Phylum Arthropoda (specifics) ~ - tagmosis: fusion of metameric body plan into functional units - growth by molding termed ecdysis - functional cilia absent (except sperm in some) - cuticle forms a rigid exoskeleton Class Hexapoda (specifics) ~ - ph. Arthropoda, sub uniramia - specialized mouth parts - metamorphosis — hemimetabllous dvlpmt - eggs > nymphs > adults - juvenile resembles adults - ie crickets, grasshoppers — homometabolous - eggs > larvae > pupa ...

Insect body is differentiated into three distinct regions called head, thorax and abdomen (grouping of body segments into distinct regions is known as tagmosis and the body regions are called as tagmata).

Se explican los procesos de tagmosis y metamerización, indicando la diferencia entre la segmentación homómera y heterómera. Respecto al exoesqueleto, se define, se indica su principal componente y se explica el proceso de muda y de esclerificación. Finalmente, se hace referencia a los principales apéndices articulados de los artrópodos.
