Brainstem Oldest evolutionarily Includes mid and hindbrain Medulla oblongata & pons which control heart rate, vessels, digestion & respiration Midbrain connects hind and forebrain and is used for eye reflexes.

Cerebellum Third part of hind brain Controls fine motor coordination Large in birds

Forebrain or Cerebrum Cerebrum Thought Speech Motor integration Diencephalon Thalamus (switching center) Hypothalamus (homeostasis)

A Cerebrum, Cerebrum B Cerebellum, Cerebellum C Mid-brain, Mesencephalon D Pons, Pons E Medulla oblongata, Medulla oblongata The latter is continuous with the spinal cord through the foramen magnum.
