  sensations receptors
• What are some sensations that are acute or temporary?

  • Slow Adapting Receptors
  sensations receptors
• What are fast adapting receptors called?

  Phasic receptors
  biology sensory
• Do you always sense the temperature in your house?

  No, we often become unaware of constant stimuli.
  biology sensation
• Are your thermoreceptor sensations active in your house?

  No, they adapt to the constant temperature.
  biology thermoreception
• What happens when you go outside on a hot day?

  You feel the change in temperature immediately.
  biology environment
• What is it called when sensation decreases due to constant stimulus?

  This is known as adaptation.
  biology sensation
• What is meant by background sensation?

  It's the constant input from stimuli that we often ignore.
