Document Summary
Overview: examine what parts of the brain control our behavior, intelligence, memory, development of the brain, how the brain is protected, structure of the brain, cranial nerves, clinical applications. Brain development: neural tube, primary brain vesicles, secondary brain vesicles, adult structures. Four major parts of the brain: adult brain consists of four major parts, brain stem, medulla oblongata, pons and midbrain, cerebellum, diencephalon, thalamus and hypothalamus, cerebrum. Protective coverings of the brain: cranium and cranial meninges, cerebrospinal fluid, blood brain barrier. Clinical connection: hydrocephalus head is enlarged; usually caused by the inability to reabsorb the csf. Blood brain barrier: allows oxygen and glucose into brain, protects from harmful substances and pathogens, proteins and antibiotics can not cross bbb, oxygen, carbon dioxide, anesthetic drugs, and alcohol can cross. Clinical connections: cerebrovascular accident (cva) 2 types, blood to brain is blocked by some blood clot, transient ischemic attack (tia)
