10 Chilopoda – Endocrine system
2011Studies on structure and function of the endocrine system, and the hormonal control on moulting and gametogenesis, are essentially limited to anamorphic and adult stages of Lithobius forficatus . The moulting cycle of adult L. forficatus is divided into three phases: a post-ecdysial period (about 10 d), an intermolt period (about 20 d) and a pre ...

Centipedes are terrestrial, tracheate arthropods. Spiracles occur on many or most trunk segments, but never on the forcipular segment or the last leg-bearing segment and genital segments. The size of the spiracles increases up to the fourth long tergite covering leg-bearing segments 7-9, to decrease thereafter.

The nervous system of chilopods is divided into the central nervous system, composed of the brain and ventral nerve cord, and the peripheral nervous system with its projecting nerves. The central nervous system (brain or syncerebrum) is divided into the proto-, deuto-, and tritocerebrum.

6 Chilopoda – Digestive system
2011The alimentary canal of centipedes is a muscular tube for unidirectional passage of food from the mouth, which is located in the depth of a preoral chamber, towards the anus at the posterior end of the body. The main digestion and absorption of nutrients occur in the midgut, which produces chitinous peritrophic membranes enveloping the food.

3 Chilopoda – General morphology
2011The body of centipedes is elongate to filiform, obviously segmented, and often flattened. Scutigeromorphs and lithobiomorphs and quite fragile, due to the softness of their integuments and the ease with which their appendages are detached from the body. The body of the centipede is distinctly articulated into head and trunk.

The lightly sclerotised cuticle of chilopods, coupled with their predominantly litter and soil-dwelling habits, set constraints on their fossilisation potential. In spite of this, of the five extant chilopod orders, two (Scutigeromorpha and Scolopendromorpha) have a fossil record extending back to the Palaeozoic, and an extinct order in the Middle ...

5 Chilopoda – Musculature and locomotion
2011This chapter analyzes Manton's comparative morpho-functional studies of centipede locomotion. Following earlier structural investigations in light microscopy centipede muscles - together with sperm cells - were the object of the oldest ultrastructural studies performed on Chilopoda. Centipedes are a choice group for the study of locomotion.
