Morphological divisions—endoskeleton vs. exoskeleton From the perspective of comparative morphology, including paleontology, it has been suggested that two lineages of skeletal systems—the endoskeleton and exoskeleton—have succeeded in vertebrate evolution (Figure 1, Table 1) [7,11]. The organic component is primarily collagen, which gives bone great tensile strength.

It must be recognized, however, that this muscle, although probably the most extensively studied vertebrate skeletal muscle, is actually rather a specialized example. Kidneys are organs that filter wastes from blood so they can be excreted from the body. x�}ν Replies. Humans are vertebrates, animals having a vertabral column or backbone.They rely on a sturdy internal frame that is centered on a prominent spine.The human skeletal system consists of bones, cartilage, ligaments and tendons and accounts for about 20 percent of the body weight.. Its function is to receive the stimulus from the receptors and transmit its response to the effectors.

Composition of Fish Skeletal System. There are two different skeletal types: Exoskeleton- An outer shell of an organism. This mode of classification is defined exclusively by phylogenetic continuities, and thus differs from terminology based on ontogeny [7].
