Now let's review what we've seen of the brain.
Here's the cerebrum, the cerebellum, and the brainstem. Here are the medulla, the pons, and the midbrain.
Here's the superior medullary velum, the floor of the fourth ventricle, and the inferior medullary velum. Here are the cerebellar peduncles, superior, middle, and inferior. Here are the pyramid, and the olive.
Here are the filaments of the hypoglossal, the cranial part of the accessory, the vagus, and the glossopharyngeal nerves, the vestibulo-cochlear, and facial nerves, the abducent nerve, and the trochlear nerve.
Here are the colliculi, inferior and superior, and the pineal body. Here's the medial geniculate body, the lateral geniculate body, and the optic tract.
On the cerebellum, here's the primary fissure, the anterior, and posterior lobes, the vermis, and the roof of the fourth ventricle.
Here are the cerebral hemispheres, here's the corpus callosum. Here are the frontal, parietal, occipital, and temporal lobes.
Here are the oculomotor nerve, the optic chiasm, the optic nerves, the infundibulum, and the mammillary bodies.
In the model here are the lateral ventricles, the third ventricle, and the fourth ventricle. Here's the third ventricle, the interventricular foramen, the choroid plexus, the cerebral aqueduct, and the fourth ventricle. Here's the hypothalamus. Here's the infundibulum, and the pituitary gland.
