Question

Tina is a ballerina. Which part of the brain is responsible for her graceful movements, posture, and balance?

brain stem
frontal lobe
cerebellum
parietal lobe

Answer 1

cerebellum

Step-by-step explanation:

Cerebellum (Latin for little brain) is located at the back of the brain and affects motor functions and movement.

Movements and motor functions are not initiated by the cerebellum but are modified by it. If the cerebellum is hurt, motor functions are affected because this part of the brain is in charge of:

1. balance and posture - cerebellum maintains these functions and maintains the balance of the body and movement.
2. coordination of the movements - the movement we decide to make have to be coordinated by timing and focus, and this function is affected by cerebellum
3. motor learning - cerebellum adapts accuracy of the movements and helps in the process of learning movements

All these functions help the motion functions and movings of the body, which is why normal physical coordination can't be possible without correct functioning of the cerebellum
