Can you confidently say what/ where these are…
- Lateral ventricle [may be cut through twice in horizontal or coronal plane]
- Third ventricle [may look like a hole or a slit in coronal and horizontal plane, depending on angle of section]
- Fourth ventricle
- Aqueduct
- Corpus callosum [may be cut through twice in horizontal plane]
- Frontal lobe
- Occipital lobe
- Parietal lobe
- Temporal lobe
- Basal ganglia [may be more than one part]
