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.
Humans have 24 ribs (12 pairs). The first seven sets of ribs, known as  true ribs  (costae verae), are directly attached to the sternum through the costal cartilage. Rib 1 is unique and harder to distinguish than other ribs.umans have 24 ribs (12 pairs).
