- - - - sex
      - food
  - - - nucleus
      - pineal gland
        
        secretes melatonin
- - - - Efferent
      - cranial nerves that attach to the pons
    - - Afferent
      - connect medula to cerebellum dorsaly
      - need proprioception signals
    - - Efferent
      - connect the midbrain to the cerebellum
- - - - take us from one hemisphere to the next
    - - Longest of the 3 tracts
      - descends from cerebral cortex
      - Ascends to cortex from lower regions
    - - connects part of the same heisphere
- - - - composed of pyramidal motor tracts
      - from cerebrum to spinal cord
    - - Superior Colliculi
        
        involved in visual reflexes
      - Inferior Colliculi
        
        involved in auditory reflexes
  - - - connect cerebellum to cerebral cortex
    - - involved with autonomic behaviors
  - - - Cortex of precentral gyrus
      - motor output through pyramidal tracts
    - - crossing from one side to the other
    - - place where cranial nerves connect to the brain
      - olfactory and optic nerves do not connect
    - - ascending tracts
        
        carry sensory info to the brain
      - descending tracts
        
        carry motor instructions to the effectors of the body
- - - - Filled with C.S.F and blood vessels
    - - Fibrous C.T.
      - very vascular - capillary rich
    - - Tough dense fibrous C.T
      - perosteal portion
      - meningeal portion
