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 attaches to the ribs via the costal cartilage. It is an essential component of the thoracic area and carries out the important function of protecting the glands and organs present in the thoracic cavity.  The sternal angle is situated at the meeting point of the gladiolus and the manubrium.
