Document Summary
Telencephalon: cerebrum: cerebral hemispheres (cortex, white matter, basal nuclei, lateral ventricles. Diencephalon: thalamus, hypothalamus, epithalamus, retina, third ventricle. Mesencephalon: brain stem: midbrain, cerebral aqueduct. Carries water between third and fourth ventricles. Metencephalon: brain stem: pons, cerebellum, fourth ventricle. Myelencephalon: brain stem: medulla oblongata, fourth ventricle. Brain grows so fast that it outpaces amount of space it has to grow. Gray matter= neuron cell bodies: cortex over cerebrum and cerebellum and central portion of spinal cord, forms nuclei deep within brain. White matter= bundles of axons: forms tracts that connect parts of brain, ascending and descending tracts in the spinal cord. Lateral ventricle, third ventricles, cerebral aqueduct, fourth ventricle. Connected to one another and to central canal of spinal cord. Lateral aperture and median aperture are associated w/ fourth ventricle: allows csf to leave ventricles and surround the brain. Frontal lobe: newest lobe of the brain, central sulcus separates it from parietal love.
