At birth the skeleton of a human body has 300 to 350 bones and as a person reaches adulthood, some of these bones get fused together and the adult body is left with 206 bones inside. The bone mass reaches its maximum density by the age of 30.

Most will agree that the full-grown adult has 206 bones, however, this can vary on the individual interpretations also. If you consider the three sternum sections as bones than the adult body has 298 bones in total. The problem in counting them is that it is not easy to distinguish how much they have fused and defused, which is why they are left out. As they are less distinguishable hence they are counted as one bone making the total 206.

The skeleton of a human body comprises of two main parts:

  • The Appendicular Skeleton
  • The Axial Skeleton

The Axial skeleton comprises of the skull, rib cage and the vertebral column while the Appendicular skeleton comprises of the pelvic griddle, the pectoral griddles and the upper and lower limb bones of the body. The bones together form the skeleton and they support these major six functions:

– Support

– Movement

– Protection

– Production of blood cells

– Storing ions

– Endocrine regulation

If the skeleton of the body is broken down, the bones can be categorized like this:

• The skull or the cranial portion has eight bones

• The Facial skeleton has fourteen bones

• The Ossicles (auditory Ossicles) or middle ear has 6 bones

• The Hyoid (lingual) or neck bone is considered 1

• The cervical vertebrate has seven bones (C1 to C7)

• The Thoracic vertebrate has twelve bones (Th1 to Th12)

• The Lumbar vertebrate has five bones (L1 to L5)

• The Sacrum (this is counted as one but varies from 4-6 by age) has one bone

• The Coccyx (counted as one, ranges from 3-5 at young age) is one bone

• The Ribs together are 24

• The Sternum counted is as 1 and has three sections

• The Clavicle is 2 bones

• The Scapula are 2 bones

• The Humerus are 2 bones

• The Radius and Ulna are considered 4 bones in total

• The Carpals are 16 bones in total

• The Metacarpals are 10

• The Phalanges are 28

• There are 2 hip bones and 2 Femurs, total 4

• There are 2 Patella’s

• There are 2 Tibias and 2 Fibulas, total 4 bones

• 14 Tarsal bones are there

• 10 bones make Metatarsal

206 bones in total.

The skeleton is the most interesting part of our body. It is the bones that form the skeleton which gives you the posture of a standing as a human being that can walk, sit, run and do all the movements. To maintain the bone density, which is made of calcium, it is very important for to take adequate calcium throughout the life. A proper knowledge of the bones can help in understanding your body in a better way.
