COMPARATIVE ANATOMY: PECTORAL GIRDLE OF REPTILE, BIRD AND MAMMAL

The pectoral girdle is connected to the vertebral column through muscles and ligaments. The pectoral girdle consists of two similar halves and each half is formed by three bones namely dorsal, ventral and antero ventral. The dorsal bone is known as scapula, the antero ventral bone is called clavicle and…

COMPARATIVE ANATOMY: PECTORAL GIRDLE OF FISH AND FROG

The skeletal system or skeleton includes the hard parts of the animal body. All the vertebrates possess the endoskeleton (inside the body). These are the living tissues develop from the interior layers of mesoderm of the body. The term skeleton denotes the endoskeleton in vertebrates. Skeleton plays a very important…

COMPARATIVE ANATOMY: RESPIRATORY ORGANS OF FISH (SCOLIODON) AND FROG (RANA)

Scoliodon (fish) is a poikilothermic cartilaginous fish. It is commonly known as shark. Rana (frog) is an amphibian and poikilothermic animal. It is commonly called as frog.   Living cells require energy for performing metabolic activities. This energy is provided by the oxidation of food materials present within the cells.…
