The human skeleton is the building block and the framework of the body. At birth, we have approximately 270 bones. Due to some bones being fused at birth, some people will have varying amounts of bones. By adulthood, the total number of bones drops to 206 as more bones are fused as part of the maturation process.
Human bones are categorized into two groups: the axial skeleton, which contains the bones along the long axis or core of the body (i.e., the head and the torso,) and the appendicular skeleton, which includes the bones of the appendages. Since your body has two symmetrical sides, we have 172 of the 206 human bones as part of a pair including all 126 bones of the appendicular skeleton and 46 of the 80 bones in the axial skeleton. The 34 unpaired bones are bones along the center of the body which includes six skull bones, 26 vertebrae, the sternum of the chest, and the hyoid bone under the chin.
Bones make up the skeletal system, which also includes ligaments, cartilage, tendons, and joints. The skeletal system gives your body its shape and works as a bony armor to protect your vital organs, including your brain, spinal cord, lungs, and heart. Bone is also a storage area for minerals alone broth vitamins, bone marrow, and fat. Your skeletal system also allows for movement by providing attachment
