In the context of arthropods the integument refers to the outer covering or cuticle, made from chitin. The arthropod strategy is to have the skeleton on the outside, but it performs the same function as internal skeleton in vertrbrates: to provide a structural framework upon which the organism is built, hence of necessity its proverbial rigidity. To some extent the arthropod skin is also a form of armor against predators; for example the pill-bug may roll up to present only the hard exoskeleton and protect the more vulnerable ventral surface. One might also extend this reasoning to the function of limbs, swimmerets, pincers, etc, each with their own requirement of rigidity to be effective.
The integument
After fertilization, the integument of the ovule undergoes significant changes. It typically develops into the seed coat, providing protection to the developing embryo and endosperm. The integument layers differentiate and harden, creating a barrier that helps prevent desiccation and microbial invasion while allowing for nutrient transfer from the parent plant during seed development. This transformation is crucial for the successful maturation and eventual germination of the seed.
Integuments are modified to form the seed coat but hardening is not essential.
Predators of arthropods include birds, reptiles, amphibians, and other arthropods. Arthropods play important roles in ecosystems as pollinators, decomposers, and prey for other organisms. Their diversity and abundance contribute to the overall health and functioning of ecosystems.
An integument is composed of the skin and its associated components, including hair, nails, and glands. It serves as a protective barrier against physical injury, pathogens, and UV radiation, while also helping to regulate temperature and prevent dehydration. Additionally, the integument contains sensory receptors that allow for the detection of touch, pressure, pain, and temperature.

Arthropods are a fairly wide-ranging classification of animals, covering everything from grub beetles to mosquitoes. One fairly common (though not universal) function of arthropods is to break down organic material into smaller molecules.
Mandibles are jaws and are used for eating.
The integument is a very modern word because it has only been in existence since the seventeenth century. It means the layer that encloses something. For example, a corn husk is an integument.
The major function of the exoskeleton, like for all arthropods, is arguably to protect the soft body inside.

Antennae on some organisms can smell as well as feel.
They express the characteristics inherent to arthropods. All insects are arthropods. Not all arthropods are insects.
