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.
