Arachnids are invertebrates that have eight legs. Spiders,mites,scorpions and ticks are all arachnids. These invertebrates have no wings or antennae.
- Basal Lamina
Extracellular matrix secreted by epithelial cells. Found on the integument of insects.
- Carnoy's Fixative
A tissue fixative comprised of ethanol,acetic acid and chloroform. Used for glycogen preservation and nucleic acids. This fixative is sometimes used for insect tissue.
