Study Notes
Arthropod Biology
- The exoskeleton of arthropods is primarily made up of chitin, a polysaccharide.
- Arthropods grow through a process of molting, where they shed their exoskeleton and undergo a series of instars before reaching adulthood.
- The analogue of blood for most arthropods is hemolymph, a clear fluid that circulates nutrients and oxygen throughout the body.
- Arthropods have an open circulatory system, where the hemolymph bathes organs directly and is not confined to blood vessels.
- The nervous system in arthropods is described as a ventral nerve cord, consisting of a double cord of nerve cells that extends along the length of the body.
