Document Summary
Forebrain: telencephalon lateral ventricle principal structures: cerebral cortex, basal ganglia, limbic system, diencephalon third ventricle principal structures: thalamus and hypothalamus. Midbrain: mesencephalon ventricle cerebral cortex principal structures tectum, tegmentum. Hindbrain: metencephalon fourth cerebellum and pons, myelencephalon fourth medulla oblongata. 5 subdivisions telencephalon; diencephalon; mesencephalon; metencephalon; myelencephalon. Myelencephalon: ventral side of brain, medulla oblongata. Cerebral aqueduct part of the ventricular system. Peri-aqueductal gray controls how you do not feel pain until you are safe; Substantia nigra dark substance ; disappears in parkinson"s patients.
