This system has 206 bones and associated cartilage, tendons, and ligaments. Because bone is rigid, it gives the body a framework, maintains its shape, and protects vital organs. Bones provide a place for muscles and supporting structures to attach, and, with the movable joints, form a system of levers upon which muscles can act to produce body movements.

A joint is a place of union between two or more bones that may be movable or immovable. Bone also functions as a site for mineral storage and blood cell formation. Tendons and ligaments are strong bands of fibrous connective tissue that attach muscles to bones, and bones to bones, respectively.

Quick Facts

When you were born, you had over 300 bones. When you're an adult, you have about 206. What happened? Did they fall off or something?

The average human adult skeleton
consists of 206 bones, attached to the muscles by tendons. Babies are born with 270 soft bones - about 64 more than an adult. These will fuse together by the age of twenty or twenty-five into the 206 hard, permanent bones

Most of your joints are free-moving joints called synovial joints. These allow you to bend, and jump, and stretch

There are 26 bones in each of your feet, exactly the same number as in your hands.

The parts of an adult skeleton that have fused into one bone include the skull and the pelvis (see the skull). The pelvis came from fusing the ilium bones, the ischium bones and the pubis. The ischium is the bone that you sit down on.

Bones: Our Skeletal System

by: Seymour Simon

Grade 3-5-In his instantly recognizable style, Simon addresses the anatomy and function of bones and muscles. Describing bones as being like "the framework of a building," he emphasizes that they are living parts of the body, protecting organs and manufacturing blood cells and platelets. Explanations of joints, fractures, and arthritis are also included. In Muscles, the three kinds of muscle and their functions are discussed. In addition, the effect of exercise and diagnosing injuries are covered. In both books, the full-paged illustrations are great and include full-color photographs, MRI scans, X rays, and excellent drawings. Two more outstanding additions to Simon's resume.

Your skeleton helps you leap, somersault, and touch your toes -- without it, you would be as floppy as a beanbag! There are over 200 bones living and growing inside you that make up your skeleton. There are also ligaments and joints that hold your bones together, and cartilage in your bendable parts like your ears and your nose. Learn all about what a skeleton can do -- because this isn't some make-believe Halloween skeleton, this is the real skeleton inside you.

appendicular

The skeleton has two main parts - the axial skeleton and the appendicular skeleton.

The axial skeleton is the 80 bones of the upper body. It includes the skull, the vertebrae of the backbone, the ribs and the breastbone. The arm and shoulder bones are suspended from it.

The appendicular skeleton is the other 126 bones -the arm and shoulder bones, and the leg and hip bones. It includes the femur (thigh bone), the body's longest bone.

These books' striking visual impact will draw in even the most casual readers.

The skeleton is the framework of the body. It supports, moves, and protects, allowing us to walk, run, jump, and swim. Eyewitness Skeleton brings its complexity and ingenuity of design vividly to life. Starting with the human skeleton, it explains how each set of bones functions. It examines in detail the construction of the skull, spine and rib cage, hands, arms, legs, and feet. Comparisons are drawn with the bones of birds, reptiles, amphibians, fish, insects, and mammals. See the 206 different bones in the human body, how your skull differs from a lion's or a chimp's, how teeth grow, and what each one is for, and what the inside of a bone looks like. Learn how bones mend themselves when they break, why half the bones in your body are in your hands and feet, how many toes a horse has and what has happened to the tail you once had. Discover which are the smallest bones in the human body, why some creatures wear their skeletons on the outside and what animal once owned the oldest bones ever found on Earth.
