Question

Name the part of the brain responsible for the precision of voluntary actions and maintaining body posture and balance of the body.

Answer 1

Hint: A part of the hindbrain is responsible for maintaining body postures and equilibrium of the body. Voluntary actions are controlled by the hind part of the brainstem.

Complete answer:
The cerebellum is the part of the hindbrain that relays impulses for movement and locomotion from the motor area of the brain to the spinal cord and passes responses to the respective muscle groups. It can store the sequence of the instructions for coordinated movements. It is located near the brainstem. It is the part of the brain that is responsible for controlling and coordinating voluntary movements. It does not control involuntary actions. It also controls and maintains various motor functions such as posture, coordination, and balance. The cerebellum is divided into three different functional areas- cerebrocerebellum, spinocerebellum, and vestibulocerebellum. The cerebellum is also known as the little brain and if it is damaged then it can lead to loss of motor functions, inability to stop and judge the distance, rapid movements can’t be performed, and intention movement tremors.

Note: Cerebellum plays a vital role in all the physical movements. It helps in making postural adjustments, coordination of voluntary movements, motor learning, and cognitive functions. The cerebellum is located in the hindbrain and helps in passing information from the brain to the area of action i.e. muscles. It has three areas that help in performing different functions.
