Fig. 2. A right lateral view of a cheetah showing joint locations and conventions for measuring angles of the joints (A) and the long bones relative to vertical (B). The image is near midstance of the right forelimb and late stance of the right hindlimb. From proximal to distal, joint angles were labeled as follows: elbow, wrist, metacarpal–phalange (MCP) for the forelimb and knee, ankle, and metatarsal–phalange (MTP) for the hindlimb. From proximal to distal, the names of the angles relative to vertical (B) are humerus, radius and metacarpals for the forelimb, and femur, tibia and metatarsals for the hindlimb. The angles relative to vertical (B) were positive when the distal portion of a limb segment was anterior to its proximal portion and negative when the distal portion of a limb segment was posterior to its proximal portion.
