The appendicular skeleton supports the attachment and functions of the upper and lower limbs of the human body. It is obvious that our knowledge about the evolution and development of cartilage and bone formation, as well as the evolutionary sequence of postcranial parts, increased. Appendages first appeared during the early evolution of the fishes.usually two pairs of appendages are present, fins in fish and limbs in land vertebrates.

The Posterior Girdle Is The Hip Or Pelvic Girdle, Consisting Of.

Here, we provide a broad overview of the evolutionary development of the postcranial skeleton of all extinct and extant fish lineages in a phylogenetic and genetic framework. The pectoral girdle is positioned just posterior to the neurocranium. Examine the microscope demonstration of dry ground bone.

While Most Fish Species Use The Undulating Contractions Of The Axial Musculature To Generate Propulsive Force, Tetrapods Also Rely On The Appendicular Muscles Of The Limbs To Generate Movement.

The exoskeleton, which is the stable outer shell of an organism, and the endoskeleton, which forms the support structure inside the body.the skeleton of the fish is made of either cartilage (cartilaginous fishes) or bone (bony fishes). Paired appendages are not found in ancestral vertebrates and are not present in the modern cyclostomes (e.g., lampreys, hagfishes). The appendicular skeleton consists of skeletal elements of pectoral and pelvic girdles, and of the appendages.

The Axial Skeleton Skull The Skull Of The Perch Is Actually A Double Structure Consisting Of Two “Boxes” Of Bone, One Enclosed By The Other.

Made Up Of The Pectoral Girdle And Appendages Fins/Limbs That Extend Off Of Axial Skeleton, Connected To Axial Via Girdle.

Starting from the head, bony fish consist of solid hard bones called cranium. The evolution of terrestrial tetrapod species heralded a transition in locomotor strategies. Appendages first appeared during the early evolution of the fishes.usually two pairs of appendages are present, fins in fish and limbs in land vertebrates.
