      - Baroreceptors: blood pressure receptor.
    - - Exteroceptors: Located on our skin.
      - interoceptors: located in our internal organs.
      - Proprioceptor: Located in muscle tissue.
  - - - Cornea: transparent part of the eye that lets light in.
        
        lens: A thick transparent disc that allows light to be focused
        
        Retina: the back of the eye which contains photoreceptors.
        
        Optic nerve (Cranial nerve II): the place at which the visual signal turns into a neural (electrical) signal.
