Detailed explanation-1: -Between 17 and 25 years, normal growth stops. The development and union of separate bone parts is complete.
Detailed explanation-2: -The last bones to ossify via intramembranous ossification are the flat bones of the face, which reach their adult size at the end of the adolescent growth spurt.
Detailed explanation-3: -The coccyx, commonly known as the tailbone, is below the sacrum. Individually, the sacrum and coccyx are composed of smaller bones that fuse (grow into a solid bone mass) together by age 30. The sacrum is made up of 5 fused vertebrae (S1-S5) and 3 to 5 small bones fuse creating the coccyx.
Detailed explanation-4: -The clavicle is the first bone to ossify in the devel-oping embryo. At approximately 5 weeks of gesta-tion, primary ossification of the clavicle proceeds by membranous ossification of two centers with no prior cartilaginous anlage.
