5. A structure that is echo-free appears black.
10. Tissues having several different, uneven echoic characteristics.
12. Further from the point of attachment or origin on the body.
14. Tissues having cystic and solid characteristics.
15. A structure that appears less bright to surrounding tissue.
16. Structures that are comparitively equally echogenic.
19. Acoustic energy that is reflected from a structure back toward the transducer.
20. A structure that is does not contain hollow or gaps.
21. Tissues having similar, even echoic characteristics.

1. The number of cycles per second.
2. A structure that is capable of producing echoes.
3. A structure that appears brighter than surrounding tissue.
4. Away from the head or part of a structure.
6. Divides the body into superior and inferior planes.
7. Closer to the point of attachment or origin on the body.
