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.
