Why the bones of a child is differ to a man?

The bones don't dissappear, they just fuse together.  Adults have a solid skull, but babies have the skull made of several different sections, which makes it slightly flexible, and capable of growth.\n\nThe joints also have a number of "bones" which join other bones.  These are called the Ephyses (sp?) all animals have them, so if you're cooking up like the hank, or the shank of a cow or pig or something, you can see them.  Near the joint, the bone has all these lumps, and if you cook it forever, they'll usually fall off into the separate bones.  \n\nWhen a creature reaches full size, these ephyses fuse to the rest of the bone.  Actually, each one has a different range of time when they fuse, and archaeologists can study which ones have fused to determine the age a skeleton was when the person died.\n\nSo now you know.

The human body contains 206 bones!\n\nThe human skeleton is made of individual or joined bones (such as the skull), supported and supplemented by a structure of ligaments, tendons, muscles, cartilage and other organs.\n\nThe skeleton is not unchanging; it changes composition over a lifespan. Early in gestation, a fetus has no hard skeleton; bones form gradually during nine months in the womb. At birth, all bones will have formed, but a newborn baby has more bones than an adult. On average, an adult human has 206 bones (according to Gray's Anatomy, but the number can vary slightly from individual to individual), but a baby is born with approximately 300 bones. The difference comes from a number of small bones that fuse together during growth, such as the sacrum and coccyx of the vertebral column. An infant is born with pockets of cartilage between particular bones to allow further growth. The sacrum (the bone at the base of the spine) consists of five bones which are separated at birth but fuse together into a solid structure in later years. Growing is usually completed between ages 12 and 14, at which point the bones have no pockets of cartilage left to allow more growth.\n\nNot all bones are interconnected directly. There are 6 bones, the auditory ossicles (three on each side), in the middle ear that articulate only with each other. Another bone, the hyoid bone in the neck, does not touch any other bones in the body, and is supported by muscles and ligaments; it serves as the point of attachment for the tongue.Also some of the ribs called the floating ribs only hang by Muscle and are not attached to the spine.\n\nThe longest and heaviest bone in the body is the femur and the smallest is the stapes bone in the middle ear. In an adult, the skeleton comprises around 20% of the total body weight.

There is, apparently some evidence that intensive training in gymnastics can slow skeletal development.  I imagine this is more evident at the elite gymnast level.  I think gymnasts tend to be smaller, on average, because the lower centre of gravity is beneficial for some of the apparatus.  Health problems in gymnasts are more pronounced for girls than boys.  You are probably a good size for a gymnast.

Here's an answer that wasn't copied and pasted from somewhere on the net...\n\nLong bones, which are the bones of your arms and legs, can be broken into two regions. The "knobs" located at both ends of the bone are called the epiphyses. The long, narrow portion of the bone is called the diaphysis. Located at each end of the bone between the epiphysis and diaphysis is a region called the epiphyseal plate.\n\nThe epiphyseal plate is more commonly referred to as the "growth plate". In a growing human, the epiphyseal plate contains many chondrocytes. The chondrocytes produce chondrin, which is the material that composes cartlidge. This new cartilidge lengthens the bone. Osteoblasts then convert this newly formed cartlidge into bone.\n\nIn adult humans who have finished growing, the epiphyseal plate has been completely replaced by solid bone. A quick x-ray can therefore determine whether an adult human has finished growing by the presence or absence of the epiphyseal plate.\n\nChondrocytes are also located in other parts of the body where cartlidge is present, like the nose, ears, larynx, trachea, and skeletal joints.

b. Babies have more bones but when they grow up these bones merge, combining to a total no. of 206 bones.

Of the hundreds of causes of dwarfism in humans, most are genetic, and most involve single gene variations that affect the structure or metabolism of bone, cartilage, or connective tissue. This class of disorder is referred to by physicians as skeletal dysplasia. Chondrodystrophy, chondrodysplasia, osteochondrodystrophy are also used (fairly interchangeably) in the medical literature to refer to most of these conditions. In many of these conditions, the bones are the primary affected body part, and the person is otherwise healthy. In many others, the genetic difference affects other body systems, causing unusual features or other major problems. Achondroplasia is one of the most common and perhaps the most easily recognized skeletal dysplasia. It affects approximately 1 in 40,000 children, both males and females, as it is due to a mutation of an autosomal gene.

Simply, their hips are wider, for the species to continue as is, their hips are wide to push those big ol' baby brains through their pelvis.  Anthropologists can use the lower limbs only to determine likely gender in this way.

it's probably not osteoporosis, it's probably Scoliosis. Which is very common, go see your pediatrician

On average, an adult human has 206 bones (according to Gray's Anatomy, but the number can vary slightly from individual to individual), but a baby is born with approximately 300 bones. The difference comes from a number of small bones that fuse together during growth, such as the sacrum and coccyx of the vertebral column.\n\nThe number of bones per area:\nSkull (22) \nChest (25)\nVertebral column (26)  \nFeet (52) \nHands (54)\n\nSo the hands have the most bones.

Because when they are a fetus in the womb both males and females grow in the same way upto a certain time when sexual charcteristics develop. \nMales stop growing in that area cause they do not need them for survival whereas females need them for breastfeeding so development continues.  \n\nI think apes have them to!

Well, i'm not an expert, but as i understand it, the basic difference, besides the composition, is that cartilage is flexible. the human body uses cartilage to connect the bones to each other so that we have joints and can move in many different ways. It actually has many other functions too. here is a good link to learn more about cartilage:\nhttp://www.botany.uwc.ac.za/sci_ed/grade10/mammal/cart.htm\n\ncomparison of characteristics of both (kinda techinical)\nhttp://bms.brown.edu/curriculum/b189/Lectures/cart-bone-study.htm

The difference between a man and a boy is the man takes responsibility for his actions.  Boys will lie.

Males tend to be stronger and faster.\n\nI hate people that disagree with this statement and feel it's a put down to women.  It's not, it's genetics, it happens, why is it so hard to grasp?

average human body has 206 bones.  Some have one or two more or less.\n\nas for the joints, I've only had one today...

Because men can survive in this world much easier than women. A man's body is better equiped for defence/violence. It's even easier for men to find a quality job as necessary. Lastly, women are often left with children. Making life that much more difficult.

It depends on how old you are. When babies are born the skull is broken up into many pieces. As you grow older they gradually fuse together into larger pieces.
