Cerebrospinal Fluid Function Location Choroid plexus – Circulation

Circulation of CSF Lateral Ventricles – In cerebrum – Interventricular foramen

Circulation of CSF Third Ventricles – Diencephalon – Cerebral aqueduct = Mesencephalic aqueduct

Circulation of CSF Fourth ventricle Ventral to cerebellum

BRAIN STEM Medulla Oblongata Location Ascending/descending tracts Vital Reflexes – Cardiac, Breathing, Vasomotor Center – Misc. centers Reticular formation (RAS)

BRAIN STEM Pons Location Function

BRAIN STEM Mesencephalon (midbrain) Location Cerebral Peduncles Corpora Quadrigemina – Superior colliculi – Inferior colliculi

Diencephalon Thalamus – Location – Function Hypothalamus – Location – Function
