|
Complement of nervous tissue (neurones, nerves, receptors and support cells) serving to detect, relay and coordinate information about an animal`s internal and external environments and to initiate and integrate its effector responses and activities. |

WBbt:0005735
|
a single, H-shaped cell which lies just above the anus and connects the roof of the anal canal to the dorsal bodywall; its contractions act to increase the size of the anal opening by lifting the roof of the rectum and hence facilitate expulsion of intestinal contents. |
