what is the function of cerebellum?

 The ce re be ll um is a portion of the brain located at the base which controls co or di na ti on and balance.

The ce re be ll um is the second largest part of your brain. Its lining is called the ce re be ll ar cortex. Its main functions are balance, co or di na ti on, muscle tension, posture, balance of limbs, fine motion control, and eye movement

The cerebellum processes input from other areas of the brain, spinal cord and sensory receptors to provide precise timing for coordinated, smooth movements of the skeletal muscular system. A stroke affecting the cerebellum may cause dizziness, nausea, balance and coordination problems

The cerebellum is located at the base of the brain, just above the brain stem, where the spinal cord meets the brain, and is made of two hemispheres. The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth, balanced muscular activity. It is also important for learning motor behaviors. It is a relatively small portion of the brain -- about ten percent of the total weight, but it contains half the brain's neurons. The cerebellum is not unique to humans. Evolutionarily speaking, it is an older portion of the brain, as it is present in animals that scientists believe evolved before humans. Damage to the cerebellum, while not causing paralysis or intellectual impairment, would contribute to a lack of balance, slower movements, and tremors. Complex physical tasks would become unsteady and halting.

The function of cerebellum are:-
  1. It controls the regulation of muscle tone.
  2. It helps in maintaining the posture and balance of the body.
  3. It also enable us to make precise and accurate movements.
  4. It coordinates smooth body movements such as walking, riding a bicycle, dancing, picking up of pencil, throwing ball etc.
  5. it helps the motor cortex in planing and programming of movements.
Hope! this will helpful to you..!!
Thanks!!

Cerebellum 1. It is the second largest part of the brain, forming one eighth of its mass. 2. It is a part of the hindbrain. 3. It consists of two cerebellar hemisperes and a median vermis. 4. White matter form arbor vitae. 5. It maintains posture and equilibrium.
hope it helpss.....*-*

It maintains posture ,equilibrium ,muscle tone.It coordinates the voluntary movements initiated by cerebrum.

The cerebellum is located behind the top part of the brain stem (where the spinal cord meets the brain) and is made of two hemispheres (halves).



The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity. It is also important for learning motor behaviors.

It is a relatively small portion of the brain -- about ten percent of the total weight, but it contains roughly half of the brain's neurons, specialized cells that transmit information via electrical signals.

The cerebellum is not unique to humans. Evolutionarily speaking, it is an older portion of the brain. It is present in animals that scientists believe existed before humans.

Damage to the cerebellum, while not causing paralysis or intellectual impairment, might lead to a lack of balance, slower movements, and tremors (shaking). Complex physical tasks would become unsteady and halting.
