Cells programmed to develop as cartilage would, for example, migrate only to the head region.

They said rodents were distinguished by their entire head region.

For negative streamers, free electrons are accelerated from the channel to the head region.

The head region is clearly demarcated, has eight eyes and a few setae.

The prosoma has a wide and high head region.

In this study, however, the influence of surrounding forms, like the head region of a predator, was not tested.

In other cases the parasite is attached in the head region of to the trunk.

In addition, they have a head region that contains concentrated sense organs and nervous tissue (brain).

This process eventually produces a head region with sensory organs.

The conodonts can be seen in the head region, set back a little and slightly scattered (see figure).
