1. ARTICULATIONS OF THE VERTEBRAL COLUMN AND RIBS THERE ARE NINE TYPES OF JOINTS IN VERTEBERAES

2. Waqas Nawaz 11-ARID-975 ANAT 102

3. 1. ATLANTO-OCCIDITAL JOINT (YES JOINT) Occipital condyle and cranial articular fovea It is same in ox dog and horse FUNCTION Hing joint dorsal and ventral flexor (lateral movement)

4. ARTICULATIONS OF THE VERTEBRAL COLUMN AND RIBS

5. 2 ATLANTO – AXIAL JOINT In ox Fovea of the dens and caudal articular fossa of the atlas, dens and ventral articulation surface of the dens FUNCTION Axial rotation of the head on the neck, head shaking

6. 2 ATLANTO – AXIAL JOINT

7. 2 ATLANTO – AXIAL JOINT IN HORSE AND DOG Atlas saddle-shape facets and reciprocal saddle shaped surfaces extend upon the dens confident on ventral aspect FUNCTION Atlas and the head rotate upon the axis, axis of rotation passes through centre of body of axis

8. 2 ATLANTO – AXIAL JOINT

9. 3. JOINTS OF THE ARTICULAR PROCESS Articular process of adjacent vertebrae FUNCTION Sliding joints Is same in dog horse and ox

10. 3. JOINTS OF THE ARTICULAR PROCESS

11. 4. COSTO – VERTEBRAL JOINTS Articular surface of the head of the rib and caudal costal fovea of the more cranial vertebrae and cranial costal fovea of the more caudal vertebrae with which the ribs head articulate FUNCTION Hinge joint that together with the vertebrae makes possible the variation of thoracic volume in respiration

12. 4. COSTO – VERTEBRAL JOINTS IN DOG Articular surface of the head of the rib and caudal costal fovea of the more cranial vertebrae and cranial costal fovea of the more caudal vertebrae with which the ribs head articulate FUNCTION Hinge joint that together with the vertebrae makes possible the variation of thoracic volume in respiration

13. 4. COSTO – VERTEBRAL JOINTS

14. 4. COSTO – VERTEBRAL JOINTS IN OX AND DOG Each ribs form two joint by head ( costo -central) and by tubercle ( costo -transverse joint) FUNCTION The movement is very limited in the anterior part of series of joints but considerable in the posterior part

15. 4. COSTO – VERTEBRAL JOINTS In horse and ox

16. 5. COSTOTRANSVERSE JOINT JOINTS OF RIB TUBERCLE In dog Articular surfaces of the costal tubercle and the costal fovea of the transverse process of the same numbered (more caudal vertebrae FUNCTION Hinge joint

17. 5. COSTOTRANSVERSE JOINT JOINTS OF RIB TUBERCLE DOG

18. 5. COSTOTRANSVERSE JOINT JOINTS OF RIB TUBERCLE IN HORSE From by facet of the tubercle of the rib and on transverse process of the vertebrae FUNCTION Gliding joint Movement is very limited

19. 5. COSTOTRANSVERSE JOINT JOINTS OF RIB TUBERCLE HORSE

20. 5. COSTOTRANSVERSE JOINT JOINTS OF RIB TUBERCLE IN OX There are no intertransverse joints form by facet of tubercle of rib and transverse process of the vertebrae FUNCTION Gliding joint Movement is very limited

21. 5. COSTOTRANSVERSE JOINT JOINTS OF RIB TUBERCLE OX

22. 6. STERNO – COSTAL JOINT Cartilaginous ends of the first to the eight rib and sternum IN OX DOG AND HORSE IT IS SAME FUNCTION Hinge joint

23. 6. STERNO – COSTAL JOINT

24. 7. COSTO-CHONDRAL SYNCHONOROSES In dog Costal bone and costal cartilage FUNCTION Nearly rigid and immoveable

25. 7. COSTO-CHONDRAL SYNCHONOROSES DOG

26. 7. COSTO-CHONDRAL SYNCHONOROSES IN HORSE Rib has concave surface which receive convex end of the cartilage FUNCTION Nearly rigid and immoveable

27. 7. COSTO-CHONDRAL SYNCHONOROSES HORSE

28. 7. COSTO-CHONDRAL SYNCHONOROSES IN OX Cartilages are attached to each other by distinct elastic ligament FUNCTION Limited lateral movement is possible

29. 7. COSTO-CHONDRAL SYNCHONOROSES OX

30. 8. STERNAL SYNCHONDROSIS IN DOG Monubrium of the sternum of the body of the sternum xiphoid process FUNCTION Increasingly rigid and immoveable

31. 8. STERNAL SYNCHONDROSIS IN DOG

32. 8. STERNAL SYNCHONDROSIS IN HORE Seven bond segments are united by persisting cartilage in new-born foal FUNCTION Increasingly rigid and immoveable

33. 8. STERNAL SYNCHONDROSIS HORSE

34. 8. STERNAL SYNCHONDROSIS IN OX First segment of sternum FUNCTION Increasingly rigid and immoveable

35. 8. STERNAL SYNCHONDROSIS

36. 9. INTERVETEBRAL SYMPHYSIS (JOINTS BETWEEN ADJACENT VERTEBRAE) Bodies of adjacent vertebrae starting with the axis and including it caudal vertebrae In HORSE and DOG it is same FUNCTION Slight mobility

37. 9. INTERVETEBRAL SYMPHYSIS (JOINTS BETWEEN ADJACENT VERTEBRAE)

38. 9. INTERVETEBRAL SYMPHYSIS (JOINTS BETWEEN ADJACENT VERTEBRAE) IN OX Intervertebral ligaments are thicker than Horse FUNCTION Slight mobility

39. 9. INTERVETEBRAL SYMPHYSIS (JOINTS BETWEEN ADJACENT VERTEBRAE)
