acron

It asserts that the insect head consists of the acron plus six segments.

The attribution to Acron, however, is not found before the 15th century, and is doubtful.

The eyes are mounted on the acron.

As a result, the idea of the arthropods having inherited a preoral acron from their ancestors seems less likely.

The Protocerebrum represents the fused ganglia of the acron and the preantennal segment.

Fragments of Acron's writing may also appear in Pomponius Porphyrion.

Such a situation has led Matsuda (1965) to claim that in most insects the head comprises an acron and only five cephalic segments.

The head is composed of a presegmental acron that usually bears eyes (absent in Protura and Diplura), followed by six segments, all closely fused together, with the following appendages:

There is, however, every reason to believe that the insect head arose by the coalescence of a number of body segments and a non-segmental anteriorly-placed acron homologous with the Annelid prostomium.

None of Acron's works are now extant, though he wrote several in the Doric dialect on medical and physical subjects, of which the titles are preserved by the Suda and Eudocia.
