details about human bones?

Question

all the details about all the bones in human body

Answer 1

The 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.

The 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 13 and 18, at which point the bones have no pockets of cartilage left to allow more growth.

Not 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.

The 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.

Answer 2

You should contact the NYC police. Only this time, do it by phone and actually speak to someone. Who knows, maybe the letter never got to the station or they may have thought it was a prank. Explain exactly what happened and when in as much detail as you can remember. Since you were so young, the police should understand why you didn't come forward sooner. But whether or not those bones are still there, though, is anyone's guess at this point. A lot of time has passed, but like someone here said, if those bones are still there, you may help to solve a cold case.

Answer 3

There are 206 bones in our skeleton .The bone themselves are divided up into 4 classes:iong bones {which make up the limbs}, short bones {which are grouped together to strengthen our skeleton}, flat bones {which protect our body & provide a place for muscles to attach} , and , our personal favorite irregular bones {those oddly shaped bones that don't fit in of the other three categories}.
While the adult skeleton contains 206 bones but skeleton of an infant contains 350 bones {the bones fuse together as you grow}.And more than half of your 206 bones are found in your hands and feet.
There are 206 bones & 2 systems,the axial skeleton {the trunk of our body} & the appendicular skeleton {our limbs}.
And babies are born with 270 soft bones - about 64 more than an adult;many of these will fuse together by the age of 20 or 25 into 206 hard,permanent bones.




























The average human adult skeleton has 206 bones joined to ligaments and tendons to form a protective and supportive framework for the attached muscles and the soft tissues which underlie it. The skeleton has two main parts: the axial skeleton and the appendicular skeleton.
