tomium's Usage Examples:

The setae are implanted metamerically in accordance with the metamerism of the body, which consists of a prostomium followed by a number of segments.

In Peripatus the prostomium of the Chaetopod-like ancestor is atrophied, but it is possible that two processes on the front of the head (FP) represent in the embryo the dwindled prostomial tentacles.

tp, Velar area of the prostomium.

The body wall consists of an epidermis which secretes a delicate cuticle and is only ciliated in Aeolosoma, and in that genus only on the under surface of the prostomium.

The parapodia of Chaetopoda are never coated with dense chitin, and are, therefore, never converted into jaws; the primitive " head-lobe " or prostomium persists, and frequently carries eyes and sensory tentacles.

The prostomium and the segments generally often bear processes sensory and branchial.

The peristomium has no setae, and the setae generally are hair-like or uncinate, often forming almost complete rings.
