  • 2. 

    What is the primary organ of taste?

    • Tongue

    • Nose

    • Ear

    • Skin

    Correct Answer
    A. Tongue
    Explanation
    The tongue is the primary organ responsible for the sense of taste. It is covered in small bumps called taste buds, which contain sensory receptors that respond to chemical molecules dissolved in the saliva. Different areas of the tongue are more sensitive to specific tastes, such as sweet, sour, salty, bitter, and umami, though this distribution is more nuanced than the traditional tongue map suggests.

    What is responsible for detecting odors?

    • Taste buds

    • Olfactory receptors

    • Hair cells

    • Salivary glands

    Correct Answer
    A. Olfactory receptors
    Explanation
    Olfactory receptors are specialized cells located in the olfactory epithelium in the nose. They detect odor molecules inhaled through the nose, initiating a signal transduction pathway that sends information to the brain, where it is interpreted as different smells.

    What sense involves tactile receptors?

    • Smell

    • Taste

    • Touch

    • Sight

    Correct Answer
    A. Touch
    Explanation
    The sense of touch is mediated by tactile receptors in the skin, which respond to various stimuli such as pressure, vibration, and texture. These receptors include mechanoreceptors, which detect mechanical changes in the skin, and are crucial for distinguishing objects and textures by touch.

    Which sense can identify chemical substances in food?

    • Sight

    • Smell

    • Hearing

    • Taste

    Correct Answer
    A. Taste
    Explanation
    The sense of taste can identify chemical substances in food through taste receptors on the tongue. These receptors detect chemicals dissolved in saliva and send signals to the brain, which interprets them as different tastes. This sense helps in recognizing safe and nutritious foods versus harmful substances.

    What part of the eye allows you to see color?

    • Lens

    • Retina

    • Iris

    • Cornea

    Correct Answer
    A. Retina
    Explanation
    The retina is the part of the eye that contains photoreceptor cells, including cones, which are responsible for detecting color. There are three types of cone cells, each sensitive to different wavelengths of light (red, green, and blue), which allow us to perceive a wide range of colors. The lens focuses light onto the retina, the iris controls the amount of light entering the eye, and the cornea helps focus light but none of these structures directly contribute to color vision.

    Which sense is most closely linked to memory?

    • Hearing

    • Touch

    • Smell

    • Taste

    Correct Answer
    A. Smell
    Explanation
    The sense of smell is deeply linked to memory due to the brain's anatomy. Olfactory signals are processed in the olfactory bulb, which is closely connected to the amygdala and hippocampus, areas heavily involved in emotion and memory formation. This proximity is why smells often evoke more vivid memories than inputs from other senses.

    Which body part contains the most nerve endings?

    • Tongue

    • Foot

    • Back

    • Hand 

    Correct Answer
    A. Tongue
    Explanation
    The body part that contains the most nerve endings is the tongue. The tongue is densely packed with nerve endings that allow it to detect a wide range of sensations, including taste, temperature, and texture. These nerve endings are primarily concentrated in the taste buds and the surrounding tissue, enabling the tongue to be highly sensitive to different stimuli. This high density of nerve endings makes the tongue one of the most sensitive parts of the human body.

    What type of receptors detect pain?

    • Thermoreceptors

    • Mechanoreceptors

    • Nociceptors

    • Photoreceptors

    Correct Answer
    A. Nociceptors
    Explanation
    Nociceptors are sensory receptors that detect signals from damaged tissue and can perceive pain. They are a type of receptor found throughout the body, including in the skin, joints, and organs. These receptors send signals to the brain when they detect harmful stimuli, which the brain interprets as pain.

  • 10. 

    Through which part of the ear do we perceive sound?

    • Pinna

    • Earlobe

    • Eardrum

    • Cochlea 

    Correct Answer
    A. Eardrum
    Explanation
    Sound waves enter the ear through the outer ear and travel down the ear canal until they reach the eardrum (tympanic membrane). The eardrum vibrates in response to these sound waves. These vibrations are then transmitted through the ossicles (tiny bones in the middle ear) to the cochlea in the inner ear. The eardrum plays a critical role in converting sound waves into mechanical vibrations, which are essential for the hearing process.
