Answer:

Body regions of arthropod organisms are :

  1. Head
  2. Thorax
  3. Abdomen.

Explanation:

In organisms like spider or scorpion:
there are prosoma (head plus thorax) and opisthosoma (abdomen).

In organisms like centipede and millipede:
there are head and trunk (thorax plus abdomen).

In aquatic crustaceans:
there are cephalothorax (head plus thorax) and abdomen.

In six legged insects, all three parts are distinct. Insects are also the most abundant class of phylum arthropoda.
