No. The structures that grow from the body are called 'appendages'. In 'invertebrates' (animals without a backbone or spine, broadly speaking), they include antennae, wings, legs etc. while in 'vertebrates'(animals having a spine, e.g. humans) they include the limbs. Spiracles on the other hand are small openings on the bodies of a few animals that are connected to the respiratory system of the animal and these are used for 'breathing'. Their function is quite similar to that of the nostrils in humans.
in human body they are hard supporting structures called bones
