Document Summary

Myelencephalon: 9 medulla: vital functions e. g. breathing and hearing, reticular formation: Metencephalon: 8 cerebellum: controls motor movements incl. how we move/walk/talk, 7 pons: helps relay messages from the cortex and cerebellum e. g. sleep and temp. regulation. Mesencephalon: tectum: roof of the midbrain, auditory reflexes: inferior colliculi, visual reflexes: superior colliculi, tegmentum: function in voluntary movement esp. movements in the eye/auditory and visual processing (3 structures) _: substantia nigra (receptors for dopamine, red nucleus. Forecebrain: encompasses the cerebral cortex and the four lobes. Diencephalon: 2 thalamus: process sensory input e. g. smell acts as a relay station, 6 hypothalamus: (below the thalamus) basic sensory input e. g. motivation and behavior, basal ganglia: motor control, motor learning, executive functions. Telecephalon: cerebral cortex: thinking, perceiving, producing and understanding language four lobes, 3 corpus callosum: connects the two hemispheres of the cerebellum. 4 pineal body: regulation of sleep and sex. 5 fornix: bridge between the hippocampus (learning and memory) and hypothalamus.
