| The ischiadic artery was the embryonic important axial artery of the lower limb arising originally from the umbilical artery. |
|
| The popliteal is sometimes a continuation not of the femoral but of a sizable ischiadic artery. |
|
| The main hindlimb artery in Oxyruncus is the ischiadic as in the Tyrannidae, whereas most cotingids possess an enlarged femoral artery. |
|
| In cases where the ischiadic artery persists as the main artery of the lower limb the external iliac is usually poorly developed. |
|
| The distal ends of the pubic bones did not meet on the ventral midline, but the ischiadic portion of the puboischiadic plate was fused at the midline. |
|
| Also, the femoral head, the ischiadic tuberosities, the greater and the lesser trochanter can be approximated by parts of circles. |
