There are 206 bones in the human body.
The skeleton has two major divisions
AXIAL and APPENDICULAR

The axial
skeleton
forms the
long axis of
the body and
includes the
bones of the
skull,
vertebral
column, and
rib cage.
The skull consists of two sets of bones – the
cranium and the facial bones. There are
eight cranial bones and fourteen facial
bones.
 The joints between bones of the skull are
immovable and called sutures.

The vertebral column consists
of vertebrae separated by disks
of fibro-cartilage.

7 cervical vertebrae
 12 thoracic vertebrae
 5 lumbar vertebrae
The bony thorax forms a cage
to protect major organs
SPINAL
(VERTEBRAL)
COLUMN
The spinal column
(or vertebral column)
extends from the
skull to the pelvis
and is made up of 33
individual bones
termed vertebrae.
The bony thorax is made up of three parts:
1)Sternum
2)Ribs
3)Thoracic vertebrae
You have three different types of ribs
 True ribs are the first seven pairs of ribs. True
ribs attach directly to the sternum by costal
cartilages.
 False ribs are the next five pairs. They either
attach indirectly to the sternum or not at all.
 Floating ribs are the last two pairs of false ribs.
They lack sternal attachments.
