The vertebral column, or backbone, plays a role in protecting the spinal cord, which is a crucial part of the nervous system.

The brain is vital for a variety of activities, and its delicate nature necessitates careful protection. This protection is achieved through the bony box and the fluid-filled balloon.

The structure felt is the vertebral column or backbone, which protects the spinal cord.

The fluid-filled balloon inside the bony box serves to provide further shock absorption and protection for the delicate organ, the brain.

The brain is protected by a bony box in the body. This box contains the brain and is filled with fluid, which provides additional shock absorption.

The emphasizes that activities like walking, riding a bicycle, and picking up a pencil are possible due to the cerebellum. It further suggests that without the cerebellum functioning properly, these actions would fail to take place even without conscious thinking.

The cerebellum is responsible for the precision of voluntary actions and maintaining the posture and balance of the body.

The cerebellum, a part of the hind-brain, is responsible for these activities.

The mid-brain and hind-brain control a set of muscle movements over which we do not have conscious thinking control. Many involuntary actions, such as those related to muscle movements, are regulated by these brain regions.

Involuntary actions, including blood pressure, salivation, and vomiting, are controlled by the medulla in the hind-brain.
