1. The Skeleton The skeleton is formed of bones
+ Ligaments + Tendons + Joints
of the body .
The skeleton is formed mainly of bones .

3. The Skeleton Axial Appendicular Skeleton Skeleton = = -Skull Limbs
= =
-Skull Limbs
-Vertebrae &
-Thoracic cage Girdles
-Hyoid bone

6. The Skull The skull is formed of 22 bones.
The mandible is the most mobile one of the skull bones.
The other bones articulate together by fibrous joints .

16. The Thoracic cage The thoracic cage includes the ribs & sternum .
There are 12 pairs of ribs .
The sternum is formed of 3 parts .

24. The Sternum The sternum is formed of : 1- Manubrium sternai
2- Body of the sternum
3- Xiphoid process

29. The Vertebrae ( vertebral Column )
The Cervical vertebrae are 7
The Thoracic vertebrae are 12
The lumbar are vertebrae
The Sacrum are vertebrae
The coccyx is rudimental

31. The Vertebra The vertebra is formed of : -Body = Centrum - 2 Pedicles
- 2 Laminae
- 2 Transverse processes
-Spine
The vertebral canal = spinal canal

35. The Shoulder Girdle The pectoral ( shoulder ) girdle connects
the upper limb with the axial skeleton.
The shoulder girdle includes the clavicle
& the scapula .

40. .The hand Bones of the upper limb The hummers = bone of the arm
The radius = the lateral bone of forearm
The ulna = the medial bone of forearm
The Carpals = 8 bones ( bones of the
wrist )
.The hand

42. HUMERUS

50. The Pelvic Girdle The pelvic girdle is formed of 2 hip bones + Sacrum.
The 2 hip bones are connected together anteriorly by the symphysis pubis which is a cartilaginous joint .

57. Bones of the lower limb The femur = bone of the thigh
The tibia = the medial bone of leg
The fibula = the lateral bone of leg
The tarsal bones are 7
