Motor (Muscle fibres (Slow (Slower and weaker, Able to sustain contraction…

- - - - Connect each skeletal muscle to the bone
      - Protective function
    - - Embedded in muscle tissue
      - Respond to changes in muscle length
- - - - Send impulses from the CNS to our limbs and organs
    - - Receive impulses from sensory organs and transmit to CNS
  - - - Posture
    - - Eye movement reflexes
    - - Intended to protect the body from damaging stimuli
      - Polysynaptic
- - - - Transmit information from the CNS to the muscles
      - Stimulate movement
- - - - These synapse on distal muscles of the wrist, hands, fingers and toes
  - - - These synapse on motor neurons that project to the arms and legs
  - - - Via four brain structures
        
        Tectum
        
        Vestibular nucleus
        
        Reticular formation
        
        Motor nuclei
- - - - The visual system
      - The auditory system
      - The somatosensory system
    - - Disorder of voluntary movement that is not attributable to a simple motor deficit or to any deficit in comprehension or motivation
      - Patients have difficulty making specific movements when they are requested to do so
      - Can readily perform the same movements under natural conditions when they are not thinking about what they are doing
      - Caused by unilateral damage to the left posterior parietal cortex or its connections
      - Ideomotor apraxia
        
        Simple motor activity in response to verbal command
      - Ideational apraxia
        
        Respond to stimuli
        
        Sequence of actions
    - - Disturbance of a patients ability to respond to stimuli on the side of the body opposite to the side of a brain lesion in the absence of simple sensory or motor deficits
  - - - Inability to distinguish a true memory from a false one
- - - - Measure time
        
        Feeds calculation to the PMC
      - Ensures that when one set of muscles initiates movement, another can act as a brake.
    - - Loss of ability to maintain proper muscle coordniation
  - - - Cortical input from various cortical areas and transmit back via the thalamus
