Rib, sternal
The lower five ribs do not directly connect to the sternum and are known as false ribs.
The upper three false ribs connect to the costal cartilages of the ribs just above them. The last two false ribs, however, usually have no ventral attachment (no anchor at all in front) and are called floating, fluctuating or vertebral ribs.

- Ribonucleic acid (RNA)
Messenger RNA (mRNA) is a type of RNA that reflects the exact nucleoside sequence of the genetically active DNA. mRNA carries the “message” of the DNA to the cytoplasm of cells where protein is made in amino acid sequences specified by the mRNA. Transfer RNA (tRNA) is a short-chain type of RNA present in cells. […]
- Ribonucleoprotein (RNP)
A combination of ribonucleic acid (RNA) and protein. In autoimmune diseases, antibodies can form against ribonucleoprotein. They are called anti-RNP antibodies.
- Ribosomal RNA
A molecular component of a ribosome, the cell’s essential protein factory. Ribosomal RNA (rRNA) fabricates polypeptides (assemblies of amino acids that make up proteins). A tiny particulate structure located in the cytoplasm of the cell (outside the nucleus), the ribosome is composed of two subunits, one larger than the other. Both subunits were believed to […]
