Which structure includes the midbrain, pons, and medulla?

• A. Cerebellum
• B. Cortex, Occipital lobe
• C. Brainstem
• D. Peripheral nerves

Answer: (C)

The midbrain, pons, and medulla are all parts of the brainstem, the stalk-like portion of the brain that connects the cerebrum with the spinal cord. This region serves as a major conduit for most motor and sensory pathways traveling between the brain and the body and houses essential autonomic and cranial nerve centers. The cerebellum sits behind the brainstem and coordinates movement, but it is a separate structure. The cerebral cortex forms the outer layer of the cerebrum and handles higher cognitive functions, not the brainstem. The peripheral nerves belong to the peripheral nervous system, outside the brain and spinal cord, so they are not part of the brainstem either.
