6th Science Chapter D1
Name ___________________________________
1. What is the system that checks your body’s condition, causing hormones to be released when necessary?
Endocrine System
2. A neuron is a nerve cell.
3. The gap or space between the axon of one neuron and the dendrite of another is called a synapse.
4. The part of the brain that allows you to think is the cerebrum.
5. The sense of smell is closely linked to the sense of taste.
6. The cones are the part of the eye that is sensitive to color.
7. The type of nerve cells that allows you to see, hear, and smell are sensory receptors.
8. The layer of light receptors at the back of the eye is called the retina.
9. The body’s boss is the brain.
10. The part of the neuron that collects information from other neurons is called the dendrite.
11. The system that exchanges messages with your internal organs is the nervous system.
12. The long tail-like part on the neuron is the axon.
13. Some examples of reflexes are Flinching or dodging, pulling away from something hot or sharp,
sneezing, coughing
14. The part of the central nervous system that is skipped in a reflex is the brain.
15. What part of the brain controls breathing? Brain Stem
16. What is the sense organ for vision? Eyes
smell? Nose
hearing? Ears
17. The body gets a lot of energy from sugar or Glucose
18. What organ releases insulin? pancreas.
19. What is the part of the neuron that collects information from other neurons? dendrite
20. How is your nervous system like a two-lane highway? Information is traveling both to and from the
brain just like cars are traveling to and from the city.
21. How is a message sent from one neuron to another? The dendrites receive messages from other nerve
cells. Then an electrical charge forms and is sent through the cell body and axon. When it gets to
the end of the axon, chemical messengers are released into the synapse and they attach to the next
neuron’s dendrites. This process repeats itself.
