CNS (Brain (Cerebrum (Diencephalon (Brainstem -connector -sensory info…

- - - - Precentral Gyrus
        -initiates voluntary movement
        
        Primary motor cortex
        -generate impulses that controls movement
    - - Postcentral Gyrus (lateral parietal lobe)
        -General sensory, skin
        -Propreceptors, joints, muscle, tentons, ligaments
        
        Somatosensory Cortex
        -conscious awareness
    - - Thalamus
        -collection of nuclei
        -all sensory signals to cortex relay through thalamus, except olfactory
      - Hypothalamus
        -collection of nuclei
        -automatically control/regulate visceral motor, body temp, hunger and thirst, sleep/wake cycle, endocrine system, motivation for sex/food
      - Epithalamus
        -secretes for hormone melatonin
      - Brainstem
        -connector
        -sensory info travels through
        
        Midbrain
        -fight for flight behavior
        
        Pons
        -relays information form the cerebellum to the rest of the brain
        
        Medulla Oblongata
        -pyramidal tract and reticular formation nuclei
        -cardiac center, regulates heart rate, force of contraction
        -valomotor center, regulates blood vessels, dilate/contraction bp
        -respiratory center, breath rate
        
        Pyramidal tracts
        -motor tract
        -carry signal from cortex to spinal cord back and forward
        
        Reticular Formation Nuclei
        -gray matter
        -involved with automatic behavior
        
        Cerebellum
        
        Cerebral Peduncles
        -tracts that carry signals from cortex to spinal cord.
        -voluntary movement
        
        Superior Colliculi
        -visual reflex
        
        Inferior Colliculi
        -auditory
  - - - Tight Junction
        -between endothelial cells
        -keep harmful substances our of brain tissue
- - - - Posterior root ganglion
        -collection of sensory neuron cell bodies
