Questions and Answers
  • 1. 

    You smell something delicious baking. What kind of sensory receptors receive that information?

    • A.

      Photoreceptors

    • B.

      Mechanoreceptors

    • C.

      Thermoreceptors

    • D.

      Olfactory receptors

    Correct Answer
    D. Olfactory receptors
    Explanation
    Olfactory receptors are responsible for detecting and receiving information about smells. They are located in the nasal cavity and are specifically designed to detect and respond to different odors in the environment. When you smell something delicious baking, the olfactory receptors in your nose detect the odor molecules in the air and send signals to your brain, allowing you to perceive and recognize the smell.

    Where are most of our sensory receptors located?

    • A.

      Muscles

    • B.

      Skin

    • C.

      Bones

    • D.

      On our internal organs

    Correct Answer
    B. Skin
    Explanation
    Most of our sensory receptors are located in the skin. The skin is the largest organ of the body and is rich in sensory receptors that help us perceive various sensations such as touch, pressure, temperature, and pain. These receptors are responsible for transmitting information from the external environment to our brain, allowing us to interact with and respond to our surroundings.

    What type of sensory receptors process pressure and touch information?

    • A.

      Chemoreceptors

    • B.

      Olfactory receptors

    • C.

      Mechanoreceptors

    • D.

      Photoreceptors

    Correct Answer
    C. Mechanoreceptors
    Explanation
    Mechanoreceptors are sensory receptors that process pressure and touch information. They are specialized to detect mechanical stimuli such as pressure, vibration, and stretching. These receptors are found in the skin, muscles, and other tissues throughout the body, allowing us to perceive sensations of touch, pressure, and texture. Chemoreceptors, olfactory receptors, and photoreceptors, on the other hand, are responsible for detecting chemical, smell, and light stimuli respectively, making them unrelated to the processing of pressure and touch information.

    Your little brother passes gas and it smells AWFUL. Which is the best explanation of how the message gets to the brain?

    • A.

      Olfactory receptors receive scent chemicals, which cause olfactory nerves to send a message to the brain

    • B.

      Mechanoreceptors in the nose receive pressure information and send it through the olfactory nerve to the brain

    • C.

      The olfactory nerve captures sent chemicals and sends them to the olfactory receptors

    • D.

      Olfactory receptors send a message to the mechanoreceptors, which send a message to the photoreceptors in the brain

    Correct Answer
    A. Olfactory receptors receive scent chemicals, which cause olfactory nerves to send a message to the brain
    Explanation
    When your little brother passes gas, scent chemicals are released into the air. These scent chemicals are detected by olfactory receptors in the nose. The olfactory receptors then send a message to the olfactory nerves, which transmit this information to the brain. This allows the brain to perceive and interpret the smell.

  • 5. 

    Which type of sensory receptors are found here that can process taste?

    • A.

      Chemoreceptors

    • B.

      Thermoreceptors

    • C.

      Mechanoreceptors

    • D.

      Photoreceptors

    Correct Answer
    A. Chemoreceptors
    Explanation
    Chemoreceptors are sensory receptors that are responsible for detecting and processing chemical stimuli, including taste. They are found in taste buds located on the tongue and are responsible for transmitting signals to the brain, allowing us to perceive different tastes. Chemoreceptors are specifically designed to detect and respond to various chemicals present in food and beverages, enabling us to experience the sensation of taste.
