Frog Skeleton

• • Maxilla – Forms the upper jawbone
• • Atlast – The top part of a backbone
• • Suprascapula – Shoulder blade
• • Vertebrae – Individual bones that form the spine
• • Sacral Vertebra – A bone below the last vertebra, positioned between the hips
• • Urostyle – A long, thin bone at the base of the lower vertebrates
• • Ilium – A flat bone stretching backward from the Sacral Vertebra
• • Femur – Upper bone of the rear limb
• • Tibiofibula – A single bone commonly known as the shinbone
• • Tarsus – Several bones formed between the Tibiofibula and Metatarsus
• • Metatarsus – Bones forming the foot of a limb
• • Phalanges – Several bones forming fingers or toes of a limb
• • Humerus – Upper bone of the front limb
• • Radio-ulna – A forelimb bone
• Cranium – The front of a frog’s cranium is more developed than the back. It serves to protect the brain.
• Sense Capsules – Cartilaginous cavities which contain the sensory organs: eyes, nose, etc.
• Jaws – The upper and lower jaws support the border of the mouth.
• • Episternum is the upper part of the sternum.
• • Omosternum is in between the episternum and clavicle on a frog.
• • Clavicle is essentially a frog’s collarbone. It is in between the shoulder and sternum.
• • Humerus is the first bone in the front leg of a frog. It runs between the shoulder and elbow.
• • Procoracoid is the amphibian equivalent of a coracoid 
• • Sternum is connected between each half of the pectoral girdle, between the Xiphisternum and Propcoracoid.
• • Xiphisternum is the lowest piece of the sternum.
• • Ilium – A bone forming the upper part of the pelvis
• • Urostyle – Formed from fused vertebrae at the base of the backbone
• • Acetabulum – A socket of a frog’s hip, in which the femur bone fits
• • Ischium – A curved bone at the base of the pelvis
