Human Sensory Organs starts at 7 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Human Sensory Organs. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
Describe the difference between general and special senses in humans.
Describe the function of the rods and cones in the human eye.
Describe the pathway of sound from the outer ear to the brain.
Describe the process of accommodation in the human eye.
Describe the role of chemoreceptors in the human sensory system.
Explain how the human nose detects different odors.
Explain how the semicircular canals help maintain balance.
Explain the role of mechanoreceptors in the skin.
Explain why a person with a cold may have a reduced sense of taste.
Explain why humans have a blind spot in each eye.
Name the three bones found in the middle ear.
The retina is a part of which human sensory organ?
The sense of balance is primarily maintained by which part of the ear?
Which type of photoreceptor cell is responsible for color vision?
A person is exposed to a constant, strong odor for several minutes and then stops noticing it. What is the term for this phenomenon, and what is its biological significance?
Context: A person is born with a genetic mutation that causes the absence of cone cells in the retina. Question: What effect would this have on the person's vision, and why?
Describe the process by which photoreceptor cells in the retina convert light into electrical signals that can be interpreted by the brain.
Describe the role of the thalamus in processing sensory information from the sensory organs.
Explain how lateral inhibition in the sensory pathways enhances the perception of contrast in touch or vision.
Explain why damage to the parietal lobe of the brain can affect the sense of touch.
