How far behind should you stay from another vehicle in traffic?   The universally accepted answer to this is: 2 seconds in normal driving conditions (good weather & dry roads) and 5 seconds in inclement weather (ie: snow and icy â¦roads).
A typical human rib cage consists of 24 ribs, the sternum (with xiphoid process), costal cartilages, and the 12 thoracic vertebrae. Together with the skin and associated fascia and muscles, the rib cage makes up the thoracic wall and provides attachments for the muscles of the neck, thorax, upper abdomen, and back.
There are 24 ribs in the human body, divided into two sets of 12 curved, flat bones. Each one is attached by cartilage at the back to the thoracic vertebrae. The first upper seven ribs are known as 'true ribs' and are directly attached by cartilage to a long flat bone at the centre of the chest called the sternum (breastbone). The remaining pairs of ribs are known as âfalse ribsâ. The eighth, ninth and tenth ribs are also attached to the sternum but not directly.
