The term "costal cartilage" refers to the pieces of hyaline cartilage that connect the ribs to the sternum. The spelling of this word can be explained using the International Phonetic Alphabet (IPA) phonetic transcription system. The initial sound, "k", is represented by the IPA symbol /k/. The following vowel sound, "oh", is represented by the symbol /oʊ/. The "s" sound is represented by the symbol /s/, while the "t" sound is represented by the symbol /t/. Finally, the last syllable "al" is represented by the symbol /əl/. Together, these sounds form the complete phonetic transcription of the word "costal cartilage".
Costal cartilage refers to a type of hyaline cartilage found in the rib cage that contributes to its structural integrity. It is a flexible and strong connective tissue that connects the sternum, or breastbone, to the ribs. The term "costal" refers to anything related to the ribs, while "cartilage" signifies its composition of a fibrous, elastic and hyaline matrix.
Costal cartilage is typically found in the anterior or front portion of the ribs, forming the connection between the ribs and the sternum. It allows for some degree of flexibility and movement in the rib cage, aiding in the expansion and contraction of the thoracic cavity during breathing. This enables the lungs to inflate and deflate as air enters and leaves the body.
The length and thickness of costal cartilage may vary among individuals, and such variations can affect the shape and size of the rib cage. Costal cartilages also play a role in protecting vital organs in the chest, such as the heart and lungs, by providing support and cushioning against external forces.
In some medical procedures, costal cartilage can be harvested and used as a graft material for reconstructive purposes, such as in nasal surgery or for repairing damaged cartilage in other areas of the body. Its regenerative properties and resistance to compression make it a valuable resource in various surgical applications.
• The cartilage forming the anterior continuation of a rib.
• The cartilaginous portion of a rib at its anterior extremity articulating with the sternum.

The word "costal" comes from the Latin word "costa", which means "rib".
The word "cartilage" comes from the Latin word "cartilago", which refers to "gristle" or "substance forming the skeleton of the body".
Therefore, the word "costal cartilage" combines the Latin word for rib (costa) with the term for a flexible connective tissue (cartilage) that is found in the area of the ribs in the human body, forming the connection between the ribs and the sternum.
