Quizplus · Accepted Answer

The appendicular skeleton includes the bones of the limbs or fins, which are connected to the body's main axis by the pectoral and pelvic girdles. The axial skeleton, on the other hand, includes the bones of the skull, vertebral column, and ribcage, which form the central axis of the body. The endoskeleton refers to the internal skeleton of vertebrates, while the hydrostatic skeleton is a type of skeletal system found in invertebrates like worms and jellyfish. Exoskeletons are hard, external structures found in many invertebrates, such as insects and crustaceans.
