9 THE DIENCEPHALON Thalamus ☆ All sensory info (except smell) is relayed through & then sent to appropriate areas of brain for response
10 THE DIENCEPHALON Hypothalamus ☆ Primary link between NS & endocrine – pituitary releases hormones☆ Regulates moods, thirst, appetite, waking vs sleep☆ Regulates body temp & water balance☆ Reg. & coordinates autonomic – digestion & urination
11 THE BRAIN STEM 1. Midbrain: ☆ Maintains alertness 2. Pons: ☆ Regulates respiration rate3. Medulla Oblongata:☆ Connects brain to spinal cord☆ Regulates breathing rhythm, ♡ rate, blood flow☆ Reflexes: vomiting, sneezing, hiccupping & swallowingAll information to and from our body passes through the brain stem on the way to or from the brain. Like the frontal and temporal lobes, the brain stem is located in an area near bony protrusions making it vulnerable to damage during trauma.
12 THE CEREBELLUM☆ Coordinates subconscious skeletal muscle – maintains balance & postureEx: moving an object☆ Damage – trauma, stroke or drugs (alcohol) = ataxia2nd Largest Region
13 THE LIMBIC SYSTEM☆ A functional system not anatomical – parts of cerebrum, hypothalamus & brain stem☆ Emotion centers, memory, links conscious thoughts to unconscious functions
