central nervous system (cerebrum (lobes (temporal lobe (located in the…

- - - - location of primary motor cortex
    - - location of primary somatic sensory cortex
  - - - located in the bottom area of the brain the temporal lobe is mostly associated with language and sound
    - - located in the middle section the parietal lobe is mostly associated with processing tactile sensory information.
    - - located in the front of the brain the frontal lobe is most associated with reasoning and motor skills.
    - - located in the back portion the occipital lobe is mostly associated with visual information and stimuli
  - - - cross from one cerebral hemisphere to another
      - enable communication between the left and right side of the cerebrum
    - - connect different regions within the same hemisphere of the brain
    - - extend vertically between higher and lower brain areas and spinal cord
      - carry information between the cerebrum and the rest of the body
- - - - composed of pyramid motor tracts to cerebral cortex that then goes to the spinal cord
    - - four bumps
      - superior colliculi
        
        involved with visual reflexes
      - inferior calliculi
        
        involved with auditory reflexes
  - - - "pyramids" located at the top of the M.O. along the bulged area
      - decussation of pyramids
        
        the crossing over of motor tracks on the bottom of the M.O.
    - - have a cardiovascular center
      - vasomotor center
        
        blood pressure (keeping it normal)
      - respiratory center
  - - - cluster of cell bodies
        
        involved with autonomic behavior
- - - - with other parts of the brain somatic and coordinate body movement
  - - - pons to cerebellum
        
        efferent connection
    - - connection from spinal cord to M.O. to cerebellum
        
        afferent connection
    - - coordinate movement
        
        brain to cerebellum
        
        efferent connection
- - - - allow motor neurons to exit the spinal cord
- - - - spider mother
      - below it has the subarachnoid space and blood vessels filled with cerebrospinal fluid
    - - gentle mother
      - very thin vascular layer
      - right on cortex
      - capillaries in the vascular layer
    - - tough mother
      - tough dense fibrous C.T.
      - made of two layers
        
        periosteal layer
        
        near bone
        
        meningeal layer
        
        deeper layer
      - subdural space
        
        filled with cerebrospinal fluid
