Question: 1 / 400

What is the main function of the brain stem?

Connects the brain to the spinal cord and controls involuntary movements

The primary role of the brain stem is indeed to connect the brain to the spinal cord and manage involuntary movements such as breathing, heart rate, and digestion. It serves as a critical pathway that facilitates communication between the brain and the rest of the body. The brain stem also houses centers that control various automatic functions essential for survival, making it a crucial part of the central nervous system.

The other functions mentioned in the incorrect options focus on tasks managed by different parts of the brain. Coordination, posture, and balance are functions primarily associated with the cerebellum, not the brain stem. Vision regulation is primarily controlled by the occipital lobe, which processes visual information. Thinking and creativity are associated with higher cognitive functions originating in the cerebral cortex, far removed from the responsibilities of the brain stem.
