Document Summary
Cns: made up of brain, brain stem and spinal cord. Pns: encompasses somatic nervous system, autonomic nervous system goes out from and comes into the cns. Nerves (peripheral nervous system) do not stay within the cns: innervate organs, muscles, joints and skin. Innervates muscles of face head and neck: cns from brain stem to innervate those muscles. Sensory nerves: hearing, vision, taste, smell (head and neck information) Cranial nerves: motor and sensory spinal cranial nerve innervate organs, laryngeal areas. Parasympathetic system: back to normal levels after sympathetic activation (reduces heart rate, tells sweat glands to turn off) Forebrain: consist of cerebral hemispheres, basal ganglia and limbic lobe. Central nervous system starts off as hollow tube: contains cerebrospinal fluid. 3 bumps: forebrain, midbrain, hindbrain ( hollow tube: ventricular system) Elaborate and complex structure: neural complexity and connectivity. Brain consumes 20% of oxygen and glucose in body. White matter: extends from cortex and goes to other places.
