Question

external brain structures select a region of the model or an answer below... cerebellum left occipital lobe medulla oblongata pons corpus callosum hypothalamus right occipital lobe left orbital gyrus right superior frontal gyrus

Explanation:

The image shows a brain model and a list of external brain structures. The checked items (Cerebellum, Left Occipital Lobe, Medulla Oblongata, Pons) are correctly identified as external brain regions. For example, the cerebellum is at the back/below the cerebrum, the occipital lobes are part of the cerebral cortex (external), medulla oblongata and pons are in the brainstem (external to the cerebrum's inner structures like corpus callosum which is internal).

Answer:

The checked structures (Cerebellum, Left Occipital Lobe, Medulla Oblongata, Pons) are correctly identified as external brain regions. If the task was to identify external brain structures, these are valid as: Cerebellum (involved in motor control, external posterior), Left Occipital Lobe (part of cerebral cortex, external, processes vision), Medulla Oblongata (brainstem, external, controls vital functions), Pons (brainstem, external, relays signals).
