true rib การใช้

The true ribs are small projections, with small, hooked bones, called uncinate processes, found on the rear of each rib.
Most of the cartilages belonging to the true ribs, articulate with the sternum at the lines of junction of its primitive component segments.
In humans the second rib is defined as a true rib since it connects with the sternum through the intervention of the costal cartilage anteriorly ( at the front ).
Ribs that articulate directly with the sternum are called " true ribs ", whereas those that connect indirectly via cartilage are termed " false ribs ".
At the lower part of the sternum, where the seventh or last true ribs join it, the ensiform cartilage begins, and above this there is often a depression known as the pit of the stomach.
