Rotating the lower bone, changing the angle of interaction
-
Replacing the ligament with one from a dead dog
-
Removing the leg
-
Replacing the ligament with a plastic strip
A
Correct answer
Explanation
The most common surgical repair for a torn ACL in dogs is the TPLO (Tibial Plateau Leveling Osteotomy). This procedure involves cutting the tibia and rotating the bone to change the angle of the joint, which stabilizes the knee without needing the ligament itself.

An artery
-
A bone
-
A nerve
-
A ligament
C
Correct answer
Explanation
The 'funny bone' is not a bone at all, but the ulnar nerve, which runs along the humerus bone and is sensitive to impact.
D
Correct answer

The five main ligaments of the knee are the ACL, PCL, MCL, LCL, and the recently identified ALL.
-
exoskeletons are on the outside; skeletons are on the inside
-
exoskeletons are harder than a human skeleton
-
exoskeletons are on the inside; skeletons are on the outside
-
exoskeletons provide support; human skeletons do not
A
