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.
The first seven pairs of rib bones (beginning at the top of the sternum) are called true ribs.. They connect to the spine (by ligaments) at the back, and connect to the sternum by costal cartilage in the front. Costal cartilage is elastic and allows the ribcage to expand during respiration.
