The ischium is caudal and forms most of the pelvic floor. The '''ischial tuberosity''' is formed by the caudolateral corner of the  horizontal plate of the ischium. The '''Pelvic Symphysis''' comprises both the pubis and the ischium .

==Species differences==

Larger species have a more vertical ilium, bringing the sacroiliac joint (and with it the weight of the trunk) closer to the hip. Smaller species have an oblique ilium. The dog has a stout cord extending between the sacrum and lateral ischial tuberosity, this is not present in the cat. In ungulates, the '''sacrosciatic ligament''' expands to a broad sheep.
