1. Blood cell production; usually occurs in red bone marrow.

2. Another name for cancellous bone.

3. Process on the cranial end of the second cervical vertebra (axis) that fits into the caudal end of the first cervical vertebra (atlas).

4. The large metacarpal and metatarsal bones (III) of the horse.

5. An immovable fibrous joint - such as the suture that unites most of the skull bones.

6. One of two small sesamoid bones located in the proximal gastrocnemius muscle tendon just above and behind the femoral condyles of dogs and cats.

7. The growth plate of a long bone; located at the junction of the proximal and distal epiphyses with the diaphysis. They are areas where long bones increase in length by the process of endochondral bone formation. When an animal reaches its full adult

8. Also called a spheroidal joint - it consists of a spherical joint surface (the ball) that fits into a closely matching - concave joint surface (the socket). Examples: shoulder and hip joints. Capable of all synovial joint movements.

9. Another name for a pivot joint; one bone pivots on another in a rotary motion. The only true pivot joint is the atlantoaxial joint.

10. The main - weight - bearing bone of the lower leg; forms the stifle joint with the femur proximal to it and the hock with the tarsus distal to it.

11. A gliding joint in which two flat - articular surfaces rock on each other; this type of joint usually allows only the movements of flexion and extension.

12. The kneecap; the largest sesamoid bone in the body; located on the front surface of the stifle joint in the tendon of the large quadriceps femoris muscle. It rides in the trochlea of the femur.

13. Incoordination; animals with this make jerky - spastic movements.

14. Skull bones that are part of the external bones of the face; these two bones are the most rostral skull bones and contain the upper incisors in all domestic animals except ruminants.

15. Skull bones that are part of the internal bones of the face; make up the caudal portion of the hard palate.

16. One of two concave - half moon - shaped - cartilaginous structures on the proximal surface of the tibia that help support the condyles of the femur.

17. The fibrous membrane that covers the outsides of bones except for their articular surfaces.

18. One of the two bones (with the ulna) that form the antebrachium - or forearm; usually the main weightbearing bone.

19. The area of a bone that joins the head with the main portion of the bone.

20. The outer layer of a bone that is composed of compact bone.

21. A slightly movable cartilaginous joint - such as the pubic symphysis.

22. The joint between the femur and the tibia; called the knee joint in humans.

23. The most caudal rib or two in the rib cage; a rib whose costal cartilage does not unite with anything but rather ends in the muscle of the thoracic wall.

24. A joint movement that consists of a twisting motion of a part on its own axis.
