Document Summary
Hindbrain, midbrain and forebrain (most important of the three) The hindbrain: one of the three bulges of the embryo"s neural tube; evolutionarily the structures in the hindbrain are most primitive. Medulla oblongata: transmits info from the spinal cord to the brain and regulates life support functions like respiration, breathing, etc. The pons: neural relay station, balance of the body, visual and auditory info processing. Cerebellum: muscular activity, most primitive, governs balance and involved in motor behavior and coordination. Brain stem: contains the medulla and pons of the hindbrain, as well as the midbrain and the certain structures of the forebrain. Midbrain: involved in relaying info between other brain regions. Reticular formation: keep us awake and aware, sudden arousal needed to respond. Forebrain: has sulcus (a prominent shallow groove on the surface of the brain) and gyrus (convolution or ridge of the brain). The prefrontal cortex of the frontal lobe shows the longest period of maturation and the first to age.
