Describe Arthropods body
(Similar to annelida/worms)
- Body is segmented.
- Each segment have appendages.
- NOT SEPARATED INTERNALLY BY SEPTA.
- MOST ORGANS ARE NOT METAMERICALLY ARRANGED.
- Note: Metamerism allows for regions within the arthropod body to carry out speciallized functions.
- Regional Specialization is called Tagmatization.
What is regional specialization called?
Tagmatization
What permits specialization of regions of the arthropods body to carry out specific functions?
(Starts with M, Meta)
Metamerism

What is Tagmentization
Where regions in the body of arthropoda are specialized to carry out a specific function.
