Document Summary
Sensory systems of particular animals have restricted ranges of responsiveness. Study questions: specialized body components, collectively called sensory receptor organs, are sensitive to energies of various sorts that come into contact with the body. The job of these organs is to convert environmental energy into electrical signals: here is great diversity in receptor organs across species, reflecting the particular ecology of each species. For example, some migratory animals can sense magnetic fields, some snakes have detectors adapted to perceiving infrared radiation, and some species of fish are sensitive to electricity: humans do not hear sounds above 20,000 hz. The type of sound above this range is: complete the following statements about hearing in different classes of animals (based on ultrasonic. Study questions: the idea that each sense has its own unique receptors and independent neural channels is called the doctrine of specific nerve energies. For instance, activity in the touch receptor pathway can be perceived as touch only.
