The Skeleton• The skeleton is formed of bones
+ Ligaments + Tendons + Joints
of the body .
• The skeleton is formed mainly of bones .
The Skeleton
• Axial Appendicular
• Skeleton Skeleton• = = • -Skull Limbs• -Vertebrae &• -Thoracic cage Girdles• -Hyoid bone
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 .
The Thoracic cage
• The thoracic cage includes the ribs & sternum .
• There are 12 pairs of ribs .
• The sternum is formed of 3 parts .
The Sternum
• The sternum is formed of :
• 1- Manubrium sternai
• 2- Body of the sternum
• 3- Xiphoid process
The Vertebrae( vertebral Column )
• The Cervical vertebrae are 7
• The Thoracic vertebrae are 12
• The lumbar are vertebrae 5
• The Sacrum are vertebrae 5
• The coccyx is rudimental
The Vertebra• The vertebra is formed of :• -Body = Centrum• - 2 Pedicles• - 2 Laminae• - 2 Transverse processes• -Spine• The vertebral canal = spinal canal
The Shoulder Girdle
• The pectoral ( shoulder ) girdle connects
the upper limb with the axial skeleton.
• The shoulder girdle includes the clavicle
& the scapula .
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
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 .
Bones of the lower limbBones 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
• The other bones of the foot
