skeleton of a frog

metatarsus

Part of the hind limb formed of five long parallel bones; it connects the tarsus with the first phalanges of the digits.

tarsus

Part of the hind limb formed of several short bones; it is located between the tibiofibula and the metatarsus.

sternum

Long flat bone located in the mid- ventral portion of the body; the clavicle and the coracoid, in particular, are attached to it.

phalanges

Bones articulating to form the skeleton of the digits.

clavicle

Long bone located between the sternum and the scapula.

phalanges

Bones articulating to form the skeleton of the digits.

metacarpus

Part of the forelimb formed of four long bones; it connects the radio-ulna to the first phalanges of the digits.

radio-ulna

Located between the humerus and the metacarpus, the radius and the ulna fuse to form one long bone.

humerus

Long bone of the forelimb articulating with the scapula and the radio-ulna.

tibiofibula

Located between the femur and the tarsus, the tibia and the fibula fuse to form one long bone.

femur

Long bone of the hind limb articulating with the ilium and the tibiofibula.

ischium

Bone situated behind the ilium.

urostyle

Long bone of the posterior portion of the central bony axis; it is formed by several fused vertebrae.

ilium

Large flat bone articulating backward with the sacral vertebra; the juncture of the ilium and the ischium is where the hind limb is attached.

sacral vertebra

Short vertebra located in the posterior portion of the central bony axis and articulating with the ilium.

vertebrae

Short bony parts of the dorsal area of the body forming the central bony axis.

scapula

Large flat back bone.

coracoid

Ventral bone articulating with the sternum; the juncture of the scapula, clavicle and coracoid is the point where the hind limb is attached.

atlas

First cervical vertebra supporting the head and supported by the axis.

frontoparietal

Large flat bone of the upper anterior portion of the cranial box.

mandible

Smooth curved movable bone comprising the lower jaw.

maxilla

Toothed bone comprising the upper jaw.
