GENERAL HISTOLOGY

Detailed explanation-1: -The adult human skeleton is made up of 206 bones. These include the bones of the skull, spine (vertebrae), ribs, arms and legs. Bones are made of connective tissue reinforced with calcium and specialised bone cells. Most bones also contain bone marrow, where blood cells are made.

Detailed explanation-2: -This is because babies have more cartilage than bone. New born babies have around 305 bones. A baby’s skeleton is mostly made up of cartilage.As a person grows up, most of this cartilage turns into bone in a process called ossification.By adulthood, the skeleton has just 206 bones.

Detailed explanation-3: -The axial skeleton, comprising the spine, chest and head, contains 80 bones. The appendicular skeleton, comprising the arms and legs, including the shoulder and pelvic girdles, contains 126 bones, bringing the total for the entire skeleton to 206 bones.
