    BONES FOUND AT THE DORSAL SIDE OF THE FROG: Premaxilla-are small bones at the anterior most part. It is surrounded by maxilla. Maxilla-are elongated V-shaped tooth with bone having a long process that extends to the nasal capsule. Nasal Bones-are triangular in shape. It is located posterior to the premaxilla. Sphenethmoid-also called as mesethmoid is the frontal part of the braincase. Dorsally, it looks like a small circular area at the junction between the nasal and the fronto-parietal bones. Fronto-parietal bones-are paired elongated flat bones posterior to the nasal and are surrounded at its back by otic capsule. Prootic bones-are found at the lateral to the posterior part of the fronto-parietal bones. Squamosal bones-are the hammer-shaped bones that form the wall of the orbit. Foramen magnum-is the opening at the ossified posterior end of the occipital region for the passage of the spinal cord. Occipital bone-is the bone that occupies the rear end of the skull. It lines the foramen magnum. BONES LOACTED AT THE VENTRAL SIDE OF THE FROG’S SKULL: Vomer bone-is located at the center of the skull. It bears the vomerine teeth. Prootic bone-is a pair of bones at the anteroventral wall of the otic capsule. Parasphenoid bone-is the bone located ventral to the fronto-parietal bone. It is shaped like a dagger. It forms the floor of the cranium and the ventral wall of the otic capsule. Palatine bone-is a pair of the triangular bones. It originates from the maxillary arch. Pterygoid bone-is a three-layered bone. It is attached to the maxilla, prootic, and squamosal. BONES AT THE LOWER JAW: Mento-meckelian part-bone that can be seen only at the anterior part of the jaw. Dentary portion-a dental bone characterized by the absence of teeth. Angulo-splenial-another dermal bone whose rear end is in contact with the posterior arm of the pterygoid. HYOID APPARATUS-is the cartilaginous part of the skull which is divided into five parts: Central flat cartilage-is the body of the hyoid apparatus. Horns-are paired horns located at the anterior portion (also called as cornua). Paired posterior horns Alary processes-are the only bony parts of the hyoid apparatus. Thyroid processes-are the attachment of the larynx. Pectoral girdle-is the U-shaped framework of the thorax. Pectoral-refers to the upper thoracic region of the body.
