Sensory reception

Cards (8)

  • Effectors are a range of cells/tissues/organs that carry out a response
  • Stimuli are detectable changes in the internal or external environment
  • Receptors are cells/organs that detect specific stimuli
  • Kinesis is a random non-directional response to an unpleasant stimuli
  • A coordinator is an intermediary between a receptor and effectors which formulates a suitable response to a stimulus
  • Taxis is a directional response to a stimuli
  • Basic sequence of a response arc
    stimulus -> receptor -> coordinator -> effector -> response
  • The direction of taxis is determined by the direction of the stimuli. Positive taxis is towards a stimulus, negative taxis is away from a stimulus
