Study Notes
Insect Integument
- The insect integument provides protection, support, and maintains internal environment.
- It is composed of three main layers: epicuticle, exocuticle, and endocuticle.
Cuticle Layers
- The epicuticle is the outermost layer, lacking chitin.
- It consists of a thin, impermeable layer of lipids and waxes.
Chitin-containing Layer
- The procuticle (also known as exocuticle and endocuticle) is the layer that contains chitin.
- Chitin is a polysaccharide that provides strength and flexibility to the cuticle.
Basement Membrane
- The basement membrane is a thin, acellular layer that separates the epidermis from the hemocoel.
- Its main function is to provide a substrate for muscle attachment and maintain the position of the epidermis.
