The Human Brain : From Neurone to Nervous System


  1. Sensory Receptors are nerve endings containing transducers that respond to a specific stimulus.
    In the skin there are different modalites of sensation with corresponding sensory receptors, mediating touch, vibration, pain and temperature.

  2. Conscious animals and humans perceive sensations including touch, vibration, temperature and pain. The position and intensity of stimuli are signalled by the activity of individual sensory axons, and the nature of the stimulus, such as innocuous or noxious, is signalled by separate classes of afferent ending.

  3. Innocuous sensations are mediated by afferents with encapsulated sensory endings, while noxious sensations are mediated by small diameter axons with free nerve endings.
