Central nervous system (cerebrum (post central gyri (Description: Location…

- - - - Function: visceral control center
        
        ventral body cavity
      - It is composed of several nuclei
  - - - Forms part of the roof of the third ventricle and consitss of one tiny group of brain nuclei and and unpaired knob called the Pineal gland
      - Pineal gland
        
        Function: Secretes melatonin
      - The third and most dorsal
  - - - all concious sensory signals to thalamus on the way to the cortex; except olfaction/smell
      - Signals may be amplified or "tones down"
      - Paired Structure; Composed of several nuclei
- - - - Middle cerebellar peduncle
      - Reticular formation nuclei
        
        Involved with autonomic behaviors; keeping you breathing
      - Pyramid tracts run through the pons
  - - - most caudal part of the brain stem, it is continuous with the spinal cord
    - - Reticular formation nuclei:
        
        vasomotor center
        
        description: blood pressure
        
        respiratory center
        
        cardiovascular center
      - Pyramid tract
        
        Only motor
  - - - corpora quadrigemina
        
        where auditory and visual reflexes are integrated by brain nuclei
      - superior colliculi
        
        visual reflexes
      - cerebral peduncles
        
        composed of pyramidal motor tracts
      - Inferior Colliculi
        
        auditory reflexes
- - - - Arbor Vitae; White matter
- - - - Cortex
  - - - Connects parts of the cortex of same hemisphere
      - Not crossing over to the other side of the brain
  - - - axons
- - - - Vascular layer
      - Vascular layer has Capillaries
      - Very thin, right on the cortex
  - - - subarachnoid space + blood vessels
        
        Filled with cerebral spinal fluid
  - - - Filled with cerebral spinal fluid
      - Part of the Brain + Spinal cord
  - - - Periosteal layer - Near bone
      - Meningeal Layer- Deeper
        
        The subdural space - thin layer of fluid
      - Most superficial - tough, dense, fibrous connective tissue
  - - - Deep to the dura mater
      - Part of the Brain + Spinal cord
