Central Nervous System (Main functions (Division of nervous system…

- - - - Cerebral
        
        Little feet of cerebrum
      - Pons
        
        Connects spinal cord with brain response to sound & visual stimuli
  - - - Outermost layer
    - - Many blood vessels and they are attached to perostum
    - - Meninges
    - - Spider web line collage and elastic fiber thin membrane that lacks
    - - Filled with cerebrum spinal fluid
- - - - Somatic nervous system
  - - - Sympathetic nervous system “fight or fight”
      - Emergency or non-normal situations
- - - - Eliminated axon conducts an impulse over its entire surface
      - Saltatory conduction myelinated axon from mode next much faster
- - - - Supply moje in spearheaded to axons in the DNS
    - - Flattened cells found in the regrowth of peripheral axons
- - - - Connects two hemispheres cerebrum is divided into lives
    - - Central sulcus divides frontal & parietal lobes
    - - Separates brain into right and left cerebral hemispheres
    - - Dark outer area consists cell bodies of 75% of all neurons in the nervous system
    - - Separates cerebrum and cerebellum
  - - - Muscle movement for speech
    - - Concerned with more complex integrative functions such as memory emotions reasoning will judgement and intelligence language comprehension
    - - In front of the central sulcus of specific muscles groups of the opposite of the body
  - - - Little brain
    - - Convolutions grooves
    - - Narrow worm shaped structure in between both sides of the cerebellum
  - - - Cerebrum
        
        Largest portion
      - Diencephalon
        
        Superior to brain stem surrounded by cerebrum
      - Medulla oblongata
        
        Pond and midbrain
      - Hypothalamus
        
        Brain stem
- - - - Impulses towards CNS specialized receptors ends at tips of dendrites of the dentries
    - - Multipolar neurons in CNS that form links between other neurons
