Central nervous system (Spinal cord (cervical and lumbar enlargements…

- - - - control over voluntary movements
        
        pyramidal cells (neurons)
  - - - consciously aware of these sensation
        
        Skin, muscle, joints, touch, temperature, pain.
        
        Proprioception
  - - - controls motor movements of speech.
  - - - understands speech and able to name objects and read words.
  - - - Short
        
        Connect parts of the same hemisphere, all white matter.
    - - one hemisphere to the other
        
        corpus callosum
    - - Longest of all tracts, verdictly
        
        Connect the cortex to more caudal parts of CNS
- - - - all sensory into on the way to the cortex gives through except olfaction. Relay station there can be amplification or tone down the signal.
  - - - controls autonomic nervous system with the help of gray matter in brain stem.
        
        regulate hunger, thirst, sleep/wake cycle.
        
        controls endocrine system, emotional responses,motivational behavior and formation of memory.
- - - - corpora quadrigemina are the four bumps
        
        superior colliculi involved in visual reflexion
        
        Inferior colliculi involved in auditory reflexion.
  - - - connects cerebellum to cerebral cortex
    - - involved with autonomic behavior
  - - - heart, blood pressure and breathing rate.
    - - pyramids
        
        cortex of precentral gyrus motor output through pyramidal tracts.
      - decussation of pyramids
        
        crossing from one side to other all parts of brain stem
      - cranial nerve nuclei
        
        cranial nerve connects with brain. Ten out of twelve connect except olfactory or optic.
      - sensory tracts
        
        signals sensory and motor tracts
- - - - superior
        
        midbrain to cerebral cortex (efferent)
      - middle
        
        pons ( efferernt)
      - Inferior
        
        medulla oblongata afferent pathway proprioception and equilibrium
- - - - tough, dense fibrous connective tissue
    - - (Spider mother) Between dura and pia
      - subarachnoid space filled with CSF and blood vessels
    - - thin fibrous tissue that can not be seen, transparent, layer of tissue that is very vascular and capillary rich.
    - - open space that can be open if separation of arachnoid mater from the dura matar.
    - - filled with adipose
