Magnified 28x, this 2005 scanning electron micrograph (SEM) depicted the head region of a roach found deceased in a Decatur, Georgia home. Each of the two antennae was fractured off where the first segment, known as the 'scape', joined the 'pedicle', or the second antennal segment. The antenna on the right is situated in such a way that its interior, or 'lumen', is made visible, and appears to be hollow. When it was alive, the roaches blood, known as 'hemolymph', and some of the antennal soft tissues such as musculature and sensory innervation, would have filled these now hollow, tube-like structures.
