| Which of all living things have the most highly developed responses to stimuli? | Animals |
| Almost all _____________ have sense organs. | Animals |
| Where are the receptors located in animals? | the sense organs |
| What do the sense organs contain? | receptor cells |
| What do receptor cells do? | capture a particular type of stimulus and send a signal to the coordination systems which interpret them as a sensations |
| Name a type of stimulus | Light, vibrations, etc. |
| Name a sensation | an image, a sound, a smell, a taste |
| What are the photoreceptor organs of an animal? | The eyes |
| Receptor cells which capture light and permit light are located in what receptor organ? | The eyes |
| Where are eyes normally located on an animal? | On the head |
| What type of eyes do many invertebrates have? | simple eyes |
| What type of eyes do arthropods have? | compound eyes |
| What type of eyes do cephalopods have? | camera type eyes |
| These type of eyes only detect light, the animal perceives it and moves toward it. | simple eyes |
| These type of eyes are composed of thousands of units or ommatidia | compound eyes |
| What type of eyes are similar to that of a camera and provide clear images of their surroundings? | camera type eyes |
| What types of living things have camera-type eyes? | some invertebrates, such as the cephalopods, and almost all vertabrates) |
| Name a type of mechanoreceptor organ | hearingn organs, balance organs, the lateral line of fish, the skin, etc. |
| What type of organs of animals have receptor cells which capture substances which are in the air, water and foods. They provide two closely related senses: smell and taste. | Chemoreceptor organs |
| What are the two senses of the chemoreceptor organs? | smell and taste |
| Where are the chemoreceptor organs located? | on the head, near the mouth |
| Where are the chemoreceptor organs located in the arthropods? | on the antennae |
| Where are the chemoreceptor organs located in vertebrates? | in the nostrils or on the tongue. |
| Orfices in the body which capture the vibrations in the air or water and transmit them to receptor cells | hearing organs |
| These contain numerous receptors for substances inthe air. | antennae |
| a channel with receptor cells capable of detecting vibrations and movements in the water | the lateral line of fish |
| Tongue makes up what type of chemoreceptor organ | smell and taste organs |
