Pelvic limb

The pelvic limb is the posterior locomotor apparatus. It articulates with the vertebral column via the pelvis.

It is divided into four major regions:

• the thigh;

• the stifle;

• the leg;

• the hindfoot.

The pelvic limb enables posterior propulsion and supports body weight, particularly in quadrupeds. It is also involved in complex movements such as jumping, running, or standing. In domestic carnivores (dog, cat), the pelvic limb is relatively long and flexible, adapted for rapid running. In ruminants and equids, it is more robust and built for endurance and prolonged weight-bearing.
