- - - - three paired structures
        
        hypothalamus
        
        center for emotional responce autonomic control center
        
        functions involve blood preassure , body temp, water balance.
        
        hormones, oxyonic anti diuretic.
        
        epithalamus
        
        endocrine glands(pineal gland)
        
        melatonin
        
        thalamus: gateway to the cerebral cortex
      - brain stem
        
        oldest part of the brain.
        
        cardiovascular center
        
        adjusts force and heart rate of eheart and contraction and blood vesssel size for blood preassure
        
        respiratoryncenters
        
        generate respiratory rhythm and control
        
        vomiting , hiccupping, swallowing, coughing, sneezing
        
        cerebellum
        
        skeletal musle contraction
        
        puzzle solving, word association,
- - - - sends mesages to or from the CNS
    - - command center
      - consists of the brain and the spinal cord
      - visceral sensation
        
        internal organs
  - - - somatic sensation
      - or internal organs
        
        visceral sensation
- - - - the skull and the vertebrae and ligaments of the psine
      - the meninges
        
        three membranes that cover and protect the brin, spinal cord. and blood vessles, the outer dura mater ) is esentially tough in order to protect the cns
      - cerbrospinal fulid (cfs)
- - - - collections of neurons outside the the CNS
  - - - carry signals away fro the cell body
      - have terminals that store and relase messanges substances.
      - myeli sheath: protien lipoid around axons
      - supported by myelin
        
        white brain matter
      - non-myelinated
        
        grey brian matter
  - - - SAM
        
        Motor (efferent )neurons
        
        carry impulses away from the cns to muscles and glands
        
        muscle memoorty
        
        association (connecting ) neurons
        
        link sensory and motor neurons
        
        judgment reasoning persistance and conscience.
        
        sensory (afferent) neurons
        
        tramsit imulses from senssory receptors twords the CNS
        
        skin muscles joints and internal organs such as stomacj and bladder
      - ACE
