Oct 25, 2024 · The arthropod’s exoskeleton is therefore somewhat analogous to the armour encasing a medieval knight. Most arthropods move by means of their segmental appendages, and the exoskeleton and the muscles, which attach to the inside of the skeleton, act together as a lever system, as is also true in vertebrates. The external skeleton of arthropods ...
The arthropod body consists of three segments with a hard exoskeleton and jointed appendages. Terrestrial arthropods have adaptations for life on land, such as trachea or book lungs for breathing air. The earliest arthropods were trilobites. The earliest land arthropods were millipedes.
Oct 4, 2019 · An “arthropod” is an invertebrate animal that has an exoskeleton, a segmented body, and jointed appendages. The following families of organisms are all examples of arthropods: Insects such as ants, dragonflies, and bees. Arachnids such as spiders and scorpions. Myriapods (a term which means “many feet”) such as centipedes and milipedes.
Oct 25, 2024 · Arthropod - Exoskeleton, Segmentation, Jointed Appendages: Arthropods have jointed exoskeletons consisting of a thin, outer protein layer called the epicuticle and a thick, inner, chitin–protein layer called the procuticle. The process of growth takes place through molting (ecdysis), which is the shedding of the old exoskeleton.
Oct 25, 2024 · Arthropods lack locomotory cilia, even in the larval stages, probably because of the presence of the exoskeleton. The body is usually segmented, and the segments bear paired jointed appendages, from which the name arthropod (“jointed feet”) is derived. About one million arthropod species have been described, of which most are insects.
Flexi Says: In invertebrate biology, an appendage is an external body part that extend out from an organism's body. Appendages in arthropods can be used for feeding, sensory reception, defense, and locomotion. In addition to legs, antennas and mouth parts are considered modified appendages.

Arthropods (/ ˈɑːrθrəpɒd / ARTH-rə-pod) [22] are invertebrates in the phylum Arthropoda. They possess an exoskeleton with a cuticle made of chitin, often mineralised with calcium carbonate, a body with differentiated (metameric) segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a ...
