| The cortex is capable of storing and retrieving information from both short-term and long-term | memory |
| The brain interprets the meaning of the sounds we hear as music, speech, noise, etc. Which ear structures are responsible for the amplification and transfer of sound from the external ear to the inner ear? | The ossicles |

| Which of the following is not a characteristic of the endocrine system? | Chemical messenger travels a short distance. |
