sensory receptors - respond to stimuli, Sensation - action potentials …

- - - - tactile corpuscles - fine touch
      - lammellated corpuscles - heavy pressure
      - free nerve endings - itching
      - proprioceptors - info to CNS about position
        
        lamellated corpuscles - pressure in joints
        
        muscles spindles - stretch in skeletal muscles
        
        golgi tendon organs - stretch in tendons
  - - - proprioceptive sense - muscles, tendons, joints
      - exteroceptive senses - touch, pressure, temp, pain
      - interoceptive senses - blood pressure
    - - types (know the anatomy)
        
        taste - taste receptors (chemoreceptors) (gustation is the sense of taste) (taste sensations: sweet, sour, salty, bitter, umami)
        
        hearing and equilibrium - (tympanic reflex muscles contract to prevent damage) (3 sections: outer, middle, inner) (know the anatomy and how it works)
        
        Static equilibrium - head when body is not moving. Dynamic equilibrium - senses rotation of head and body
        
        smell - olfactory receptors (chemoreceptors) respond to chemicals dissolved in liquids
