Skeletal System
The skeletal system includes all of the bones and joints in the body. The skeletal system in an adult body is made up of 206 individual bones. These bones are arranged into two major divisions: the axial skeleton and the appendicular skeleton. The axial skeleton runs along the body’s midline axis and is made up of 80 bones in the following regions:
These are 20 of the major bones in the Human Body Skeleton:
Cranium
Mandible
Clavicle
Sternum
Humerus
Vertebra
Radius
Carpals
Metacarpals
Phalanges
Femur
Patella
Fibula
Tibia
Ulna
Tarsals
Metatarsals
Pelvis
Bone composition:
Bone itself consists mainly of collagen fibres and an inorganic bone mineral in the form of small crystals. In vivo bone (living bone in the body) contains between 10% and 20% water. Of its dry mass, approximately 60-70% is bone mineral.
Injuries or Disorders related to this system:
Bursitis, Spina Bifida, Osteoporosis, Osteoarthritis,Rheumatoid Arthritis,Scoliosis, Rickets,
Kyphosis, Talipes equinovarus, tendinitis, poliomyelitis, etc.
