What are appedages?

Answer 1

Did you mean Appendages? If so, An appendage is an external body part, or natural prolongation, that protrudes from an organism's body, such as a vertebrate's limbs. In invertebrate Biology, "appendage" is a general term that covers any of the homologous body parts that may extend from a body segment. These include antennae, mouthparts (including mandibles, maxillae and maxillipeds), wings, elytra, gills, walking legs (pereiopods), swimming legs (pleopods), sexual organs (gonopods), and parts of the tail (uropods). Typically, each body segment carries one pair of appendages. Appendages may be uniramous, as in insects and centipedes, where each appendage comprises a single series of segments, or it may be biramous, as in many crustaceans, where each appendage branches into two sections. Triramous (branching into three) appendages are also possible. All arthropod appendages are variations of the same basic structure (homologous), and which structure is produced is controlled by "homeobox" genes. Changes to these genes have allowed scientists to produce animals (chiefly Drosophila melanogaster) with modified appendages, such as legs instead of antennae.

Answer 2

"Appendages" typically refer to external body parts or extensions, such as arms, legs, antennae, or wings, that are adapted for a specific function. In biology, appendages can be found on various organisms, ranging from insects to mammals.
