What are sclerites in insects?

What are sclerites in cockroach?
The entire body of the cockroach, is covered by a hard chitinous exoskeleton. In each segment, exoskeleton has hardened plates called sclerites that are joined to each other by a thin and flexible articular membrane known as the arthrodial membrane.
What is Pronotum in cockroach?
The pronotum is a prominent plate-like structure that covers all or part of the thorax of some insects. The pronotum covers the dorsal surface of the thorax. The American Cockroach (Periplaneta americana) is a common pest species found in the home.
