The endocuticle of beetles formed after adult eclosion is brick-like, Balken cuticle with unidirectional stacks of chitin. The cuticle is thick in areas such as the pronotum, leg cuticle, …

Mar 4, 2017 · Using light, scanning, and transmission microscopy, the present study examined the structure and formation of the cuticle and underlying epithelium in five chiton species collected …

The arthropod integument consists of the cuticle and the underlying epidermis (Figures 1, 2) and the cuticle serves as both the outer covering of the animal and as the skeleton. The cuticle is …

Chitons (Mollusca; Polyplacophora) have thousands of sensory organs, termed aesthetes, embedded in their eight dorsal shell plates. Aesthetes are thought to be sensitive to light, as …

Oct 15, 2024 · The combination of the ventral scales and cuticle, along with the regular arrangement of ventral scales, may allow chitons to simultaneously address complex and …

Jun 1, 2022 · The cuticle proteins, together with chitin, assemble in the molting stage and degrades during spinning and metamorphosis. We conclude that these cuticle proteins can …

Jan 1, 2022 · Chitin, a linear structural polysaccharide is a major constituent of insect procuticle. Chitin is embedded in a complex matrix of proteins, which contributes significantly to the …

Chitin contributes to the rigidity of the insect cuticle and serves as an attachment matrix for other cuticular proteins. Deficiency of chitin results in abnormal embryos, cuticular structural defects …

A homogenous cuticle, about 100 μm thick, covers the dorsal epidermis of the perinotum of Mopalia muscosa (Figs. 1, 25). The presence of chitin in this layer and in hairs was …

At first, only the tips of the spicules lie within the cuticle, but by two days after settlement the spicules are completely extruded and enveloped by the cuticle. The cuticle is thick dorsally …
