it is usually the cerebellum that is affected the greatest and this is why alcohol related brain damage causes permanent slurred speech loss of balance or co-ordination. We notice this effect the most because these are the most important aspects of life that we use the largely.
