The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birthand decreasesto 206 when adult.. It can be divided into axial skeleton and appendicular skeleton.

The axial skeleton is formed by  vertibral column ( 30 -34 bones) , rib cage ( 12 pair of ribs) and skull ( 22 bones and 7 associate bones) and other bones. It contain 80 bones .

The appendicular skeleton is formed by shoulder gridle, pelvic gridle and bones of upper and lower limbs. It consists of 126 bones

The human skeleton is made up of 206 bones, including bones of the:

• Skull – including the jaw bone
• Spine – cervical, thoracic and lumbar vertebrae, sacrum and tailbone (coccyx)
• Chest – ribs and breastbone (sternum)
• Arms – shoulder blade (scapula), collar bone (clavicle), humerus, radius and ulna
• Hands – wrist bones (carpals), metacarpals and phalanges
• Pelvis – hip bones
• Legs – thigh bone (femur), kneecap (patella), shin bone (tibia) and fibula
• Feet – tarsals, metatarsals and phalanges.
• There are four different types of bone in the human body:
• Long bone – has a long, thin shape. Examples include the bones of the arms and legs (excluding the wrists, ankles and kneecaps). With the help of muscles, long bones work as levers to permit movement.
• Short bone – has a squat, cubed shape. Examples include the bones that make up the wrists and the ankles.
• Flat bone – has a flattened, broad surface. Examples include ribs, shoulder blades, breast bone and skull bones.
• Irregular bone – has a shape that does not conform to the above three types. Examples include the bones of the spine (vertebrae)  .... Thanks..
