The Smell Report. Smell is not just a biological and psychological experience, it is also a social and cultural phenomenon. Smell is probably the most undervalued of the senses in modern Western cultures. Yet cultural historians have shown that this was not always so: the current low status of smell in the West is a result of the ârevaluation of the sensesâ by philosophers and scientists of the 18th and 19th centuries.
Ribs: There are 12 pairs of ribs, all of which are attached posteriorly to the respective thoracic vertebrae. The upper 7 pairs are attached to the sternum directly through their costal cartilages. Ribs 8 through 10 are attached indirectly to the sternum through the seventh costal cartilage. Their costal cartilages are also attached with each other at different points.
1 The sternum connects to the ribs via cartilage. 2  The primary function of the sternum is the protection of the heart, lungs, and blood vessels from physical damage. 3  Most of the sternum is made up of vascular tissue, only a thin layer of bone covers the outside of this tissue.
