Nuclei and ventricles

• lateral and 3rd ventricles communicate via interventricular foramen of monroe
• 4th and 3rd communicate via cerebral aqueduct of sylvius
• 4th ventricle communicates with the subrachnoid space via foramen of luscka and magendie
• csf isn made by choroid plexus in the ventricles travels to subarachnoid space via foramen of luscka and magendie and reabsorbed by arachnoid granulations and drained by dural venous sinuses
• occulomotor and trochlear nerve are in teh midbrain
• trigeminal abducent facial vestibulocochlear are in tthe pons
• vagus glossopharyngeal accessory spinal hypoglossal are in the medulla
• pineal gland for meltonin secretion and circadian rhythm
• superior colliculus for moving eyes to stimuli
• inferior colliculus for hearing
• nucleus of accessory spinal nerve is in the spinal cord
• nucleus of trigeminal facial abducens and vestibulocochlear are in the pons
• nucleus of the vagus hypoglossal glossopharyngeal are in the medulla
• nucleus of the occulomotor and trochlear are in the pons
• olfactory nerve and optic nerve are above the pons
• nucleus tractus solitarius for visceral sensory information like taste baroreceptors gut distention plays role in vomitting
• nucleu ambigus is for motor inervation of the pharynx larynx upper esophagus ( swallowing and palate elevation)
• dorsal motor nucleus sends parasympathetic fibers to heart lungs and upper gi via vagus
• superior colliculus cerebral aqueduct red nucleus substansia nigra crus cerebri and cranial nerve 3 nucleus and fibers are found in the midbrain
• superior cerebellar peduncle locus ceruleus 4th ventricle middle cerebellar peduncle corticospinal and corticobulbar tracts cranial nerve 5 are found in the pons
• inferior cerebellar peduncle dorsal motor nucleus cranial nerves 12 10 inferior olivary complex nucleu ambigus nucleus tractus solitarius are found in the medulla
• medial leminiscus is found at all levels
• medial longitudinal fasiculus is found in medulla and pons
