Vetinerary Assistant Practice Exam

Which of the following is a part of the thoracic limb?

1. Pelvis

2. Carpal bones

3. Tarsal bones

4. Achilles tendon

The correct answer is: Carpal bones

The thoracic limb, also known as the front limb, consists of several anatomical structures that facilitate movement and support for the animal. The carpal bones, which are part of the forelimb, form the carpus or wrist area in animals. This structure is critical for the range of motion and articulation with the forearm bones, particularly in quadrupeds. The other options refer to components of different anatomical regions. The pelvis is associated with the pelvic limb, while the tarsal bones are part of the hind limb structure, forming the ankle in animals. The Achilles tendon, known for its role in connecting the calf muscles to the heel bone, is likewise related to the hind limb. Therefore, the carpal bones uniquely fit the criteria of belonging to the thoracic limb, making it the correct answer.
