Central Nervous system (Spinal Cord (Filum terminale (Connective tissue,…

- - - - efferent
      - connect pons with our cerebellum and cerebrum
    - - afferent
      - one direction from medulla oblangata to cerebellum
      - proprioception --> equilibrium
    - - efferent
      - connects midbrain to the cerebellum and cerebral cortex
- - - - Secretes melatonin (prepares us for sleep)
- - - - Connects cerebellum to cerebral cortex
    - - involved with autonomic behaviors
  - - - Superior colliculi
        
        involved in visual reflexes
      - Inferior colliculi
        
        auditory reflexes
    - - Composed of pyramidal motor tract from cerebrum to spinal cord
- - - - Lots of blood vessels
      - Subarachnoid space
        
        Filled with cerebral fluid
    - - Fibrous C.T
      - on the surface of the cerebellum
      - very vascular (capilary rich)
    - - tough
      - Dense fibrous C.T
      - Perosteal layer
      - Meningeal layer (deeper)
      - subdural space
        
        filled with liquid
- - - - Language comprehension
      - Emotional response
      - Recognition (objects, words, faces)
      - Memory
      - Auditory and olfactory cortex
    - - Visual cortex
    - - Awarness
        
        ex: sounds, body parts, objects
      - Conscious awarenes
        
        Ex: general somatic sensations (touch, temperature)
      - Sensory information
    - - Gustation cortex
      - General visceral sensations (stretch, discomfort)
    - - Thinking
      - Planing
      - Decision making
      - initiating voluntary movement
      - Memory
  - - - Voluntary movement
      - Pyramidal cell (neurons)
      - Primary motor cortex
    - - Primary somatosensory cortex
        
        Muscle
        
        Propriception
        
        Joints
        
        Extremidies
        
        Skin
      - Conscious awareness of sensations
  - - - Understanding of speech
      - Ability to name objects
      - Left hemisphere
      - Ability to read words
    - - Left anterior hemisphere
      - Controls motor movements of speech
  - - - Connects parts from one hemisphere to another
        "corpus collosum"
    - - (ascending) sensory information comes from PNS and spinal cord to the cortex
      - (descending) signals go from cortex down to spinal cord and PNS
      - Runs vertically
      - Longest
    - - Connects parts of same hemisphere
