The adult human skeleton is composed of 206 bones. At birth, a baby has 300 bones. As the baby grow and develops, some of these bones fuses or joins together, giving a total of 206 bones afterwards. Together, these 206 bones forms a framework on which the body takes its shape. This frame work is referred to as the skeleton. The human skeleton is upright, giving human an upright appearance. The skeleton also protects the delicate internal organs; for instance, the brain is protected by some bones of the skull. The skeleton also aids movement. You may wish to read some amazing facts in biology here.
Below are a list of all the bones that makes up the human skeleton
Note: Medial is the side closer to the body while lateral is the side away from the body. The manubrium is the upper part of the sternum. The sternum is the bone at the center of your chest. The sternum holds the ribs anteriorly. Both the clavicle and the scapular attaches the upper limbs to the body at the shoulder joint which happens to be the most flexible joint is the human body permitting movement in 360o. This joint is a ball and socket joint.
The thorax extends between the neck and the abdomen. A muscular sheet called the diaphragm separates the thorax from the abdomen. The bones of the thorax protect the heart and the lungs. The thoracic bones are:
Note: The ribs and sternum are important for the breathing process. Some persons may have an extra rib. The term anterior means in front while posterior means behind.
